Fluid flow metering method and system
Abstract
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.
