Performing meter validation
To perform meter validation, measure a sample of the process fluid and compare the measurement
with the flowmeter’s reported value.
Use the following formula to calculate a meter factor:
Valid values for meter factors range from
0.8
to
1.2
. If the calculated meter factor exceeds these
limits, contact Micro Motion customer service.
Example
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:
The first mass flow meter factor is 0.9989.
One year later, the flowmeter is proved again. The flowmeter mass
measurement is 250.07 lb; the reference device measurement is
250.25 lb. A new mass flow meter factor is determined as follows:
The new mass flow meter factor is 0.9996.
