A necessity is substantiated to replace RRG-type and similar flow meters in a typical test bench working gas supply system. The replacement is carried out for a new thermal flow meter having no analogs to support unambiguous and exact measurements for main parameters of a thruster providing its thrust efficiency and specific impulse. Descriptions of created flow meter models are presented as well as their parameters and usage recommendations with the test bench to support ground testing of electro rocket thrusters.
