Overview This chapter describes the following procedures: • Configuring pressure compensation – see Section 9.2 • Configuring external temperature compensation – see Section 9.3 • Obtaining external pressure or temperature data – see Section 9.4 Note: All ProLink II procedures provided in this chapter assume that you have established communication between ProLink II and the Model 2400S DN transmitter and that you are complying with all applicable safety requirements.
Pressure Compensation and Temperature Compensation 9.2.2 Pressure correction factors When configuring pressure compensation, you must provide the flow calibration pressure – the pressure at which the flowmeter was calibrated (which therefore defines the pressure at which there will be no effect on the calibration factor). Enter 20 PSI unless the calibration document for your sensor indicates a different calibration pressure.
Pressure Compensation and Temperature Compensation Figure 9-2 Configuring pressure compensation with a DeviceNet tool (1) Pressure measurement unit must be configured to match pressure unit used by external device. See Section 6.3. Set flow calibration (2) See Section 9.4.
Pressure Compensation and Temperature Compensation There are two ways to configure external temperature compensation: • If the operating temperature is a known static value, you can configure that value in the transmitter. • If the operating temperature varies significantly, you must write a temperature value to the transmitter at appropriate intervals, using an appropriate output assembly. See Section 9.4.

10.1 Compensation Chapter 10 Measurement Performance Overview This chapter describes the following procedures: Meter verification – see Section 10.3 • Meter validation and adjusting meter factors – see Section 10.4 • Zero calibration – see Section 10.5 • Density calibration – see Section 10.6 • Temperature calibration – see Section 10.
Measurement Performance 10.2.1 Meter verification Meter verification evaluates the structural integrity of the sensor tubes by comparing current tube stiffness to the stiffness measured at the factory. Stiffness is defined as the load per unit deflection, or force divided by displacement. Because a change in structural integrity changes the sensor’s response to mass and density, this value can be used as an indicator of measurement performance.
Measurement Performance 10.2.4 Comparison and recommendations • • - Meter verification requires approximately four minutes to perform. During these four minutes, flow can continue (provided sufficient stability is maintained); however, current process data will not be reported. - Meter validation for density does not interrupt the process. However, meter validation for mass flow or volume flow requires process down-time for the length of the test. - Calibration requires process down-time.
Measurement Performance During meter verification, you can choose between setting digital communications process variable values to the configured fault indicator or the last measured value. The values will remain fixed for the duration of the test (approximately four minutes). Disable all control loops for the duration of the procedure, and ensure that any data reported during this period is handled appropriately.

Measurement Performance 10.3.1 Uncertainty limit and test results The result of the meter verification test will be a percent uncertainty of normalized tube stiffness. The default limit for this uncertainty is ±4.0%. This limit is stored in the transmitter, and can be changed with ProLink II or a DeviceNet tool when optional test parameters are entered. For most installations, it is advisable to leave the uncertainty limit at the default value.
Measurement Performance 10.3.2 Additional ProLink II tools for meter verification • Visibility of configuration and zero changes – ProLink II has a pair of indicators that show whether the transmitter’s configuration or zero has changed since the last meter verification test. The indicators will be green if configuration and zero are the same, and red otherwise. You can find out more information about changes to configuration and zero by clicking the button next to each indicator.
Measurement Performance Therefore, to adjust volume flow, you must set the meter factor for volume flow. Setting a meter factor for mass flow and a meter factor for density will not produce the desired result. The volume flow calculations are based on original mass flow and density values, before the corresponding meter factors have been applied. 2. Calculate the meter factor as follows: a. Sample the process fluid and record the process variable value reported by the flowmeter. b.
Measurement Performance Example 250 MassFlowMeterFactor = 1 × ------------------ = 0.9989 250.27 The first mass flow meter factor is 0.9989. Compensation The flowmeter is installed and proved for the first time. The flowmeter mass measurement is 250.27 lb; the reference device measurement is 250 lb. A mass flow meter factor is determined as follows: One year later, the flowmeter is proved again. The flowmeter mass measurement is 250.07 lb; the reference device measurement is 250.25 lb.
Measurement Performance 10.5.1 Preparing for zero To prepare for the zero procedure: 1. Apply power to the flowmeter. Allow the flowmeter to warm up for approximately 20 minutes. 2. Run the process fluid through the sensor until the sensor temperature reaches the normal process operating temperature. 3. Close the shutoff valve downstream from the sensor. 4. Ensure that the sensor is completely filled with fluid. 5. Ensure that the process flow has completely stopped.

Measurement Performance The calibrations that you choose must be performed without interruption, in the order listed here. Note: Before performing the calibration, record your current calibration parameters. If you are using ProLink II, you can do this by saving the current configuration to a file on the PC. If the calibration fails, restore the known values. You can calibrate for density with ProLink II or a DeviceNet tool. 10.6.

