Abstract
PURPOSE: To obtain the flow rate sensor less in power consumption, by providing magnet to the operation member shaken in following to the cam member rotated in proportion to flow rate, and detecting the static capacitance of the static capacitance unit having the magnetic member absorbed with this magnet.
CONSTITUTION: The cam 32 is inserted to the output rotating shaft 31 rotated in proportion to the flow rate of fluid, and the operation member 33 having the magnet 332 and projection 331 at the tip is coupled with the cam 32. Further, the static capacitance unit is constituted with the moving electrode 35 having the magnetic substance 351 opposing to the magnet 332 and with the fixed electrode 36. When the cam 32 rotates and the projection 331 of the operation member 33 is fallen to the lower part 321 of the cam 32, the magnet 351 of the moving electrode 35 is absorbed with the magnet 332, the distance between the moving electrode 35 and the fixed electrode 36 is changed, resulting that the static capacitance is changed. The electric signal in proportion of flow rate can be obtained by detecting this change at the detection circuit 39.
