Emerson IFT9701 Diagnosing zero failure, Configuration, calibration, and characterization

Flowmeter Startup continued

3.Fill the flowmeter completely with the process fluid under normal process conditions of temperature, density, pressure, etc., and ensure zero flow through the flowmeter.

4.Make sure flow through the meter is completely stopped, then press and hold the zero button until the LED remains on continuously. See Figure 5-1.

To end the zero operation before its completion, cycle power to the flowmeter.

The LED remains on continuously and the optional display reads “ZERO0” for up to one minute during zeroing. After the zeroing procedure has been completed, the LED again blinks ON once per second to indicate normal operation, and the optional display again indicates the flow rate.

5.5.2Diagnosing zero failure

If zeroing fails:

•The LED blinks ON four times per second.

•The flowmeter produces fault outputs.

•The blinking message “ELEC0” appears in the optional display. An error condition could be caused by any of the following:

•Flow of fluid during flowmeter zeroing

•Partially empty flow tubes

•An improperly mounted flowmeter

To clear a zeroing error, cycle power, then re-zero the flowmeter after correcting the problem, or abort the procedure by cycling power to the flowmeter.

5.6Configuration, calibration, and characterization

The following information explains the difference between configuration, calibration, and characterization. Certain parameters might require configuration even when calibration is not necessary.

Configuration parameters include such items as flow cutoff and damping values, flow direction, and milliamp output scaling. If requested at time of order, the meter is configured at the factory according to customer specifications.

Calibration parameters include the calibration factors for flow, density, and temperature. Field calibration is optional.

Characterization is the process of using a communication device to enter calibration factors for flow, density, and temperature directly into flowmeter memory, instead of performing field calibration procedures. Calibration factors can be found on the flowmeter serial number tag and on the certificate that is shipped with the meter.

To configure, calibrate, or characterize the flowmeter:

•Using a HART Communicator, see Chapter 6

•Using ProLink II software, see Chapter 7

You can also use AMS software to configure and characterize Micro Motion flowmeters. For instructions on using AMS software, refer to the AMS on-line help.
