6.3 Measuring accuracy
Every electromagnetic flowmeter is calibrated by direct volume comparison. The wet calibration
validates the performance of the flowmeter under reference conditions against accuracy limits.
The accuracy limits of electromagnetic flowmeters are typically the result of the combined effect
of linearity, zero point stability and calibration uncertainty.
