It’s really hard to understand how to choose a electromagnetic flowmeter for Cologne. Seeking advice

Find the selection guide and check it to find out. I guess there are 3 types: DN50, 80, and 100, with G4 and G3 likely corresponding to different electrodes. Actually, electromagnetic flowmeters don’t have to be imported; we can manufacture them using the available parameters

The selection of flow meters is generally similar; the most important thing is to pay attention to the minimum flow rate. The maximum and minimum flow rates determine the pipe diameter, and secondly, the material used depends on the properties of the medium and other factors

The manufacturer should provide information on the product; by comparing this information, it will be clear at a glance

There are original Cologne factory documents and parameter comparison tables. Feel free to contact me if you need anything.
