Calibration device and method of anti-vibration and anti-electromagnetic-interference flowmeter

The invention discloses a calibration device and method of an anti-vibration and anti-electromagnetic interference flowmeter. The device includes a measuring pipeline, a vibration motor, an eccentricblock, an anti-vibration spring and a supporting part. An inlet of a to-be-marked flowmeter is flexibly connected with the measuring pipeline through a flange, the eccentric block is connected with the vibration motor and makes contact with one side of the measuring pipeline; the anti-vibration spring is arranged on the side, opposite to the eccentric block, of the measuring pipeline, one end of the anti-vibration spring is connected with the measuring pipeline, and the other end of the anti-vibration spring is fixed by the supporting part; the anti-vibration spring is basically perpendicularto the measuring pipeline, and the anti-vibration spring is in a compression or natural elongation states. The device can simulate the vibration and electromagnetic interference environment of the flowmeter in work, the flowme
