Controlotron system 1010 uniflow manual

Ideally, you will be able to use the primary recommendations. However, you can edit the menu entries as required to accommodate different transducers or mounting configurations. The flow computer will adjust its parameters to optimize performance based on your selections.

The Ltn menu cell shows the required spacing distance in inches or millimeters between the upstream and downstream transducers. You can define the empty pipe and zero flow values once the transducers are operational. Once you select the Use this menu cell to select the type of transducer to be installed. These menu cells identify the spacing indices on the spacer bar. You must use these settings to mount the transducer properly. This menu cell shows the actual spacing distance required between the transducers.

This menu cell allows you to select a mounting mode. This menu cell indicates the model number of the appropriate spacer bar for your transducers and spacing requirements. Use this menu cell to inform the meter that you completed the transducer mounting.

After the transducers are operating, you can use this menu cell to set the empty pipe threshold. You can choose from either the [ Universal] or [H High Precision] transducer lists, or from a list of [ Universal] models. You should consider using high precision transducers for extremely critical applications. We usually recommend these transducers for custody transfer, leak detection or nuclear power applications.

The system default is [] Universal]. If this suits the application, bypass this menu cell by pressing. To select a Transducer Type: To access the [Xdcr Type] option list press To move the cursor to the required transducer model press To store your selection press. The flow computer generates this list automatically based on your pipe and your application data entries.

The left-most transducer size e. The right-most transducer e. Since these are simply recommendations, not requirements, you can override the flow computer and use any size, as long as the mounting method accommodates the pipes diameter. The flow computer shows that your selection is acceptable if it is able to calculate transducer spacing Ltn.

To select a Transducer Size: To access the [Transducer Size] option list press To move the cursor to the desired transducer size press To select the transducer press.

In almost all cases it will be Reflect, since this is the most desirable configuration. Reflect mode allows you to mount the transducers on pipes that do not permit back or side access.

Reflect mode provides inherent compensation for flow profile distortion crossflow that could be the result of unfavorable application conditions such as an insufficient upstream straight run. In addition, Reflect mode supports the AutoZero function, which sets the zero flow velocity automatically.

Direct mounting may produce a stronger transducer signal and requires less mounting length than Reflect mounting. This can be important if the liquid or pipe material exhibits high sonic attenuation, thereby preventing operation in the Reflect configuration.

To select a Xdcr Mounting Mode: To access the [Xdcr Mount] option list press To move the cursor to the required mounting type press To store selection press. It will recommend the use of either a mounting track, a spacer bar, or independent mounting. The flow computer will list the part number of a mounting track or spacer bar. Note: If you select Universal Transducers, this function is not provided. If it decides upon independent mounting, it will report the distance required between the two transducers.

In this case, you have to make sure that when you mount the transducers, the space between them equals the length specified in the Ltn menu cell. See Section 3 for details on how to accomplish this. This is the first step in establishing the correct distance between the transducers. Spacer bars and mounting tracks utilize number indices i. One transducer is located at the Reference position, while the other one is located at the Number Index position. The Number Index cannot be directly edited.

However, the Spacing Offset can be changed via its option list. Changing the Spacing Offset will alter the reported Number Index. Maximum spacing offset provides moderately greater signal levels but, in some cases, slightly decreased zero flow stability.

Note: This mounting method is different for the System Flowmeter. If the flow-computer reports Use Ltn, you have to measure the distance between the upstream and downstream transducers. The flow computer issues the actual distance between the transducers in inches or millimeters See Ltn. Please consult Section 3 for details on how to use the Ltn measurement. Note that, even though using Ltn does not call for the physical use of the Number Index, you can still change the Spacing Offset to influence the strength of the transmit signal.

System uses a pair of precisely matched transducers so you can select either one for the Reference position. You must connect the Up transducer cable to the transducer mounted on the upstream side of the mounting track. This enables the meter to display the flow direction correctly. It is important that you note each transducers serial number and its Index position during the original installation because, to reinstall the flowmeter successfully, you must remount each transducer in its original position.

