ABSTRACT:
A dispensing system for metering precise quantitites of liquid to a use site in droplet streams. The system includes a reservoir containing a quantity of liquid to be dispensed, a droplet generator for producing a stream of uniformly sized droplets of the liquid in the reservoir; and a device for controlling the droplet generator to produce a droplet stream containing a predetermined number of droplets. The control device can include an operator-settable counter for selectively varying the quantity of dispensed liquid by adjusting the number of produced droplets or by adjusting the size of droplets comprising the droplet stream.
