Turbine flowmeters are placed in a flow line and subjected to a gravimetric calibration or ballistic prover process, depending on the size of the meter.
A 10-point calibration is performed over its range at 10 different points to ensure and document linearity and repeatability…
The 10-point calibration is standard for most meters.
A calibration sheet is furnished with each meter, showing actual performance of the meter under calibration lab conditions.
Additional calibration points can be performed if required.
