AUTOMOTIVE FUEL FLOWMETRE Russian patent published in 2010 - IPC F02M65/00 G01F3/20 

FIELD: engines and pumps.

SUBSTANCE: automotive fuel flowmetre comprises processor and recorder/indicator, fuel inlet and outlet, graduated vessel with separating element, signaling elements and unions, and hydraulic control valve. Note here that said graduated vessel separating element represents elastic separating membrane with disk-like contact of signaling elements secured along graduated vessel edges. Note also that disk-like contact of signaling devices is located on axis of symmetry of orifices of unions that double as signaling element fixed contacts, and connected to vehicle frame. Hydraulic control valve represents a three-position solenoid valves (TPSV) with their inlets connected to fuel inlet and outlets connected to device fuel outlet. Valve inlets-outlets are communicated with graduated vessel first and second chambers, respectively.
