Abstract

A fuel monitoring system comprises a centrifugal air separation chamber having input and output Venturi devices. The system is arranged so that fuel from the fuel tank of the aircraft is pumped to the input Venturi device which due to the pressure drop therein, serves to release air from the fuel before it passes into the centrifugal air separation chamber where the air released from the fuel is separated out and exhausted from the chamber, whereas the substantially de-aerated fuel passes from the separation chamber into the output Venturi device, which produces a pressure drop enabling the vapor pressure of the de-aerated fuel to be determined therefrom.
