My Floscan reads total gallons used since reset. When I fill up, I

I have a 2002 225 Merc EFI and want to hook up a FLO Scan (Series

meter or the NavMan Fuel Flow meter.

On the FLOScan, I see the on the gauge it shows gallons, how does it
know , if say , you have 75 gal in the tank and add 45 more gallons.
Is there and way to adjust this? Same question for the Standard
Horizion and NAvMan.
They all show the GPH but im curious how the gauge knows how much fuel
is in a half full tank. Or do you just need to start with a full tank
On the FLOScan I gues I would need the 0-32 GPH. Anyone have a 225
Merc EFI with some GPH numbers and rpm.

Thanks



I don't keep the tank full on my Parker. No need to carry around 170
gallons. I fill it to about 100 gallons, and save close to 500 pounds...
