Aviation's Panel Mount Avionics Installation Leader

Simple, Accurate & Reliable.

Better sensor technology makes float sensors a high technology fuel measurement option. It's just a better way to measure fuel.

Patented Design

Magnetic Field Sensor technology is patented by CiES Inc. for our fuel level senders. These sensors use the basic premise that the electrical properties of certain ferromagnetic alloys, such as permalloy, are influenced by external magnetic fields. This phenomenon can be used to measure angles by including a magnet at the pivot point.

The effect can be thought of as a compass and North is the Float on the surface of the fuel. Like a compass that always points to magnetic North, no matter how you move the fuel - our fuel level sender always points to the float sitting on the surface of the fuel, always.

High Technology Sensor System

The CiES digital fuel quantity system utilizes a high technology sensor system that allows repeatable accurate measurement of fuel in aircraft tank. This high technology and patented sensor system allows fuel measurements down to a change in fuel level to less than 0.03 of an inch. This measurement represents much less than 10ths of a gallon of AVGAS or Jet A. The non-contact measurement method insures a lifetime of operation providing the same consistent fuel level output in the cockpit with modern digital fuel indication.

Floats, arm lengths, and travel angles vary depending on tank dimension and application.

Note: Hardware is NOT supplied with senders. AN, AS, NAS, MS or equivalent hardware is recommended.
