<p>Liquid dispensing systems include a plurality of sources (102, 202) of liquid pumped by pumps (104, 204) each with a single metering pump and each to a plurality of remote dispensing stations (109, 209) via conduits (110, 210) under the control of a control station (301). The control station (301) can select and enable any one of the remote stations (109, 209) whilst disabling all other remote stations (109, 209) from dispensing that particular liquid (102) but allowing dispensing of another liquid (202), monitor each of the flow meters and produce a display at the dispensing station (109, 209) of the volume of liquid (102, 202) which has been dispensed at that station, effect zero readings at all other dispensing stations for that liquid, and produce a display of dispensed liquid at the control station (301). <IMAGE></p> |