Transducer pairs have matching serial numbers except for the appended letters A and B. This helps you to identify each transducer. To select a different Spacing Offset To access to [Spacing Offset] option list press To move the cursor to the desired offset press To store selection press. After selecting the mounting method, the flow computer checks entries for pipe size, transducer type, etc.

Use this number index to position the transducers at the proper distance apart when using a track or spacer bar. While this positioning provides the best signal strength in most cases, there are situations where either more signal quality or more amplitude is desired.

This can be accomplished by moving the cursor to [Spacing Offset] and selecting either Min for a better signal quality, or Max for greater amplitude.

After selecting Min or Max, the computer will recompute a different Number Index. Move the transducer to that new position. The Number Index like the provides the spacing between transducers while Letter Index provides for changes, if necessary, for signal strength and amplitude. Higher letter indices provide greater signal levels but, in some cases, slightly decreased signal quality. For transducers mounted independently and where manual measurements of the distance between transducers must be determined e.

Please review Section 3 for details on how to use the Ltn measurement. You must connect the Up transducer cable to the transducer mounted on the upstream end of the mounting track.

This lets the meter report the flow direction correctly. It is important that you note each transducers serial number, its Index position during the original installation, and whether it is in the upstream or downstream position.

If you cannot recreate the original installations exact physical arrangement, it will be necessary to do a New Install. In addition, please note that transducer pairs have matching serial numbers except for the appended letters A and B. These letter designations help you identify each transducer. The Number Index establishes the spacing between a pair of transducers.

You cannot override this recommendation. To complete the transducer installation, you must accept the Number Index by mounting the transducer at that point on your spacer bar or mounting track. Initially, the flow computer bases its Number Index selection on the pipe diameter and estimated liquid sonic velocity Vs you entered in the Application Data menu.

When you Invoke the [Install Completed? In some cases, it may prompt you to re-space the transducers to another number index. If you are mounting the transducers without a track or spacer bar, you will have to space them according to this value see Section 3 for details.

Note that Ltn may be a negative number for direct mount on very small pipes where the transducer spacing overlaps. To start the [Install Completed?

Install transducers as required refer to Section 3 for procedures. Mount the transducers using the selected mode direct or reflect. Please refer to the transducer mounting procedures detailed in Section 3. When using a mounting track or a spacer bar in reflect mode, locate the first transducer at the Reference Index and the second transducer at the recommended Number Index.

If you are mounting the transducers independently, you must use the recommended distance; Ltn to space the transducers. You must use the proper sonic coupling compound. The pipe must be completely filled with a liquid, which can be either flowing or at zero flow. After transducers are properly mounted, the flow computer completes its Initial Makeup command and the [Install Completed?

To access the [Install Completed? The Short Burst pop-up windows will appear as shown below. The Transfer Install function allows the transducers to be optimally positioned for a different fluid, without the need for a new Initial Makeup procedure see the Water Calibration addendum in this manual for details. The [Install Completed? Force Transmit Procedure This diagnostic software routine allows the user to force a transmitting condition that can be use to search for an amplitude level ALC when Detection Fault or Low Signal alarms are present.

The routine forces the flowmeter to generate constant transmit bursts while reporting current receive signal strength for the user. To initiate the Force Transmit function, refer to the Short Burst detection mode example shown below. Controlotron Drive 0.

A typical menu screen will appear as shown below and indicate the current ALC e. This ALC number indicates the current receive signal strength and can be used for further diagnostic purposes. If the Force Transmit diagnostic procedure is not used, the normal [Install Completed? The current Initial Makeup activity, for example: Drive 14 m 10 [] appears at the top of Display Screen.

During the Initial Makeup, the flow computer verifies your site data, records the sonic characteristics of the pipe and liquid and then adjusts internal parameters to optimize flow measurement. Please remain patient. This process can take several seconds or several minutes to complete.

There is no relationship between the length of an Initial Makeup and the meters subsequent performance. An Initial Makeup for larger pipes and more demanding application conditions simply takes a little longer. Upon sucessful completion of the initial makeup, the will show you a pop-up window with the measured Vs as shown below.

