FACILITY MEASURING PARAMETERS OF GAS FLOW Russian patent published in 2002 - IPC

FIELD: measurement technology, measurement of temperature and pressure of gas flows. SUBSTANCE: facility has ring case housing circular sections leak-tight separated and heat-insulated one from another. Sections form leak-tight central space of facility and temperature transmitters with ring deceleration chambers. Each deceleration chamber houses thermocouple, transmitter of impact and transmitter of static pressure formed by intake holes of pulse tubes. Pulse tubes are fixed tight in holes of wall of central space so that impact pressure transmitter is placed in axial symmetry with inlet hole of chamber and static pressure transmitter is located behind its outlet hole. Thermocouple junction is brought out through wall of central space into ring space of chamber and is located in section between its inlet and outlet holes. Pulse tubes and thermocouples are brought out through central space for connection with recording equipment. EFFECT: enhanced operational reliability of gas transporting equipment. 1 dwg
