Zeroing
After the flowmeter has been fully installed, you must perform the
zeroing procedure. Flowmeter zeroing establishes flowmeter response
to zero flow and sets a baseline for flow measurement. Refer to the
transmitter instruction manual for information on performing the zeroing
procedure.
Configuration, calibration, and
characterization
You can use the transmitter to configure, calibrate, and characterize the
meter. For more information, refer to the transmitter instruction manuals.
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 flowmeter tag,
measurement units, flow direction, damping values, and slug flow
parameters. If requested at time of order, the meter is configured at the
factory according to customer specifications.
Calibration accounts for the flowmeter’s sensitivity to flow, density, and
temperature. Calibration is done at the factory.
Characterization is the process of entering calibration factors for flow,
density, and temperature directly into transmitter memory, instead of
performing field calibration procedures. Calibration factors can be found
on the sensor serial number tag and on the certificate that is shipped
with the sensor.
For instructions about flowmeter configuration, calibration, and
characterization, see the manual that was shipped with the transmitter.
If the sensor and transmitter are ordered together as a Coriolis
flowmeter, the factory has characterized the meter — no additional
characterization is necessary. If either the sensor or transmitter is
replaced, characterization is required.
