ABSTRACT:
A net oil computer including a differential pressure unit and a turbine or positive displacement flowmeter. The flowmeter produces output pulses at a frequency directly proportional to the rate of volume flow through a pipeline. The output of the flowmeter is impressed upon the pole of a single-pole, double-throw electronic switch. One switch contact is connected to an indicator through a divider, a driver amplifier and a counter. The other contact is also connected to an indicator through a divider, a driver amplifier and a counter. The switch is operated by a gate generator connected from the differential pressure unit.
