As seen in Publication No. 11008, multiple levels of weirs with different heights were installed, and excess or deficiency in the amount of water supplied was detected and displayed based on the height of the weir that water overcame during water supply. However, it was not possible to detect the amount of water supplied steplessly, and it could only be used to indicate excess or deficiency in the amount of water supplied, but could not be used at all for automatic control of the amount of water supplied or the water level.

に形成する。 The detector 10 has a light emitting element 11 and a light receiving element 12 arranged facing each other on both sides of the constriction part 9 of the water supply passage 7, and the light receiving element 12 receives the light from the light emitting element 11 that has passed through the water supply passage 7. However, the output voltage V 0 changes depending on the amount of light received. In addition, each element 11,
At least the wall of the water supply passage 7 facing the water supply passage 12 is formed into a transparent wall.

なく、出力電圧V0は小さくなる。 In the above configuration, if the water supply control valve 8 is now opened to start water supply, the water flowing through the water supply passage 7 will cause a vortex change downstream of the throttle valve 9. This vortex change is greatly affected by the water flow rate, that is, the amount of water passing through a unit cross-sectional area per unit time.When the water volume is small, vortices are difficult to generate, whereas when the water volume is large, irregular vortex changes occur. occurs. The more irregularly the vortices are generated, the more bubbles will be generated, and these bubbles will diffusely reflect the light from the light emitting element 11. Therefore,
As the amount of bubbles generated increases, the amount of light received by the light receiving element 12 decreases, and the output voltage V 0 decreases.

きる。 FIG. 3 is a diagram showing temporal changes in the output voltage of the light-receiving element, and the output voltage V 0 becomes stable after a certain amount of time has passed after the start of water supply. Therefore,
Output voltage after a certain period of time from the start of water supply
By detecting V 0 , it is possible to determine, for example, whether the amount of water supplied is excessive or insufficient based on the value. Now, assuming that the voltage value at the time of proper amount is Vs, if the output voltage is A, it can be determined that there is insufficient water supply, and if the output voltage is B, it can be determined that there is excess water supply.

により給水を停止するようにすればよい。 In addition, when automatically controlling the amount of water supply, it is sufficient to determine whether the amount of water supply is excessive or insufficient based on the output voltage V 0 of the light receiving element 12, and to control the opening/closing degree of the water supply control valve 8 based on the determination result. In addition, when automatically controlling the water level, the water supply amount is determined based on the output voltage V 0 of the light receiving element 12, the time required to supply water to the specified water level is calculated based on the water supply amount, and the water supply is controlled based on the elapse of this time. All you have to do is stop it.
