Abstract
An economical liquid metering device which dispenses liquid in digital steps. Further advantages are: the ease of liquid change because components which are in contact with the liquid are economically exchangeable or disposable, and each computer pulse dispenses a predictable quantity of the liquid. To provide a continuous flow, the volume and operation rate between pump pulses may be controlled, so that the dispensing rate becomes substantially continuous.
