Hi Robert
I'm beginning to doubt my own logic on this thread :-\ but just think
about it for a moment. What we need to know is how much fuel the engine
uses/burns. All the rest of the fuel goes back to the tank. If you place
the Floscan, (I know of no other sensor that is acceptable) so that the
only fuel that passes through it is burnt by the engine then isn't that
what we want to know?
If fuel comes out of the tank and then goes back to the tank it hasn't
been used so won't be used to calculate fuel burnt by the totaliser.So
we don't need to know that, do we??
