Abstract
An electronic totalizer having a non-destructive readout indicative of the time-integrated total of a process variable such as flow rate, metered by a transducer whose output signal lies within a predetermined current range. In the totalizer, the transducer signal is converted into a proportional voltage signal that is applied to a voltage-to-frequency converter yielding pulses at a rate which varies with the magnitude of the voltage signal, the pulse frequency being high at the upper limit of the range. The converter pulses are fed to an adjustable scaler yielding output pulses at a scaled-down rate appropriate to the desired unit of measurement, these being applied to a counter which gives a totalized reading. By setting the scaler, one may establish a reading in useful increments of process flow, such as gallons or liters.
