Vulcanair P68 Service Bulletin - Digital Fuel Level Digital Fuel Level

Vulcanair P68 Service Bulletin - 

The two new fuel senders are of magnetic field typology and their output is a digital square wave signal whose frequency changes according to the fuel level in the tank.

This new fuel sender uses one wire to interface the level indicator by which it transfers its output frequency to the indicator and a second wire to get a voltage supply, typically  the 28Vdc of the aircraft.


Vulcanair is the second OEM Aircraft manufacturer to utilize the CiES Digital Fuel quantity sender for installation on all of it's aircraft.   

Vulcanair is the first manufacturer to offer a retrofit Service Bulletin Kit to install the system on legacy Vulcanair and Partenavia Aircraft.  

 
AIRCRAFT FUEL GAUGES THAT TELL THE TRUTH 

"With over 10,000 units now flying, CiES has taken over the OEM fuel level sending field.   Our combination of outstanding quality,  reliability, and accuracy has made CiES the standard and the industry leader for fuel level indication on all aviation platforms, GA, Utility, Rotorcraft for both reciprocating and turbine engine applications " 

Britten-Norman Islander Fuel Quantity Senders

Britten-Norman Islander Fuel Quantity Senders  

We just completed a set of Britten-Norman Islander senders for the manufacturer.   

We placed the old Britten-Norman sender design alongside the CiES design for contrast.  Like a lot of small aircraft manufacturers, Britten-Norman had to modify commercial resistance senders to work in their application until we came along.

If you look closely you will see the careful welds on the legacy sender float arm and if you look inside you will see tank sealant applied to the riveted and electrical connections to prevent fuel leakage through the sender body.

The CiES fuel level sender is built for the application, with a custom arm dedicated to this assembly.  Our non contact fuel quantity measurement insures that leakage will not happen through the sender body.  

All of our sensor electronics are fully enclosed in the aluminum housing.  Unlike traditional failure prone senders - our senders have amassed an impressive record of 300,000 hrs of flight time without error or in service replacement.   We will change your opinion of what float fuel senders are capable of - both from a precision and reliability standpoint.

Finally a fuel level sender designed for the aviation market.
