Maretron’s FFM100 fuel flow monitor is capable of monitoring engines from 20 hp to 3,000 hp. Three sensors are sold with the FFM100, each for a different horsepower range.


The M1 sensor is used for engines from 20 to 200 hp, the M2 for engines from 200 to 1,000 hp, and the M4 for engines from 1,000 to 3,000 hp. The FFM100 uses a positive displacement metering technology that delivers highly accurate data, says Larry Anderson, Phoenix-based Maretron’s vice president of sales and marketing. “The accuracy is nearly that of commercial vessel systems costing tens of thousands of dollars,” he says. The monitor can also be used for fluids other than fuel, such as water or oil, by ordering the appropriate flow sender. The FFM100’s two-channel control box is $395, and each sensor is sold separately: M1 ($395), M2 ($495) and M4 ($695). Contact: Maretron, (602) 861-1707.
