ABSTRACT:
A water level detector and indicator system includes a water level detector and a water level display controlled by the water level detector to give a respective output signal when the level of water changes from one position to another. The water level detector can be a mechanical type which uses a float to control a multi-step switch causing a series of indicator lamps to give light respectively. The water level detector can be an electronic type which uses metal probes to detect the change of water level, and a controller driven by the metal probes to control buzzers and indicator lamps to work.
