These things are a can of worms, unreliable over time and expensive. . . I've had one of these almost the entire eleven years I've owned N335KC. I had to replace the sensor early on. Lowrance upgraded the sensor from an EP-10 to an EP-60. The sensor is the part that goes bad with all the different systems. A new sensor is about $165. The EP-60 needs recalibration so often that I've ended up just letting the gauge fill up the hole in the panel. Like you, I know how much fuel the engine uses and don't need the gauge . . . however, having said that, another source of real-time information is sometimes very valuable. This is the "display" part of the unit. It's called an LMF-200 https://www.youtube.com/watch?v=asDXo_U-51M The sensor is installed in the line after the filter and in a vertical position, preferably above the tank level but since that isn't possible in our planes with header tanks I've got mine mounted below. It might need less recalibration if I had it mounted above the tank, were that possible. They seem to have gotten more expensive over time. I'm seeing about $400 for the LMF-200 and the EP-60 sensor. Another of these units with a better reputation than the Lowrance is from Navman. FL-2100 on the display, sensor I don't know the number. Floscan seems to be top of the line when it comes to fuel flow sensors. Spruce carries the sensor and perhaps the display. All these things are originally for boats with gas engines. Customer service seems to be terrible no matter which one you buy, reading the forums. I was just reading about Dan's Red Cube and it seems over on Van's that, just like the Lowrance LMF-200 with the EP-60 sensor and the Navman, they work for some period of time then start failing so guys get on the forums to see if they can figure out why. It's such a common phenomenon, with all of the various fuel flow brands, that it's almost predictable. Of course, it's only the people who are having problems that show up on the forums. There may be thousands of these things working just fine in experimental aircraft.
