FIELD: engines and pumps.
SUBSTANCE: device for mass calibration of working medium, gas at normal conditions, in electric propulsion system cylinder includes a working medium supply main to the electric propulsion system motors, a measuring line with a pressure sensor installed on it, a normally open shut-off valve and an additional cylinder installed on the measuring line in series between the cylinder of the electric propulsion system and the pressure sensor are inserted, at that, the additional cylinder has a volume in 500…1000 times less than the cylinder of an electric propulsion system, and is equipped with a heating element and a temperature sensor.
EFFECT: ability to measure electric propulsion systems at any time of operation both in space and in terrestrial conditions of the working medium mass.
