A computing unit usable in a system for computing the quantity of fluid A in a mixture of fluids A plus B flowing during selected intervals of time includes: an accumulator for pulses produced by suitable metering means, each pulse representing the flow of a predetermined quantity of a mixture of fluids A plus B (as for example oil and water); the accumulator having an output which represents the total quantity of fluid A plus B flowing during at least one of the intervals; a converter responsive to such pulses repeatedly to digitize an input signal which represents the proportion of fluid A in the mixture, and as a function of pulse reception, there being an output register connected to receive the digitized signal; and an accumulator for the contents of the register to accumulate a digital quantity which represents the net amount of fluid A in the mixture that has flowed from the beginning of that one interval. |