You can then use the numeric keys to type a different value. However, only edit the Measured Vs when you are certain of your liquids actual sonic velocity. If, however, there is a large discrepancy between the measured Vs and the actual Vs, then consider that an accurate Vs measurement depends on certain parameters that the flow computer cannot sense directly e. In other words, entering incorrect pipe parameters or not using the recommended spacing could result in an erroneous Vs measurement.

Press the MENU key to display flow. In cases where the actual Vs differs noticeably from the estimated Vs, the computer may issue a re-space command. Repeat the initial makeup process. You can override a re-space command by simply keying the [Down Arrow]. Therefore, only consider editing the measured Vs after you remove all the primary causes for an inaccuracy. Check your pipe dimensions and pipe material entries.

Re-check the transducer spacing and part numbers. Large Vs discrepancies are almost always due to erroneous pipe data or incorrect transducer placement. To accept the Measured Vs: Press. If you decide to edit the Measured Vs: To activate numeric entry press Use the numeric keys to type the new Vs value in meters-per-second. To store the corrected Vs press. Remount the transducer at the new Number Index.

To repeat the Initial Makeup process press After the flow computer completes its Initial Makeup command, the [Install Completed? This resets the option list. You can now repeat the install routine described previously. The [Empty Pipe Set] option list allows you to re-invoke MTYmatic, use an Actual MTY routine if application conditions allow you to empty and refill the pipe or use the Set Empty routine to set the empty pipe threshold by direct numeric entry.

This is the recommended way to define the empty pipe threshold. Empty the pipe completely, then press menu prompt line.

Refill the pipe completely, then press. How to Use the Set Empty Command Use the Set Empty command to enter a number that represents the signal strength level consistent with an empty pipe. Set Empty uses non-linear scaling. There is no direct correlation between the number you enter and any standard amplitude unit. If you set the number too low, the meter may not detect a true empty pipe. If you set it too high, it could trigger the empty pipe alarm, suspending flow measurement, even though the liquid is flowing.

Use the numeric keys to type a new Set Empty number. To store the Set Empty number press. Unlike turbine meters ultrasonic transit-time meters provide active flow measurement right down to zero flow, however, the measurement of the transit-time delta is dependent on the similarity or match of the electronics, cables and ultrasonic transducers.

Consequently some flow offset or zero offset may be present in any installation. To eliminate this residual zero offset Controlotron has developed several different methods to insure proper zero flow compensation. The following paragraphs describe each method and when they should be used. AutoZero When the transducers are mounted in the Reflect Mode configuration see paragraph 3.

Flow does not have to be stopped to perform AutoZero since only the pipe wall signal is used in determining the zero offset and not the liquid component. The AutoZero routine performs a one-time analysis of the pipe wall component of the ultrasound signal to quantify any residual mismatch in the hardware. Once the AutoZero routine is complete, the system memorizes this measured zero offset and subtracts this value from the flow reading. Actual Zero The Actual Zero function simply averages the indicated zero flow readings over a user defined time period then stores this average value in memory.

Under normal operation the indicated flow reading is zero compensated by simply subtracting this memorized value from the uncompensated flow reading. Actual Zero is the most positive method for zeroing the system, however, flow must be stopped with the line blocked if possible before invoking this function. If stopping flow is not possible then an alternate zeroing method should be selected. ReversaMaticTM This routine involves swapping the UP and Down transducers on the pipe while keeping the cables attached such that the difference in the transit-time change represents the zero offset.

The fixed zero offset value is stored in memory in the same manner as described in Actual Zero. This routine would generally be used whenever flow cannot be stopped and the transducers cannot be mounted in the Reflect Mode configuration.

Flow must be stable during the entire process. However, after this analysis is complete the flowmeter continues to interrogate the pipe wall signal and update the zero offset value under normal operation, such that the flowmeter dynamically compensates for changing conditions which would normally result in zero drift. ZeroMaticTM will only operate with the transducers mounted in the Reflect Mode configuration and is recommended for applications which experience large temperature extremes.

