As a result, the permanent magnets 112 to lid also rotate, and this rotation is transmitted to the slit plate 7 via the rotating shaft 9, and the rotation of the slit plate 7 blocks the optical path at the sensor 8 section. As a result, the rotation of the rotation shaft 9, that is, the output shaft 2, is detected by the sensor 8, and is outputted from there as a flow rate pulse signal to the control device 18.
The control device 18 calculates and calculates the flow rate pulse signal and outputs it as a flow rate to the display meter 19 and displays it here, and the signal line 20

伝導効率が向上する。In addition, in the above embodiment, the power generation coil 14 was arranged between the permanent magnets 5a to 5d and lla to lid of the magnetic compression ring, but the power generation coil 14 is not necessarily limited to the above-mentioned power generation coil 14. As a second embodiment, as shown in FIG. 3, a thin flat coil 21 (for example, a printed coil) can be used in place of the power generation coil 14. In this case, a permanent magnet 5a of magnetic force/knob ring can be used. ~
Since the distance between 5d and lla to lid is shorter than when the power generation coil 14 is used, the conduction efficiency of the magnetic coupling is improved.
