Would I be correct in assuming that to calculate the fuel flow you need to measure the outgoing fuel and then subtract the returning fuel?

So one needs two transducers....

thanks

You need two units which I have in my DynAero MCR-4S and depending on your instrumentation ie EFIS or other, your device will need to subtract one from the other to give you fuel flow.



I use a MGL EFIS with only one input with the trickery being done by a little device from sparxfly.co.nz (it takes the 2 inputs, subtracts and then outputs to the EFIS).

Hellou Peter,

please, exactly what "little device from sparxfly" do you have in mind?

I can´t find it on their web.

Thanks very much.

Stanislav

My system has calculated well and accurately with one transducer     only (between a returning fuel T and carburrettors).

     Cannot understand reason for two transducers...

Turbo engine fuel system is different. Normal flow rates would be:

     - forward flow 100 l/h

     - carburettor flow 20 l/h

     - return flow 80 l/h.
