I have a question regarding an electromagnetic flowmeter I’ve encountered these past few days
Thread Content
I have an electromagnetic flowmeter designed for DN25, with pipes that have a reduction from DN50 to DN25. The flowmeter we purchased is sized for DN50. I want to install this flowmeter now; so, by removing the DN25 reduction fitting and installing the flowmeter directly on the DN50 pipe, will it be necessary to mount the flowmeter in a vertical position to ensure accurate measurement? Does the flow meter need to be compensated?
What compensation does the poster mean? ? Is it thermobaric compensation? ? If so, I believe a liquid medium is not necessary
No compensation is needed; just ensure that the straight sections before and after are proper, that the pipe is fully filled, and that grounding and other related aspects are properly handled.
Electromagnetic flowmeters do not require compensation; it is sufficient to have a sufficient straight pipe section, and the pipe must be filled. Consult the process engineers – if the pipe is filled, the flowmeter can be used directly.
How do I compensate for measuring liquids? I’ve never heard that electromagnetic flowmeters need to be compensated; it’s sufficient to ensure the pipe is full.
