    Abstract: A self-diagnostic measurement method to detect microbridge null drift and performance. An ASIC can be designed to include a self-diagnostic feature that automatically occurs at start up or upon command in Normal Operation whereby the temperature compensated microbridge null can be measured in a state of very low thermal energy and allows for the tracking of microbridge null stability versus time. An Airflow Combi-Sensor ASIC (Heimdal) with its strategic partner ZMD can be developed and can be implemented in the form of a self-diagnostic feature that occurs when power is first applied to the ASIC or upon command. When the self-diagnostic is initiated, power is removed and after the electronics have settled, a small power can be applied to the microbridge to measure the bridge null with reduced sensitivity to flow due to self-heating.

    Abstract: A flow responsive valve for a flow metering system comprising a fluid meter having a minimum measuring flow threshold. The valve is shiftable between an open position at flow rates above the minimum measuring flow threshold, and a pressure pulsating position depending on pressure differential over an inlet port and an outlet port of the valve. The pressure pulsating position alters between a closed position essentially prohibiting fluid flow therethrough at flow rates below the minimum measuring flow threshold, and an open position admitting fluid flow into the supply line at a measurable flow rate above the minimum measuring flow threshold.

    Abstract: A magnetoinductive flow measuring method serves to measure the flow rate of a medium traveling through a measuring tube, while with the aid of at least one field coil a magnetic field is generated with a magnetic field component that extends in a direction perpendicular to the axis of the measuring tube. The electrical resistance of the field coil is measured and the temperature of the field coil, constituting a first temperature, is calculated based on the measured resistance of the field coil. A temperature measurement, constituting the second temperature, is taken at a location other than that of the field coil and the temperature of the flowing medium is calculated on the basis of the first and second temperatures. This provides the user of the flow measuring method an added benefit in that it gives the possibility, in simple fashion, to determine the temperature of the flowing medium. A flowmeter for measuring flow according to the method is also disclosed.

    Abstract: A flow sensor includes sensors connected to a flexible membrane. The sensors detect ambient temperature, pressure, and flow rate of a medium. A method of sensing flow rate includes providing the flexible membrane; coupling the plurality of sensors to the flexible membrane; and detecting ambient temperature, pressure, and flow rate of the medium by the sensors. A flow sensing system includes the flow sensor, an operational amplifier, and a closed loop controller. The sensors are connected in a Wheatstone bridge configuration. The operational amplifier is connected to the Wheatstone bridge and outputs a pressure signal representative of the pressure of the medium. The closed loop controller is connected to the operational amplifier and controls a current through a heating element for a resistor in the bridge such that a voltage across the operational amplifier is substantially zero. The output of the closed loop controller represents the flow rate.

    Abstract: An improved rotary fluid meter is provided having expansion chambers for conditioning pressure pulses that may occur in the flow of fluids. The pressure pulses, which inhibit the meter's ability to accurately measure, may originate from within a metering device or from without it. The pressure pulses may be generated upstream of the meter. Fluid flows into the meter through a fluid flow conduit. At least one flow conditioning chamber which is of such a volume and a shape as to enable it to substantially dampen pressure pulses so as to improve the accuracy of the rotary meter is provided along the fluid flow conduit.
