速測定装置。[Claims for Utility Model Registration] (1) The end of a tubular main body 1 having a hole 1a in its axis is closed with an elastic body 2, and the elastic body 2 is capable of swinging around the end of the main body 1 as a fulcrum. A lead wire is embedded in one end of the baffle plate 3 and extends to the outside through the axial hole 1a of the main body 1 on the stretch side and compression side surfaces of the elastic body 2 that expands and contracts as the baffle plate 3 swings. A flow rate measuring device characterized in that at least one of strain gauges 6 and 7 connected to a strain gauge 5 via a strain gauge 4 is attached. (2) A hollow airfoil-shaped measuring section 12 made of an elastic material is fixed to one end of the tubular shaft 11, and the tubular shaft 1 is attached inside the left and right side surfaces of the measuring section 12.
Strain gauges 6 and 7 connected to the strain gauge 5 via lead wires 4 extending outside through the inside of the shaft 11 are affixed thereto, and adjustment is performed to adjust the orientation of the measurement unit 12 with respect to the fluid at the other end of the shaft 11. Lever 1
5. A flow rate measuring device characterized by comprising: (3) Hollow airfoil-shaped measurement part 1 made of elastic material
2, pressure sensitive plates 18, 1 are installed in holes provided on the left and right side surfaces of the hollow airfoil-shaped measuring section 17 made of a rigid material.
The flow rate measuring device according to claim 2, wherein the pressure sensitive plates 18 and 19 have strain gauges 6 and 7 attached to the inner surfaces thereof.
