Product Overview
FL-1 Overview
The FL-1 offers pilots an accurate, stable digital fuel level for single tank configurations. Not only does the FL-1 display the tank level digitally, it also provides a 210° graphical arc for immediate, quick reference of the tank fuel level.
The FL-1 can be ordered to work with a resistive probe (FL-1R-12 or FL-1R-24, depending on 12 or 24 volts), a capacitive probe (FL-1CA) or a 0-5 volt output such as with some Skysports probes (FL-1V). Please be sure to specify which model you need when you order your FL-1.
The FL-1 is not STC’d for installation in a certified aircraft.
Features
Fuel Slosh Stablization
When in flight, fuel will slosh around in the aircraft fuel tanks, creating irritating readings that constantly jump around. The FL-1 has a Fuel Slosh Stabilization calibration point that averages fuel level readings, creating a much more stable, but still extremely accurate fuel reading. Calibrate between a couple of seconds all the way up to over a minute of fuel slosh averaging.
9 Calibration Points
The FL-1 allows installers to program from as little as two all the way up to nine fuel level calibration points in the fuel tank. This flexibility eliminates inaccuracies due to non-linear fuel tanks.
Easy Programming Interface
The FL-1 is a simple instrument to install and program. Clear step-by-step instructions make programming the instrument easy to calibrate to your fuel tank senders.
Selectable Units
The pilot can easily select between displaying fuel level in Liters, Gallons or Lbs with a switch on the front of the instrument panel.

Customer Testimonials
I like being able to get a hold of a technical expert immediately when calling into the main EI phone number… The build quality of the sensors, display unit and EDC seem very good… I appreciate the business practices of EI and have had an EI R-1 Tachometer which has worked flawlessly for the past 20 years.

The reviews online were very good. Customer service has been great.
Nice Instrument, all the electrical information I need in one place. [I chose EI for its] performance and price.

The installation was straightforward and quite easy. Reliability and accuracy far exceed the original [aircraft’s] oil pressure/temperature systems. Also, the price was about a third of the cost to replace the gauge cluster.

Great Product, that provides a lot of very helpful engine data in an easy to use and see display! We are already finding cylinder cooling issues that we would’ve never known about before, and probably explains why we’ve had to replace that specific cylinder in the past. EI customer service on questions on how we wanted to set ours up was very helpful and positive. The CGR-30 had quite a few positive reviews online from other users.

EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
