DEVICE FOR MEASURING VOLUMETRIC FLOW RATE OF FUEL Russian patent published in 2006 - IPC G01F9/00 

FIELD: measurement engineering.

SUBSTANCE: device can be used for bench tests of liquid duel internal combustion engines. Fuel tank of device is connected with tested engine by pipeline through main three-positioned solenoid-operated valve. Volumetric flow rate is determined from time of emptying of at least one-two-step ancillary vessel, onto any step of which vessel the fuel amount detector is placed. Processes of measurement of filling-in alternate. Speed of filling-in of ancillary vessel is automatically adjusted by means of additional solenoid-operated valve having at least two steps, provided with steps control windings. Input collector and input collector, connected with bottom of ancillary vessel, of additional solenoid-operated valve are connected by nozzles according to number of steps. Main solenoid-operated valve is provided with drive and two windings which are connected with outputs of processor through switches. Control windings of additional solenoid-operated valve are connected with outputs of fuel amount detectors through switches and NOT-AND gates.

EFFECT: improved precision of measurement in wide range; simplified design.
