3.5Zeroing the flowmeter

Zeroing the flowmeter establishes the flowmeter’s point of reference when there is no flow. The meter was zeroed at the factory, and should not require a field zero. However, you may wish to perform a field zero to meet local requirements or to confirm the factory zero.

Note: Do not zero the flowmeter if a high severity alarm is active. Correct the problem, then zero the flowmeter. You may zero the flowmeter if a low severity alarm is active. See Section 5.4 for information on viewing transmitter status and alarms.

When you zero the flowmeter, you may need to adjust the zero time parameter. Zero time is the amount of time the transmitter takes to determine its zero-flow reference point.

A long zero time may produce a more accurate zero reference but is more likely to result in a zero failure. This is due to the increased possibility of noisy flow, which causes incorrect calibration.

A short zero time is less likely to result in a zero failure but may produce a less accurate zero reference.

The default zero time is 20 seconds. For most applications, the default zero time is appropriate.

You can zero the flowmeter with ProLink II or with the zero button on the transmitter.

If the zero procedure fails, see Section 11.6 for troubleshooting information.
