Product Overview
FP-5L Overview
What is the FP-5L? This instrument is the industry’s premium digital fuel flow monitor. Many fuel flow monitors are either quick to respond and unstable, or stable but very sluggish in response to mixture control adjustments. The FP-5L uses special proprietary algorithms which enable the instrument to display fuel flow that is rock solid, yet responds instantly to the slightest mixture change.
Not only is the FP-5L an outstanding example of precision craftsmanship, but the flow transducers that provide the instrument with flow information are literally hand assembled by Electronics International’s skilled technicians, ensuring every component of the transducer is finely tuned and balanced. This kind of obsessive attention to quality is one of the many things that sets our company apart from the rest, and is the reason why our flow transducers are used throughout the aviation industry.
FP-5L Features
- Displays Gallons per Hour, Gallons Remaining, Gallons Used, Time to Empty, % Horsepower, Fuel to Destination*, Fuel Reserve*, Nautical Miles per Gallon* and Statute Miles per Gallon*.
- Four pilot-programmable fuel alarms.
- Optional Fuel Pressure Measurement is available with upper and lower alarms.
* Requires GPS input.
Functions
Fuel Flow
Accurate, stable fuel flow with a resolution of .1 GPH. Flow can be easily set to display in British Gallons, Lbs, Liters, or Gallons.
Horsepower
Horsepower is based on fuel flow, and is accurate up to the leaning process. This function can be set to read in percentage or raw Horsepower.
Fuel Remaining
The FP-5L calculates the fuel remaining in your tanks with a .1 Gallon resolution. Two programmable “Default Full Fuel” levels allow you to quickly reset the instrument to “Full” every time you fill your tanks. Alarms will alert you when you’ve reached programmed limits for remaining fuel.
Fuel Used
Fuel Used during the current flight, as well as fuel used since your fill up is kept track of to the tenth of a gallon.
Time to Empty
Time to Empty is based on Fuel Remaining and the current Fuel Flow. An alarm will alert you when you’ve reached a programmable limit.
Miles Per Gallon
Accurately keeps track of your gas mileage. This function can be displayed in Statute or Nautical Miles per Gallon.
Recurring Fuel Used Alarm
The Recurring Fuel Used Alarm can be set for any whole number of gallons used, alerting you to change tanks at a programmable interval of gallons used. This is an excellent tool for fuel tank management.
Fuel Pressure
Optional Fuel Pressure Measurement is available with upper and lower alarms depending on your chosen package.

Your company shares a good reputation!
Installing [EI’s FP-5L] in my RV 6. . . owned an FP-5L, 6 years ago in a Cessna 206 on floats in a commercial operation in Alaska. Getting every ounce of payload, and coming home across Cook inlet with the Cessna gas gauges near or on empty, I spent a lot of time explaining the benefits of the Fuel flow gauge… and reassured my passengers there were 12 gallons of fuel on board. I’m a believer…
The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.
I have used your products in every airplane that I have owned over the years and have never had a problem. Thank You
