How often should the electromagnetic flowmeter be calibrated?
The electromagnetic flowmeter is a flowmeter that calculates the flow through the induction electromotive force produced by the motion of the conducting liquid in the magnetic field by setting a magnetic field perpendicular to the direction of flow in the enclosed duct.
The provisions of the 7.4 verification period People's Republic of China national metrology verification regulation of "JJG 1033-2007": electromagnetic flowmeter flowmeter accuracy grade 0.2 and grade 0.2 is better than that of the verification period is 1 years, the accuracy level is less than 0.2 and the use of reference error of flow meter calibration cycle for 2 years.
The accuracy of the flowmeter is 0.2 and is better than 0.2. The calibration period is 1 years, and the calibration period is 2 years for the flow meter with the accuracy level below 0.2 and the reference error.
