Selection of electromagnetic flowmeters
Thread Content
The medium used now is reclaimed water, the pipes are 2 inches in diameter, and the maximum flow rate is 4 cubic meters per hour. Could you advise me on how to select the appropriate flow meter?

Your data volume isn’t high; what’s the conductivity of the reclaimed water?
As long as the flow rate is sufficient, a DN50 pipe will work just fine. A regular rubber-lined 316L electrode will do. Protection rating: It’s sufficient to indicate whether it has an integrated or separate structure
Full capacity is guaranteed, thank you:handshake
I don’t know the conductivity; this water is clean water that comes out of the treatment device
If it’s not pure water, using an electromagnetic method works just fine
For water with a diameter of 50, and a flow volume of 4 cubic meters, the flow velocity is only 0.56; a rotor-type sensor would be suitable, while an eddy current type sensor requires the diameter to be reduced in order to achieve the required Reynolds number； For electromagnetic effects, the conductivity needs to be considered; additionally, if the flow rate is too low, it may also be necessary to reduce the diameter
Such a low flow rate is almost at the lower limit for electromagnetic flow; if electromagnetic flow is really necessary, then the diameter should be reduced.
