Abstract

PURPOSE:To make the accurate and quick measurement of the speed, direction and static pressure of fluid possible with simple constituion by providing fluid in-flow through-holes into the respective chambers isolated by means of piezoelectric element plates of a cylindrical case in the positions symmetrical with the 1st through-hole. CONSTITUTION:Four chambers 2-5 isolated by means of piezoelectric element plates 9-11 are provided to a cylindrical case 1, and a fluid inflow through-hole 6, and fluid inflow through-holes 7, 8 respectively symmetrical to the hole 6 are provided to each of the chambers 2-4 and a fluid inflow port 20 is provided in the bottom part 13 of the chamber 5 as well. If this case 1 is immersed in fluid, and is disposed in such a way that there are no dynamic pressure differences between the element plates 10, 11 of the chambers 3, 4, fluid speeds are measured from the dynamic pressure through the element 9 of the chamber 2 and the directions of fluid are measured according to the directions of the hole 6 of that time. On the other hand, static pressure is determined through the element 11 by the fluid flowing into the chamber 5, thus with the simple constitution, the speed, direction and static pressure of the fluid are measured accurately and quickly.
