DEVICE FOR MEASURING MAGNITUDE AND DIRECTION OF FLOW VELOCITY VECTOR COMPONENT IN SELECTED PLANE Russian patent published in 1994 - IPC

FIELD: measurement technology. SUBSTANCE: device has a group of outer deflectors for entrapping a gas and directing it into the area of location of a circulation chamber by rectangular-in-cross-section nozzles, a measuring module including a plate upon which a gas flow pressure acts in the circular chamber. The plate comprises a flexible member deformable under the action of gas flow pressure with resistance strain gauges stuck on it. The plate can be made in the form of a flag back portion of which is rounded off, in the front portion adjacent to the rest and in the back portion through holes being formed. EFFECT: enhanced accuracy. 2 cl, 6 dwg
