水流量装置是验证电磁流量计基本性能的最后一个关口,是重要的验收证据。为严守最后一个关口,正确标定电磁流量计,标定人员首先应具有流量仪表检定员的资格证书,这是最基本的条件之一。其次,水流量标定装置要取得有效的检定证书。对于0.5级的电磁流量计来说,证书中显示流量装置的扩展不确定度至少为0.15%。一般情况下,标准表水 Water flow device is to verify the basic performance of the electromagnetic flowmeter last pass, is an important proof of acceptance. To adhere to the last mark, the correct calibration of electromagnetic flowmeter, calibration personnel should first have the qualification certificate of flow meter testers, this is one of the most basic conditions. Second, the water flow calibration device to obtain a valid test certificate. For class 0.5 electromagnetic flowmeters, the certificate shows that the flow device has an extended uncertainty of at least 0.15%. Under normal circumstances, the standard water table
