WIRELESS AUTOMATIC WATER-LEVEL CONTROLLING APPARATUS

摘要

PURPOSE: A wireless automatic water-level control apparatus for a water tank is provided to accurately control the operation of a pump located in a deep well through combined application of high and low water levels based on an angle sensor. CONSTITUTION: A wireless automatic water-level control apparatus for a water tank comprises a deep well(110), a water pipe(120), a water tank(130), a pressure sensor(140), an angle sensor(150), and a water level control unit(160). The deep well comprising a pump is installed to collect subsurface water. The water pipe is connected to the deep well on the inlet to deliver the collected subsurface water and equipped with a check valve(121) for preventing the backflow of the subsurface water. The water tank receives the outlet of the water pipe and stores the subsurface water transferred. The pressure sensor is arranged between the check valve and the outlet of the water pipeline. The angle sensor is arranged in the outlet of the water pipe and connected to a ball tap(151) to detect the angle corresponding to the water level at which the ball top is located. The water level control unit controls the operation of the pump and displays the pressure detected by the pressure sensor or the amount of water stored in the water tank.
