Mass flow meter accuracy issues
Thread Content
The company has a mass flow meter (E+H) for trade settlement purposes. A precision of 0.2% was required, but when I asked the manufacturer, they said that it’s very rare across the country to find laboratories that can issue certification reports with a precision of 0.2% (not calibration reports). His explanation is that, using the 0.1% gauge as the standard for measurement, a precision report with an accuracy at least three times that of the standard gauge must be provided (a report based on 0.2% accuracy is not acceptable); generally, a precision report with 0.5% accuracy is provided. Gentlemen, is that really the case? Is it possible to use mass flow meters for trade settlement? Please take a look. Or is 0.5% used for all trades?
Bro, when it comes to trade settlement and matters related to money, the higher the precision, the better. Where are you from? The precision in trade transactions can reach 0.1%. As for mass flowmeters, Emerson’s Coriolis meters are the best option. Make sure to study the relevant information carefully so as not to get scammed.

According to regulations, can a value of 0.1 be used to calibrate one with a value of 0.2?
Is there an institution that can calibrate 0.2 mass flowmeters? China
China does not have calibration equipment capable of detecting 0.2%. Mass flow meter manufacturers: we can achieve 1%, but the certificate still shows 1.5%. . 13828408007
