Reading the signal from a flow meter is easy; until you actually try and do it. A few missed pulses here and there leads to massive inaccuracies over a relatively short time. To accurately read and totalize flow rate, a subsystem must be used that has been specifically designed to do just that (hint don’t use your CPU to totalize flow; it’s busy doing other things).
The EZO-Flow can be used with your own pulsed D.C. flow meter, or it can be connected to one of the flow meters we offer.
