ABSTRACT:
A system for metering the volume of a liquid, e.g. ink, supplied by a positive displacement pump to an installation, such as a printing press, employs a device for generating a first series of signals each indicative of completion of a pumping stroke. The speed of the pump is also sensed to generate a second series of signals each indicative of the positive supply of liquid by the pump. The signals of the first series are counted only in the presence of a corresponding signal of the second series. The result is an accurate numerical indication of the total volume of liquid pumped.
