Dispensing apparatus and weighing process with control unit

摘要

Dispensing apparatus (1) has a platform (2) for receipt of a container such as a wine glass (8). The platform (2) is connected to a transducer (3) which is sensitive to weight on the platform (2) and which produces an electrical signal dependant on the magnitude of that weight. Electrical outputs from the transducer (3) are connected to a control unit (4) over connections (14). The control unit (4) includes a keypad (12) and a display 13. Control signals from control unit (4) are supplied over electrical connections (14) to a solenoid valve (6). The control unit (4) controls the flow (11) of material by opening and closing solenoid valve (6).
