Smart Guages Accuracy

As you may know we are now running a 225 happymax, on the back of a 7.4m Redbay Stormforce, how accurate is fuel used on the smart guages, we have done no calibration of this, I Am sure there is none to do, is fuel used a reliable count of what leaves the tank, or are there precentage errors anyone has found cheers gavin

Gav,
See my earlier thread on smart gauge accuracy. It appears the best way to calibrate is to bring it to the petrol station. I have a 230 L tank so that should be fun.

we have 440 ltr capacity ouch

Found the same thing, empty the tank and then fill in 1/4 increments and calibrate as you go, very dull and very tedious.

Enjoy

I mean the fuel used info rather than fuel sender info

It kinda works for me , I used to run on full tanks then fill it up after a day. the fuel used guage would always give me a good reading

I'll second that, I find my tank gauge is always pessimistic, (better that than optimistic I guess!!) but my fuel used gauge is always spot on. My problem is trying to remember to reset it or take note of the reading when I refuel.

Fuel used always seams within a couple of litres, which i normally put down to an airlock when filling the tank.

The gauge only let me down once, when it reset to "0li used" about 40miles offshore. Arse. I did have the float gauge connected, which reported i was out of fuel somewhere by the needles - when i got back to the itchen and refulled i got 205li into the 220li tank - a little scary. I raised this with mercury/barrus but have heard nothing.