Troubleshooting 1. Verify the DeviceNet node address and baud rate for the transmitter. If necessary, change their values using the digital communications hardware switches on the user interface (see Sections 8.10.1 and 8.10.2), and retry the connection using the new digital communications parameters.
Troubleshooting 3. Visually inspect the cable and connector. Ensure that contact is good at both ends, that the pins are not bent, the cable is not crimped, and the cable covering is intact. 4. Retry the connection using a different cable. Figure 11-1 DeviceNet connector 11.7.2 Checking grounding The sensor / transmitter assembly must be grounded. See your sensor installation manual for grounding requirements and instructions. 11.
Troubleshooting • All mass flow, temperature, or density values shown on the display or reported via digital communications • The mass total and inventory values • All volume calculations and data, including reported values, volume total, and volume inventory • All related values logged by Data Logger (a ProLink II utility) Compensation If simulation mode is active, the simulated values are stored in the same memory locations used for process data from the sensor.
Troubleshooting 11.12 Status alarms Status alarm codes are reported on the LCD panel (for transmitters that have a display), and status alarms can be viewed with ProLink II or a DeviceNet tool (see Section 7.6). All possible status alarms are listed in Table 11-2, along with the ProLink II message, possible causes, and suggested remedies. You may find it useful to acknowledge all alarms before beginning the troubleshooting procedures.
Troubleshooting Table 11-2 Status alarms and remedies continued Transmitter Transmitter in power-up Initializing/Warming mode Up • Allow the flowmeter to warm up (approximately 30 seconds). The error should disappear once the flowmeter is ready for normal operation. • If alarm does not clear, make sure that the sensor is completely full or completely empty. • Check the sensor circuitry. See Section 11.20. A010 Calibration Failure Mechanical zero: The resulting zero was greater than 3 μs.
Troubleshooting Table 11-2 Status alarms and remedies continued Alarm code ProLink II message A030 Cause Suggested remedy Incorrect Board Type The loaded software is not compatible with the programmed board type • Contact Micro Motion. See Section 11.3. A031 Low Power The transmitter is not receiving enough power • Check power supply to transmitter. See Section 11.4.
Troubleshooting 11.13 Checking process variables • Flow rate • Density • Temperature • Tube frequency • Pickoff voltage • Drive gain Compensation Micro Motion suggests that you make a record of the process variables listed below, under normal operating conditions. This will help you recognize when the process variables are unusually high or low. To view these values: With ProLink II, use the Status window and the Diagnostic Information window.
Troubleshooting Table 11-3 Process variables problems and remedies continued Symptom Cause Suggested remedy Erratic non-zero flow rate under no-flow conditions Leaking valve or seal • Check pipeline. Erratic non-zero flow rate when flow is steady Inaccurate flow rate or batch total 120 Slug flow • See Section 11.14. Plugged flow tube • Check drive gain and tube frequency. Purge the flow tubes. Incorrect sensor orientation • Sensor orientation must be appropriate to process fluid.
Troubleshooting Table 11-3 Process variables problems and remedies continued Cause Suggested remedy Inaccurate density reading Problem with process fluid • Use standard procedures to check quality of process fluid. Bad density calibration factors • Verify characterization. See Section 6.2. Wiring problem • Check the sensor circuitry. See Section 11.20. Bad flowmeter grounding • See Section 11.7.2. Slug flow • See Section 11.14.
Troubleshooting If slug flow occurs: • Check the process for cavitation, flashing, or leaks. • Change the sensor orientation. • Monitor density. • If desired, enter new slug flow limits (see Section 8.7). • - Raising the low slug flow limit or lowering the high slug flow limit will increase the possibility of slug flow conditions. - Lowering the low slug flow limit or raising the high slug flow limit will decrease the possibility of slug flow conditions.
Troubleshooting 11.19.1 Obtaining the test point values • With the display, configure the required test points as display variables. See Section 8.9.5. • With ProLink II a. Click ProLink > Diagnostic Information. b. Observe or record the values displayed for Tube Frequency, Left Pickoff, Right Pickoff, and Drive Gain. • Compensation To obtain the test point values: With a DeviceNet tool, execute a Get for the attributes listed in Table 11-4.
Troubleshooting 11.19.3 Drive gain problems Problems with drive gain can appear in several different forms: • Saturated or excessive (near 100%) drive gain • Erratic drive gain (e.g., rapid shifting from positive to negative) • Negative drive gain See Table 11-6 for a list of possible problems and remedies. Table 11-6 Drive gain problems, causes, and remedies Cause Possible remedy Excessive slug flow • See Section 11.14. Cavitation or flashing • Increase inlet or back pressure at the sensor.
Troubleshooting 11.20 Checking sensor circuitry • Inspecting the cable that connects the transmitter to the sensor • Measuring the resistances of the sensor's pin pairs and RTDs • Ensuring that the circuits are not shorted to each other or to the sensor case Compensation Problems with sensor circuitry can cause several alarms, including sensor failure and a variety of out-of-range conditions. Testing involves: Note: To check the sensor circuitry, you must remove the transmitter from the sensor.
