Here's what I bought for my KR. http://www.boat-fuel-economy.com/lowrance-lmf-200-for-sale
That's just the display. Fits a 2 inch hole. Needs to be connected to a Lowrance EP-60R transducer. It's a tiny little turbine installed in the fuel line that spins, the transducer converting spin speed to quantity used. http://www.lowrance.eu/products/sensors/ep-60r-fuel-flow-sensor/ They sell them for boats but work just as well on a plane. I've had to buy a new transducer some years back - used to be designated an EP-10 so they improved it and the new designation is EP-60R. The more you "train" it (calibrate it I meant to say), the more accurate it gets - that is, when filling up you tell the unit how much fuel you put in and compare that against what the gauge measured since last fill-up. You tell the unit how much fuel you actually used when filling up and after a couple times, it's very precise. Turned out though, especially after I had to buy a new transducer, to be more trouble than it's worth. You already know how much fuel your engine uses after you've flown it for awhile and the instrument is redundant. It's also scary . . . flying along and suddenly flow drops to zero if the transducer fails and then you're waiting for the engine to start sputtering thinking you've had a fuel pump failure or some other fuel problem. All in all, I haven't found it trustworthy or all that useful. It's another piece of information on the panel so if you have one that's dependable it's nice but it's very much a supplementary instrument. Nothing beats just knowing how much fuel you have on board and how long you've been in the air . . . in combination with a reliable fuel quantity gauge. It can be interesting for leaning the mixture but again, once you get to know your engine you'll seldom give the fuel flow meter any attention. That's been my experience with the Lowrance. Navman makes one which is supposedly more trouble free. A friend with an E-Racer had a Navman and liked it.
