The utility model discloses a water tower automatic water supply controller, which comprises a power supply circuit, water level sensor, water level to stop the alarm display circuit, limit stop circuit and the actuator, and is characterized in that the water level sensor is composed of a magnetic float and float rod in the closed, closed float rod with a dry reed pipe in different positions the height of the dry reed pipe top - level control point, stop point to the normal water level of reed middle position, the control point for the low water reed of the position; the water level signal generated magnetic float and the dry reed pipe, the water level signal through the signal line connector connected with the host. The present application may also include a three-phase expansion circuit. The automatic control of water supply in a water tower has been realized because of the adoption of an integrated fully enclosed maglev water level sensor and a three-phase expansion circuit.
