Pulse and 4-20ma


Thread Starter


I am using a flow meter with pulse output. But I also have to have an analog transmitter to change the pulse to 4-20ma because I need my controller to recognize the rate and send out an alarm if the flow is too low. (And I don't think pulse will do this, it only counts the total amount)

The problem is these analog transmitters i'm buying from Badger meters cost around $200 apiece. I would be need around 15 and they cost almost as much as the flow meters themselves.

Does anyone have experience with these stuff that can recommend a cheaper option?
