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:
MassFlowMeterFactor
The new mass flow meter factor is 0.9996.
