Filed: 1972-05-17
Abstract: 1386877 Metering fluid flow; price x quantity calculations BENNETT PUMP Inc 17 May 1972 [8 Dec 1971] 23123/72 Heading G4D [Also in Division G1] In indicating the quantity and total price of a flow of petrol, a flow responsive transducer produces gaps in a train of pulses generated by an oscillator and the gaps are detected by a pulse width discriminator and counted to indicate quantity, and an adjustable preset number of the oscillator pulses is accumulated in a counter in response to each detected gap to indicate total price. As described, a light-emitting diode 4 and photo-transistor T1 co-operate with a perforated disc 6 rotated by the petrol flow to block a semi-conductor oscillator once for every <SP>1</SP>/ 100  gallon. The oscillator may be as shown in Fig. 3 or a ring counter (Fig. 2, not shown) and should generate at least 999 pulses between consecutive blockings for the fastest flow rate. The gaps are detected by a pulse width discriminator (Fig. 5, not shown) which opens a latched gate to pass oscillator pulses to the price counter and also passes a pulse to the volume counter. Three decades of the unit price are set on binary coded selectors (B1, B10, B100, Fig. 6, not shown) for comparison with a binary coded decimal count of the oscillator pulses, the latched gate being disabled at coincidence. The comparators comprise a bank of exclusive OR gates.
