Abstract

PURPOSE: To measure the flow speed of the fluid to be measured and enable the stable measurement for a long period by detecting the air pressure inside both pipes for measuring the total pressure and static pressure having air-jetting prifices respectively in the parallel and rectangular directions to the flow of the fluid.
CONSTITUTION: The air under the required pressure is setn into both pipes 3 and 4 for measuring the total and the static pressure and is jetted out from the jetting orifices 5 and 6 of both measuring pipes 3 and 4 into the flow of the fluid 2 to be measured, i.e. from the total-pressure measuring pipe 3 it is jetted out in parallel to the direction of the flow of the fluid, while from the static-pressure measuring pipe 4 at right angle to the direction of the flow thereof. And, by measuring the difference in the voltage on the secondary side of orifices 12 and 13 in both measuring pipes 3 and 4, the flow speed of the fluid 2 is measured. In addition, the jetting orifices 5 and 6 are free from filling with solid substances in the fluid 2 since the air is jetted out therefrom, and thus the stable measurement for long period can be secured.
