ABSTRACT:
Disclosed are apparatus and methods for determining the actual, standardized volume of fluid flowing in a flowline. A flow meter in the line measures volume and provides the measured value in the form of a pulse train. Compensating means change the member of pulses in the pulse train as required to compensate for the difference between the actual fluid temperature and a standard reference temperature. The pulse train is also compensated to correct for meter error. Digital verification means are provided for verifying that the compensating means are working properly. In the methods, an input counter connected to the input of a circuit in the system is gated to start counting pulses applied into the circuit while an output counter is simultaneously gated to start counting the pulses out of the circuit. At the end of the test period, the input and output counts and other known input values are employed as the variables in a mathematical equation representing the circuit function. Balancing of the equation using these variables verifies that the circuit is operating correctly. The method and apparatus may be employed to verify proper operation of other digital computing circuits or to establish a comparative relationship between a plurality of electrical pulse train producing means.
