CAPACITANCE-TYPE LEVEL GAUGE Russian patent published in 2015 - IPC G01F23/26 

FIELD: measurement equipment.

SUBSTANCE: proposed invention relates to capacitance-type gauges used as a fuel detector to detect the amount of fuel remained in a fuel tank. Capacitance-type level gauge (15) includes a column-shaped inner housing (27) from a dielectric material; hollow cylindrical outer housing (23) from a dielectric material, which is arranged outside the circle of inner housing (27) in its circumferential direction and at some distance from it; internal electrode (29) attached to the outer circular surface of inner housing (27); and external electrode (25) attached to the inner circular surface of outer housing (23). The proposed capacitance-type level gauge (15) measures electric capacitance between internal and external electrodes (29, 25) and detects level of the fuel contained between internal and external electrodes (29, 25). Outer housing (23) is provided with a group of external through holes (31) allowing an electric charge to be moved from its outer circular surface to external electrode (25).

EFFECT: suppression of electrostatic charging at operation of the gauge at its being used in a dielectric housing.
