Yes this sensor works with mpguino ,although a 10k ohm resistor
needs to go across the +12 power wire and output wire,1/4 watt is fine..
Provided you are feeding the flow sensor 12 volts the output wire then goes directlly to the mpguino injector input .
This mod creates a square wave output.
The sensor may need a 100nF capacitor across the output wire and ground wire if you have a noisy electrical system ,ceramic style at 50 volts will work fine.
