Abstract

PURPOSE:To improve the accuracy of rotation detection by providing a driven rotary means coupled magnetically with a driving rotary which rotates through the rotation of an impeller shaft, and detecting the quantity of rotation of the driven rotary means. CONSTITUTION:When the impeller shaft 105 provided with a impeller rotates, the driven magnet 142 rotates following up the driving magnet 141 rotated while reduced in speed to a specific speed reduction rate by the speed reducing means consisting of gears 133, 134, and 138 and a pulse signal corresponding to the rotation of the driven magnet 142 is outputted from corresponding inverters 145a and 145b through the opening/closing operation of reed switches 108a and 108b. An arithmetic circuit 114 computes the flow rate of fluid according to the pulse signal and the flow rate value is displayed on a display part 115.
