Fuel Sender Models & Specifications

With 100,000 magneto-resistive fuel sensors in the field and over 900,000 hours of trouble-free operation, we are trusted by aircraft manufacturers, discerning organizations and individuals. Our digital aircraft fuel senders exceed 90,000 hrs. mean time to failure (MTTF) making our product one of the most reliable aviation systems in existence.

The initial STC allows the CiES fuel sender to replace the existing fuel quantity senders in many aircraft, including: Britten Norman, Beechcraft, Cessna, Cirrus, Fairchild, Gippsland/Mahindra, Grumman, Maule, Mooney, Piper, Socata and Vulcanair.

CiES CC-Series fuel senders are TSO certified to C55A and associated SAE AS405C. They have met all the DO-160(F) and DO-254 DAL (Design Assurance Level) Level D requirements for the TSO.

We tried a number of resistive float senders with terrible accuracy. With CiES senders, our indicated fuel is within 0.5 gallons of the EDM830 totalizer every time!

Amazing technology. After 35 years flying my 182, I installed CiES senders and G275 EIS and the fuel shown and pumped is always accurate to the gallon. Wonderful!

Magnetic Field Advantages

Our magneto-resistive solution keeps electronics out of the fuel tank, while producing unparalleled accuracy and longevity. How does magnetic field technology compare with the other four traditional measuring methods? Find out here.

Float System Accuracy

It’s a simple solution to a complex problem - measuring fluid or fuel level in an enclosed, invisible space. Quite simply, the float system was never the problem, the sensor was.


Next Generation Can Trust Their Fuel Gauges.

We’re committed to providing an accurate, safe and reliable fuel level reading, as well as providing you with the highest level of service. Once you have installed magnetic field fuel sensing, your fuel level sensing problems will be solved. When you see the difference, you’ll always choose us for your fuel and liquid level sending needs.
