Abstract: A system is disclosed which includes a flow meter producing voltage pulses of a frequency proportional to the flow rate of a flowing mass, and a sensing element responsive to a physical condition of the flowing mass with circuitry which produces a D.C. voltage signal analogous to that condition. A generator provides linear sawtooth voltage pulses against which a comparator circuit compares the analog voltage from the sensing element and circuit. The voltage resultant of the comparison passes a portion of the voltage pulses from the flow meter to a divider circuit element and a subtractor circuit element of the system for conversion of relatively low order changes in the physical condition to an expanded range equivalent, and for correction of the flow rate or volume as a function of such changes. The flow rate or volume as thus corrected is registered on a suitable flow rate indicator or volume counter.

Abstract: A system is disclosed in which a source and detector of radiation are positioned to sense a physical property, the detector generating electrical pulses proportional to the energy of the source impinging thereupon. The circuitry of the system amplifies and shapes the pulses, converts them into an analog D.C. signal with A.C. components proportional to the frequency of the pulses, and amplifies the D.C. through A.C. and operational amplifiers to cancel the A.C. component and produce a pure analog D.C. output signal.

Abstract: A system which includes a flow meter producing voltage pulses of a frequency proportional to the flow rate of a flowing mass, and a sensing element responsive to a physical condition of the flowing mass with a circuit which produces a DC voltage signal analogous to that condition. A generator provides linear sawtooth voltage pulses against which a comparator circuit compares the analog voltage from the sensing element and circuit. The voltage resultant of the comparison switches a portion of the voltage pulses from the flow meter to a divider circuit element and a subtractor circuit element of the system for conversion of relatively low order changes in the physical condition to their full range equivalents, and for correction of the flow rate or volume as a function of such changes. The flow rate or volume as thus corrected is registered on a suitable flow rate indicator or volume counter.
