What is the output for this flow meter? Also, what readout/display should be used with it?
Greetings,
That device is one among numerous semi-generic examples of type, which place a magnet on a rotating impeller in the flow stream which triggers a hall effect sensor as it rotates, generating a pulse output with a frequency thatโs approximately proportional to flow rate.
If I read correctly most of these outputs are of an open-collector flavor, so a pull-up resistor would likely be needed. Beyond that, most any device youโd care to use to count pulses and display as a rate or tally of such could work. Thereโs some example code here that looks to target an arduino sort of environment, else a person could probably find a tachometer/pulse counter sort of device in more integrated form if desired.