If any zero offset remains after flow is stopped, an Actual Zero can be performed without interrupting ZeroMaticTM operation. A pop-up window prompts you to set the current flow rate in selected rate units to equal zero 0. NOTE: If a flow offset is desired i. When you send the command, the flow computer analyzes the current flow rate for up to sixty seconds, integrating averaging the data for the best zero correlation. During this time, the menu prompt at the top of the display screen shows a timer that counts from zero to sixty.

This controls the amount of data the meter averages to obtain a zero level. Using ReversaMaticTM If site conditions do not permit stopping the flow rate at the mounting location, and you do not know the current flow rate, then you can use the ReversaMaticTM routine to establish the zero flow level.

You should perform the ReversaMaticTM procedure as quickly as possible to ensure that the flow rate remains constant throughout the procedure. To invoke ReversaMatic:! The meter begins to measure the positive flow rate. Positive flow refers to flow moving from upstream transducer location to the downstream transducer location. Note top prompt line shows: Reversamatic Action. When remounting the transducers, couple them to the pipe properly.

Now remount the transducers for normal operation in their original orientation. When remounting transducers, couple them to the pipe properly. This completes the ReversaMaticTM procedure. The systems zero accuracy will be very close to that obtainable using the Actual Zero method, providing flow remained constant during this procedure. Important Note: A caution on the use of upper and lower flow limits used to prevent flow misregistration prior to using the Reversal Zero technique ReversaMatic : If the negative flow rate that the meter reads in the step during which the transducers are reversed is more negative than the lower flow limit, the meter will re-register positive and the Reversal Zero cycle will thus be corrupted.

Therefore, postpone the installation of upper and lower flow limits until the reversal zero procedure is executed successfully. For pipes that combine large diameters with very high flow velocities, it may be necessary to move the upper and lower flow limits out of the way until the reversal zero is completed.

Moreover, pipes of this size frequently have excellent intrinsic zero performance and may not even need zeroing.

Invoking ZeroMaticTM clears any existing fixed zero offset. Use this menu cell to select the ZeroMaticTM option. Invoke the ZeroMaticTM initial makeup procedure as previously described above. While ZeroMaticTM initial makeup is running, press disabling the function.

This menu becomes available after picking a meter type and measurement channel. We recommend that you use it after the transducers are installed and operating to finetune the meters output characteristics. Each application presents different data display and output requirements due to unique pipe and liquid conditions.

Use the Operation Adjust menu to match meter operation to the site. You can set damping controls for the primary flow rate output. You can define an energy or flow Deadband usually a very low flow rate below which the flow output will be forced to zero.

You can also select the meter response to a continuous Fault condition. Use this menu cell to select either SmartSlew or Time Average output damping. Use this menu cell to enter a flow rate deadband threshold. Flow rates below this level will be reported as zero flow. Use this menu cell to select meter response to a fault condition.

Fault drops outputs to zero. Memory retains last valid reading for duration of Memory Delay. Use this menu cell to enter the duration in sec. The hidden cell only appears if you select Memory Mode. SmartSlew recommended provides the best combination of data smoothing and quick response to sudden rate changes.

It performs data scatter damping during steady flow periods while maintaining the ability to respond instantaneously to changing flow rates. SmartSlew values range from [1 to 9]. The default is [6]. Pick a higher number to slow meter response to a rate change. Time Average integrates the instantaneous flow rate over a selectable time period. You enter a value in seconds , which sets the time it takes the meter to respond to a rate change.

The default is 10 seconds. You can enter any amount of time up to 60 seconds maximum. Scroll the numeric list to the desired choice press To register the new value press. To register the new value press.

It will prevent the possibility of data scatter a natural result of digital computation from causing false totalizer accumulation during long nonflowing periods.

Inspect the actual data scatter during zero flow conditions to find the proper deadband setting for your application. To edit the default setting 0. The Fault setting default will zero the flow rate output and declare an alarm on a flow display screen, Datalogger report and an assigned relay output. For some applications, however, occasional temporary Fault conditions may be a normal part of the process and would not require an alarm response.

The system offers a Memory operating mode to support such an application. Memory Mode suspends the systems Fault response by preventing the flow outputs from dropping to zero for the interval specified in the Memory Delay menu cell.

