Discussion on the calibration cycle for flowmeters used in trade settlement
Thread Content
The instrument type is a Coriolis mass flow meter; the accuracy class of the instrument itself is 0.2, while the contract requirements specify an accuracy level of 1.0； In accordance with the requirements of the calibration regulations, the accuracy level must be better than 0.5 grade, with a calibration cycle of 1 year; for levels below 0.5 grade, the calibration cycle is 2 years. Can this table be used with a precision requirement of below level 0.5?
The flow meters used for trading in our factory are inspected once a year.
Personally, I think it’s feasible; it meets both the accuracy requirements and the specifications outlined in the calibration procedures
