Which flow meter should be used
Thread Content
There are currently two electromagnetic flowmeters, of DN1000 and DN1200 sizes, and they have now broken down. I plan to switch to an insert-type model; after all, the pipe is quite large. I’m not sure which one to choose – a constant-flow type or an insert-type electromagnetic one? I’d like to ask everyone how to make a choice, what the advantages and disadvantages are. Thank you all!
I forgot to mention it – the medium in question is water; one type is cooling water and the other is chilled water

Ultrasonic waves can also work if precision is not strictly required.
Insertion-type electromagnetic flowmeters are easy to install and replace; our company specializes in manufacturing electromagnetic flowmeters of various specifications.
Insertion-type electromagnets have poor precision; anemometers are not resistant to dirt, and they tend to get clogged when there is a lot of debris
Use an external ultrasonic flow meter
I wonder what the price of external ultrasound devices is? Will it be too expensive?
The cooling water is a bit dirty, and there are also installation issues. I went to the site to take a look, and the straight sections before and after aren’t long enough, so I’m having trouble deciding how to choose the best solution

Choose an insert-type electromagnetic flowmeter; the existing cables can be used, and almost no other changes are required.