During the Memory duration, the meter will maintain the last valid flow reading measured before the onset of the fault condition. The default Memory Delay is 60 seconds. You may select any duration from 3 to , seconds one week. This moves the highlight to Memory Delay sec. It allows you to specify the number of seconds that the meter maintains its last valid flow reading. When the memory delay expires, it triggers the fault alarm response described previously. To specify the Memory delay: To enable numeric entry press Use the numeric keys to type the delay in seconds.

This menu is available after selecting a meter type and measurement channel. After making your selections, a view-only menu cell shows the resultant scaling. Use this menu cell to select either volumetric or mass flow rate units. Use this menu cell to select a time base for the flow rate units.

Use this menu cell to select a range for the flow rate display screen. Use these menu cells to set the scaling for the flow rate and flow total outputs. Use this menu cell to enter a volume accumulation for the batching or sampling totalizer relay trigger. Imperial Gal If you select mass units, the meter uses the specific gravity parameter see Application Class section to convert volumetric flow to mass flow.

The default English Units is [Gallons]. The system default is [Minutes]. To select a Time Unit: Press. The Autorange selection increases resolution automatically at low flow rates and reduces resolution at high flow rates as required to prevent data overflow. If you select High Range, the meter controls its screen resolution to prevent data overflow at the highest possible flow.

The [Flow Display Scale] menu cell shows the results. If the displayed scaling is not suitable, you can edit it by accessing the option list. Note that this scaling applies to all flow rate data displayed on the flow display screen, even if the units do not appear next to the data because there may not be room on the screen. Therefore, always keep this prefix in mind when you enter flow related data. To select a different Flow Display Scale: To access the [Flow Display Scale] option list press Move the cursor to the desired display scale by pressing To register selection press.

If you select mass units, the meter uses the specific gravity parameter see paragrah 2. If this suits the application, press to bypass this menu cell. To change the default setting: To access the [Total Volume Units] option list press To move the cursor to the desired Total volume units press To store selection press.

The [Totalizer Scale] menu cell shows the results. Note that this scaling applies to all flow total data displayed on the flow display screen, even if the units do not appear next to the data because there may not be room on the screen. Always keep this prefix in mind when you enter totalizer-related data. To select a different Totalizer Scale: To access the [Totalizer Scale] option list press Move the cursor to the desired display scale by pressing To register selection press.

It provides three resolution or capacity levels: x x00 x0. Actual Totalizer display units depend on the selected multiplier. Check the total units by accessing the Totalizer Scale menu cell. The meter sends a totalizer output pulse for every advance of the rightmost visible totalzer digit.

It is possible for a high flow rate to persist long enough to exceed the relay outputs 2. If this occurs, the meter will store excess pulses in an overflow buffer, and route them back to the relay when the flow rate drops enough to allow the TOTCNT output to catch-up. Exceeding the 2. If this occurs, the meter will be unable to indicate the current flow total. Therefore, select a resolution toensure that, even at the maximum expected flow rate, the TOTCNT pulse will not be activated more than 2.

Note that resetting the Totalizer also clears the overflow buffer. To change the default resolution: To access the [Total Resolution] option list press Move the cursor to the required resolution by pressing To store selection press. NOTES Accumulates flow in positive direction only Accumulates flow in reverse dirction only Adds to positive total; subtracts from reverse total.

It minimizes false Totalizer register increments due to data scatter. Press to accept the default setting. To select a Totalizer Mode: To access the [Totalizer Mode] option list press Move the cursor to the required Totalizer mode by pressing To store selection press. For example, if a sample of an oil product needs to be taken once every thousand barrels, the user can set the flowmeters relay to trigger an external sampling device at that interval.

Unlike the Flow Total registers, you cannot view this register directly. It is used for relay control only. The numeric entry must reflect the selected flow total units. The Totalizer Display Scaling menu cell shows the applicable flow total units.

To store data press. Totalization will not resume until you repeat the Fn and Numeric 2 key sequence. However, the flow computer will continue to update its internal registers. The flow computer will show the current total when you repeat the F1 - Numeric 3 key sequence. Clears the Makeup Latch. See paragraph 4. Span Data. This menu becomes available after picking a Meter Type and Measurement Channel. However, some functions will only be active after the transducers are installed and operating properly.

