Abstract
Abstract A central control station is used to provide multi-level remote price information to a plurality of multi-grade gasoline dispensing pumps. The control station is reset to zero in coincidence with the completion of transmission of data to the individual pumps. The pumps are interconnected to prevent one pump interfering with the other pump during the transmission of information from the control station to a given pump. Each pump has a first group of decade counters to store the received price information in digital form. A multiplier circuit is provided within each pump including a fuel flowmeter which generates electrical pulses in response to the volume of dispensed fuel and a high frequency pulse generator which pulses a second group of decade counters. The information in the first group of counters is compared in a comparator circuit to the information in the second group of counters. Each time the information in the two groups of counters is identical, the comparator disables the output of the high frequency generator. No additional pulses are transmitted to the second group of counters until another pulse is received from the fuel flowmeter. The same number of pulses which are coupled to the second group of counters is coupled through a decade counter division circuit to an accumulator and read-out device, the final number in the accumulator device being the product of the fuel flow and the price per unit of fuel dispensed.
