Fuel usage gauges - Digital. Anyone fitted one?

[alt]

Has anyone retro-fitted one of these to a boat? I don't really *need* one but it would make a nice little toy, plus it'd be handy to know how much fuel i'm using/saving at different speeds. I have a Volvo KAD32 and can easily get to the fuel line. My fuel gauge is pretty accurate and drops at a steady pace. The 'reserve' is pretty accurate at 40 litres

If anyone has fitted one. Any recommendations on what make one to go for?

I have the Navman FS35 wired into a T5110i plotter, pretty accurate so far. You can wire the fuel transducer into quite a number of the units. Gives fuel used, remaining, flow, range etc.

And the cost?

Fitted a Northstar F210 (same as the Navman one) It has been fine however have now had issues with water in the screen. CA Clase have sent me a new one so I will see how this goes.

Alt - I think these only work accurately on petrol motors, as a diesel will have a return line to the tank, so the measure of flow down the feed line will be a lot more than the motor is actually consuming

Navman do have a fuel management system for diesel engines but I don't think it will work with the 5110. It will measure flow and return & will work with the 5505 I think

The plotters vary from £250+ and the FS35 I got imported for around £40, think they are around £75 in the UK.

You can also wire the transducer into some navman fishfinders.

Ah yes, I suppose it makes sense to be hooked into the GPS and Fishfinder for MPG etc.

It was just an idea floating about my head... think i'll give it a miss this time.... Boys and their toys
