Preferably, in order to fulfill the function of hydraulic pressure transmission signal, the detection control circuit 400 comprises a switch tube S1, an inductive switch S2 and a delay circuit, in cooperation with the product of the previous patent application. The pressure detection function is activated when water flow is detected.
The tip of water gauge pointer inlays and is equipped with the response metal, inductive switch inlays to be established on the inner wall of water gauge body, and locates the position of the water gauge pointer that has the response metal. The trigger module is a magnet, and the inductive switch S2 is a Hall element. Or, the trigger module is an iron block, and the inductive switch S2 is an eddy current type proximity switch.
