2-CALIBRATION CERTIFICATE
All the electromagnetic fl owmeter are tested by 3 point rigs calibration.
The producer releases a document on letterhead certifying the average error of the 3-point calibration.
The calibration certifi cate is supplied with the unit.
The company archives the test data of each electromagnetic fl owmeter.
The calibration rig is certifi cated by N.I.M. (National Institute of Metrology), which is internationally recognizedby B.I.P.M.
(Bureau International des Poids et Metrologie) and complies with NTC ISO IEC 17025 standard.
All calibrations are made in accordance to EN 45001 standards and with an accuracy better than 99.97%
