Twin engines - do i really need twin fuel flow sensors?

Hi

I am not being totally tight but I'm trying to find out if I really do need one fuel flow sensor per engine or can i use one sensor before the fuel lines split? I just want to know how many miles I have left in the tank.

I'm looking at Garmin GFS10 sensors as i have a Garmin plotter/sounder. All advice from Garmin is one per engine so you know performance per engine.

Thanks in advance for your advice!

I've never understood the point of having twins that both run off the same tank - but yes you could fit the sensor in the main line providing the total fuel consumption doesn't exceed the maximum range of the sensor.

My next RIB will have twins but with double batteries, tanks and fuel lines.
There is no point spending all that cash and having the common failure points that are relatively cheap to duplicate missing.

Thanks for your advice / thoughts.

All is doubled up / separate apart from the tank - i'm doing what i can to limit failure points without ripping out my 200l inboard tank. Long term I'll section the tank.

Back to the sensors - 2 will mean you might spot a problem with one of the engines early, however if you simply want to know how much motion lotion has been guzzled, one will work fine.
