SELF-FILL SYSTEM

摘要

The system includes a sensor member disposed in the tank in a position so as to be responsive to the rise and fall of liquid in the tank. A pump is provided to pump syrup into the tank. Water controller is also provided such as a water solenoid valve for controlling water flow to the tank. The sensor member comprises probes which include a low probe for detecting a low predetermined level of liquid in the tank and a high probe for detecting a high predetermined level of liquid in the tank and adapted to respectively generate low and high probe signals. A controlling circuit is used in response to the flow and high probe signals for controlling the pump and water fill valve.
