Hello Listers,

I have been wondering how I can install a fuel flow meter with a fuel
injected engine or a Rotax 914.

Both types of engine have fuel return lines that lead excess fuel back to
the tank. A fuel flow meter on the fuel line from the tank to the engine
would therefore overread the used fuel amount.

Also, would the fuel return line necessarily have to go back to the fuel
tank or could it just be hooked back into the gascolator if the pump is
between the gascolator and the engine? In that case it would be possible
to put the fuel flow meter between the tank and the gascolator and have
accurate readings.

Don't want to stuff this one up, the sound of silence on the test flight
of my 914 would spoil the day....

Cheers,
Chris from Oz

Hi Chris,

I think this might be what you're after.

Put a flow meter on the line going to the engine, and another one on the
return line, and this little do-dad calculates the difference.

Cheers,
Peter

Some fuel flow monitors don't need a separate flow gauge on an injected
engine. They just count the pulses to the injectors. MGL's are one example.
Of course unlike a turbine flow sender that doesn't prove that fuel is
actually flowing.
