In the operation of Coriolis Mass Flow Meter we might meet the following problems.
1) Zero calibration
After correct installation, the Coriolis Mass Flow Meter should be powered at least 30 minutes for warm-up and then make the liquid pass through the flowmeter until the temperature of Mass Flowmeter is same as working temperature of liquid.
Afterward, close the downstream valve, make the liquid pass through the flowmeter under normal temperature, density and pressure and then
close the upstream valve to assure the sensor is full of liquid during the process of zero calibration.
2) Transducer (electronics) locked
