Abstract

PURPOSE: To enable accurate measurement, by taking clean gas for purge as measuring object, in the flow speed detection method for gas including dust by means of pitot tube system using a thermal wire flow meter.
CONSTITUTION: With the valves 8, 9 closed and the valves 7, 10 open, the purge gas flows to the total pressure leading tube 3 and still pressure leading tube 4 to perform gas purge to the tip of the pitot tube 2. Further, the valves 7 and 10 are closed to keep equal the pressure of purge gas remained in the pitot tube 2 and the leading tubes 3 and 4 to the pressure if the liquid in the gas duct 1. After that, when the valves 8 and 9 are opened, the differential pressure caused with the pitot tube 2 causes the flow of purged gas in the measuring tube 22, allowing to measure it with the thermal wire flow speed meter 11 and the thermal wire sensor 12. This flow signal and the signal in proportion to the temperture and pressure of the fluid in the gas duct are inputted to the operation unit 19 to calculate the flow speed of the fluid in the duct.
