The three main calibration principles for fluid flowmeter calibration useGravimetric,Volume or transfer standard calibration methods. Gravimetric calibration is one of the most accurate methods for flowmeter calibration both for volumetric and mass based flow calibration and is classed as a primary standard calibration.

How to calibrate a flowmeter?
Calibrate the flowmeter under test to conform with the master flow meter calibration. Gravimetric calibration is one of the most accurate and cost-effective volumetric and mass flow meter calibration procedures. The gravimetric method is ideal for liquid flowmeter calibration in oil, water purification, and petrochemical industries.
How to perform master meter calibration?
To perform Master meter calibration: 1 Place the master meter in series with the flow meter under test. 2 Compare the readings of the master flow meter and flow meter using a measured volume of liquid. 3 Calibrate the flowmeter under test to conform with the master flow meter calibration. More …
What is the difference between flow calibration and recalibration?
The main difference between the two procedures is that flow calibration is done before the meter is sent out for use while recalibration is done after the flow meter has been in operation for a while. Software tools can also be used to verify the accuracy of measurements after a flow meter has been calibrated.
What is gravimetric calibration for flowmeters?
Gravimetric calibration is one of the most accurate and cost-effective volumetric and mass flow meter calibration procedures. The gravimetric method is ideal for liquid flowmeter calibration in oil, water purification, and petrochemical industries.
