FIELD: physics.
SUBSTANCE: method of determining dryness of wet steam involves measuring pressure in a controlled stream of steam. A steam sample is then collected from the controlled stream, the collected sample is throttled into a flow chamber and calculations are carried out based on the measured parameters. The collected steam sample flows from the first flow chamber into a second flow chamber. Both chambers are placed in the controlled stream of steam or other heating medium. Pressure and temperature is measured in each chamber. After the second chamber, flow rate, pressure and temperature of the collected sample is measured. The value of flow rate is then established based on parameters measured in the first chamber.
EFFECT: determining dryness of a stream of wet steam without condensing the collected sample.
