Abstract:
1. An apparatus for use in sensing one or more properties of a fuel, comprising: a tube extending along a longitudinal axis, said tube having a hollow interior defining a fuel passage between a fuel inlet and a fuel outlet; first and second sensing plates being disposed radially outwardly of said tube on an outer surface thereof so as to leave said fuel passage unobstructed, wherein said sensing plates comprise electrically-conductive material; an electrical circuit configured on a printed circuit board (PCB), said circuit being electrically coupled to said sensing plates and configured to generate an output signal indicative of the one or more properties of said fuel; a shield comprising electrically-conductive material configured to reduce electromagnetic interference (EMI); and a generally U- shaped channel member having a base and a pair of legs extending from said base and configured to received said tube, said channel member having a width between said legs so as to form a pair of pockets between inside surfaces of said legs and said tube, each pocket being configured to receive a respective one of said sensing plates.
