ABSTRACT:
An apparatus to provide control signals to a line containing a regulating valve for metering predetermined amounts of liquid in which the output of a flow meter is converted to a frequency, the frequency counted in two counters, one of which has been preset with a lead, and the outputs of the counters compared in comparators with a predetermined desired liquid volume, the comparator outputs being used respectively to reduce the flow and then eventually terminate the flow, the reduction and final termination giving a fine metering at the end of the cycle of operation.
