A vessel designed for enclosing at least one sensor is arranged within a fuel tank. The vessel is provided with a fuel inlet connected to a refuelling arrangement of the tank, and with through-holes for the fuel to exit the vessel to the tank or to enter the vessel from the tank. It allows that measurement results which are provided by the sensor during a refuelling operation relate to the fuel currently admitted into the tank, separately from the fuel initially contained in the tank before the refuelling operation has started.

Vessel for enclosing at least one sensor within a fuel tank

A fluid gauging system includes a set of fuel level probes and two computation modules adapted for inferring fluid level information based on measurement signals which originate from the probes. In a refuelling operation mode, the probes are distributed into two dynamically configurable subsets, which are separate and assigned respectively to the computation modules for deriving two results for the fluid level independently from each other. Such system has special interests for fuel tank equipment designed for aircraft. A major advantage is a reduction in the total number of fuel level probes which are necessary to obtain reliable results whatever the fuel level and the aircraft attitude and acceleration.
