Zero calibration provides the reference point for the flowmeter. It is necessary to conduct zero calibration whenever the Coriolis Mass Flowmeter installation is performed.
For zero calibration, perform the following steps after installation
1. Warm-up the flowmeter for 30 minutes.
2. After the warm-up time is complete, continue the flow through the flowmeter till the temperature of the flowmeter is same as the working temperature of the fluid.
3. After the flowmeter has reached the required temperature, close the downstream valve and make the fluid pass through the flowmeter under normal temperature, density, and pressure and then close the upstream valve to ensure that the sensor is full of liquid during the process of zero calibration.
4. Do the zero calibration of the flowmeter.
