| Abstract: | An electromechanical device is described that provides the means for measuring the amount of water consumption from a storage device and for an automatic refill system. The instrument uses three sensing electrodes located in the storage bottle to drive a solid-state Darlington circuit, which, in conjunction with two liquid solenoid valves, controls the operation of the system. |
