FIELD: turbines or turbomachines.
SUBSTANCE: group of inventions relates to determination of phase composition of a fluid medium flow through a turbomachine. Method of determining changes in mass flow rate of fluid flowing into turbomachine includes: (a) controlling turbo machine electric motor supply current variation and (b) applying a known correlation between changes in mass flow rate and current changes, to connect controlled changes with changes of actual mass flow rate of fluid medium into turbomachine. Also disclosed is a method of controlling a valve associated with a turbomachine, a method of detecting turbomachine malfunctions, as well as a control and measuring device for monitoring changes in mass flow rate of fluid flowing into turbomachine.
EFFECT: group of inventions enables to determine phase composition of a fluid medium flowing through a turbomachine.
