A Deceptively Simple, Accurate & Reliable way to Measure Fuel  


Better sensor technology makes float sensors a high technology option.    



Magnetic Field Fuel Level SENDER 


A better way to measure fuel


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.


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, always.


The Video illustrates the basic technology we utilize to build quality fuel level senders.
