Having written already on the subject of fuel consumption and even carrying a picture of a friend’s power boat on this blog..I thought I would continue this worrying trend by writing about Garmin’s nice little flow meter – the GFS 10
This not only displays the current fuel level (based on initial reading less flow) but comes up with a single “Economy” reading (in nm/gal) that will have power boat skippers skipping with delight. This help a skipper see his nm/gal consumption automatically therefore taking into account current sea conditions, power applied, and speed over the ground. You can then have a good stab at optimising throttle position to give the best fuel economy. You can also connect up one sensor per engine.
So if you have the GMI 10 marine instrument display then you can connect up the GFS 10 fuel sensor using NMEA2000 – other GPSMAP 4xx and 5xx series units require Garmin’s own CANet™ connection.
Specs for the fuel sensor:
Maximum flow rate: up to 50 GPH per engine
Minimum flow rate: 2 GPH
Maximum back pressure: 0.5 PSI at 20 GPH/1.0 PSI at 40 GPH
