(b) pump means;
(c) a single meter to measure the quantity of liquid pumped by the pump means;
(d) a plurality of remote dispensing stations;
(e) means to direct the liquid to each dispensing station;
(f) a display associated with and adjacent each dispensing station; and
(g) a control station including control means;
(i) to select and enable any one dispensing station whereby liquid is dispensible at that station;
(ii) and while at the same time, to disable all the other dispensing stations whereby liquid is not dispensible at any of those stations;
(iii) to monitor the single meter;

Abstract
A liquid dispensing system comprises a supply of liquid (121), a pump (101), a meter (161) and a plurality of dispensing points or stations, (181) each controlled by a solenoid valve (201). A control box (281) monitors the meter and controls by electronic apparatus which station is enabled (that is, which solenoid valve (201) is opened) and displays on a display (261) provided a reading derived from the meter. In one embodiment, selection of a station (181) is effected at the control box but the invention also provides electronic apparatus enabling selection to be effected at each station. The invention does away with the need for a meter at each station and finds application in the dispensing of oil or the like in garage workshops.
