Introduction to electromagnetic flowmeter standards and verification procedures

Electromagnetic flowmeter standards and verification procedures
EMF has two international standards. The standard numbers are IS0 6817 and IS0 9104. The former is the application standard, the latter is the performance evaluation standard. The domestic standard has the instrumentation professional standard ZBN 12007, which is the product standard. It is currently being formulated and equivalent to adopt international standards. Two national standards. The advanced industrial national standards are BS 5792 in the UK and ns B7554 in Japan. Japanese standard
The application is more detailed, especially the “Explanation” section is helpful for selecting instruments.
JJG 198 is the general verification procedure for speed flow meters in China. Although it is also applicable to EMF, it seems to be simple, and IS0 9104 is more detailed.
The draft international standard ISO/CD 13359 is the distance between the planes of the flanged flow sensor flanges being developed.
