2 fuel flow sensors in series

The Jackeens · 08 March 2005, 15:47

anyone know or have experience of having 2 fuel flow sensors in series. not sure if there will be a problem . The etec has one for its smart gauge and the navman 6600 also has one which give more info. I' ve had no joy out of Jets , kinda expected that

It depends how close the sensors are placed together and if they use an impeller or not. Some large volume gauges use a magnetice device (Mag meter) to work out the volume but the fluid needs to be constant and have no turbulence in the flow. Impellers meters close to each other will result in the second one giving incorrect readings.

I've got loads of info on this if you want but its more to do with high volumes. Let me know and I can bring it to this weekend or PM me and I`ll email it to you.

Be careful. There will be a small pressure drop accross each sensor. Add all these up and you could find the fuel flow at WOT is reduced, leading to more serious problems.

Maybe someone can clarify this?

I do know that the Optimax engines are recomended not to have a fuel flow sensor - I realise you have an ETEC so it's not 100% relevant ...............

I can bring a photocopy of a doc on Saturday which tells all.

Ribnet wont let me post it up as its a pdf and too big. If you really want it PM me with your email address and I`ll send it in two bits.
