FIELD: testing.
SUBSTANCE: invention relates to technical physics, namely, to the field of determining the thermophysical parameters of wet water vapour, and can be used to determine the mass flow rate, degree of dryness, and other parameters of the vapour flow in vapour lines of sources and consumers thereof. Apparatus comprises: a vapour line; in the vapour line, a probe with three channels: a pressure channel in the direction from the flow, a static pressure channel, and a pressure channel in the direction of flow; a meter for the pressure difference between the outputs of the pressure channel in the direction from the flow and the static pressure channel - a dynamic pressure meter; a meter for the static pressure at the output of the static pressure channel; a meter for the pressure difference between the outputs of the static pressure channel and the pressure channel in the direction of flow - a dynamic underpressure meter; a controller for calculating the mass flow rate and the degree of dryness; in order to increase the accuracy of determining the parameters of vapour, the probe comprises: a flat pivot parallel to the axis vapour line, with three holes: one of the holes is the input of the pressure channel in the direction from the flow, another hole is a static pressure receiver at the input of the static pressure channel, and the third hole is the input of the pressure channel in the direction of flow; apparatus also comprises two Pitot tubes: one with a pressure receiver in the direction from the flow is installed through the pivot of the probe at the input of the pressure channel therein in the direction from the flow; the other one with a pressure receiver in the direction of flow is installed through the pivot of the probe at the input of the pressure channel thereof in the direction of flow.
EFFECT: increase in the accuracy of determining the parameters of wet vapour.
