​​Cies Inc manufactures universal contactless fuel level senders utilizing our patented Magneto Resistive technology.   While we specialize in aircraft and UAV fuel level measurement, the fact is, that legacy aircraft fuel level measurement relied on a universal fuel level unit from other ground based applications such as farm equipment, marine and heavy equipment.   Equally our magneto resistive senders are finding applications outside the aviation field & our contactless fuel sender technology makes CiES ideal for Propane fuel level applications as well.
