    Abstract: A FLUID FLOW METERING METHOD AND SYSTEM USING DIGITAL SIGNALS AND LOGIC FOR PRODUCING A COMPENSATED MANIFESTATION OF FLUID FLOW BY THE MATHEMATICAL MULTIPLICATION OF TWO OR MORE SENSED PARAMETERS, ONE PARAMETER BEING A FLUID FLOW RATE AND THE OTHER ONE OR MORE PARAMETERS BEING RELATED TO A CONDITION OF THE FLUID SUCH AS ITS CONSTITUENCY, PRESSURE, DENSITY, DIELECTRIC CONSTANT, TEMPERATURE OR THE LIKE, WHERE THE PARAMETERS ARE REPRESENTED BY SERIES OF ELECTRICAL PULSES. THE DIGITAL OUTPUT SIGNAL PULSES OF THE FLOWMETER ARE RELATED TO FLUID FLOW, AND ARE USED TO GATE PACKETS OF HIGH FREQUENCY PULSES FROM A TRANSDUCER. THE DURATION OF THE PULSE PACKET IS DESIGNED TO BE LESS THAN SPACING BETWEEN TWO ADJACENT FLOW PULSES AT MAXIMUM FLOW RATE, AND THE EXACT NUMBER OF HIGH FREQUENCY PULSES IN EACH PACKET IS RELATED TO THE CONDITION OF THE FLUID AS SENSED BY THE TRANSDUCER.

    Abstract: Method and apparatus for compensating a digital nuclear densometer for decay in the intensity of the radiation source, drift and instability of the detectors, temperature and other factors. A common source of radiation is used to irradiate separate detectors through substances of known and unknown density and a ratio between the number of pulses in the output signals of the detectors taken to compensate for conditions common to both detectors. The detectors are energized by a common source to minimize drift and instability and a circuit is provided for digitally linearizing the relationship between the number of pulses in the output signal and the density of the substance under investigation.
