Fundamentally you just need to keep track of the number of pulses received from the flow meter, though there may be a calibration curve to take into account. Starting with an mpguino would be the quickest path to an mpg (or L/100k readout methinks.
Do you have specs on it?
What's the range of flow rates it works with?
How much was it?
Thx.