Additionally, the Calibrate Flow Rate menu allows you to apply external adjustments to the meters intrinsic primary outputs. Use this menu to set the low and high range for analog outputs. Use this menu cell to enter a calibration slope factor for volumetric flow Vfo.

Each menu cell shows appropriate rate units and time base. If you change flow rate units after spanning the system, the computer automatically updates the output data setup to reflect the change. Span limits apply to both the analog outputs and the on-screen stripchart.

In addition, temperature ranges can be set if an optional temperature sensor is supplied. The minimum and maximum flow rate entries establish the Vfo span. Use signed numbers for bi-directional spanning.

Note that negative reverse flow always is lower than positive flow, whatever its absolute magnitude. Vf is the absolute magnitude of the volumetric flow rate Vfo. There are no menu cells provided to span this output. Vf shares the Vfo span entries. The Vf minimum span is always zero. The maximum span for Vf is the largest absolute value of either the min.

The min. Vs entries establish the Vs span. It can be a positive or negative value. Enter the data using the flow rate units you selected. This entry also spans the unsigned flow variable Vf. To enter the Max. To store the data press. It can be a positive or negative value to reflect bi-directional flow. However, the minimum span for the unsigned flow Vf is always zero. The sonic velocity Vs appears on the Stripchart display and can drive any analog output or the alarm relay.

The sonic velocity Vs can be displayed on the Stripchart and drive any analog output or the alarm relay. Alarms appear locally on the LCD digital display. In addition, you can use the Relay Setup menu to assign those functions to the systems relays. You may select from high or low flow rate, liquid interface Vs and liquid aeration alarm functions.

Entry of all alarm setpoints is accomplished using the selected rate units. The entered value must fall within the volumetric flow Vfo analog span for the Hi Alarm cursor to appear on the Graphic Screen. The entered value must fall within the volumetric flow Vfo analog span for the Low Alarm cursor to appear on the Graphic Screen.

It can compare sonic velocity differences in real-time. Its sonic velocity detection is so sensitive, it quickly distinguishes between two different liquids flowing through the same pipe. To set the interface alarm, you select a detection setpoint that falls between the Vs values of the two liquids. The Interface Alarm becomes active when the measured Vs meets or exceeds the reference value you enter in this menu cell.

To enter an Interface Vs alarm setpoint: To activate numeric entry press Use the numeric keys to type the Interface Vs value in meters-per-second. Some applications may require an alarm indication if aeration exceeds a particular level. The meter detects this aeration level and provides this data as an output. The aeration percentage triggers the alarm relay whenever it meets or exceeds the threshold you set in this menu cell. The digital display screen also shows the current aeration percentage.

NOTE: Severely aerated conditions may induce meter fault. For intermittent faults, see memory interval in the Output Control menu. Makeup Latch A fault condition caused by an empty pipe or a transient loss of power, etc.

After recovery from the fault, the meter automatically executes an inprocess makeup to restore operating parameters. During the makeup, the meter sets a Makeup Alarm flag, which clears upon completion. Therefore, unless you were monitoring the unit continuously, you could miss the fact that an in-process Makeup occurred and subsequent Totalizer counts were lost.

In addition, if the This ensures that the Alarm does not appear on succeeding Datalogger reports. A Makeup Alarm appearing on a subsequent report indicates that an In-Process Makeup must have occurred since the last Datalogger report.

We are thus confident that in any given application, the majority of conventional flowmeters can not possibly match the systems measurement range or its linearity.

However, some applications may require an output adjustment to match an official external reference. The right-hand column shows the active calibration mode. Selecting either of the external calibration modes will not eliminate the Intrinsic factory calibration.

You can use this menu cell to switch between Intrinsic, Kc or Multipoint at any time. Kc Calibration For most applications, the measured flow range produces a linear meter response. Uniflow meter. Custom Bundle:. Bundle Description:. Modified Item:. Modification Description:. United States.
