    Abstract: A fluid flow rate and density measuring apparatus is disclosed. The apparatus includes a section of cylindrical conduit, a flow sensor housing for allowing fluid to pass through the open ends of the sensor housing as fluid flows through the conduit, and an elongated cylindrically symmetric structure located within the housing with its longitudinal axis aligned along that of the housing thereby forcing fluid through the annular gap between the exterior of the elongated cylindrically symmetric structure and the interior wall of the sensor housing. The apparatus includes a one-piece construction that includes the housing and the cylindrically symmetric structure. The cylindrically symmetric structure has a length-to-diameter ratio of at least 3:1 and reduces a cross-section area of the conduit to between 20% and 50% of an open inlet area of the conduit.

    Abstract: The pressure differential metering device of the present invention is generally deployed as a flow restrictor placed in the valve inlet so it will create a desired differential pressure to signal a pilot valve, for example, that drives the main valve to limit the flow rate through the valve. The pressure differential metering device of the present invention is deployed across the valve inlet port, with its central axis perpendicular to the direction of fluid flow. The flow restriction element of the present invention may be configured in a variety of sizes to create a desired restrictive cross section to the flow, thereby creating the required differential pressure signals for the valve instrumentation and control. The flow restriction element is configured with upstream and downstream apertures that are the openings to passageways to the corresponding upstream and downstream end-ports. The end-ports provide connection arrangements for the control system of the main valve instrumentation.

    Abstract: An airflow sensor apparatus for measuring flow rate includes a pitot tube with a bypass channel wherein the pitot tube extends halfway into a flow channel in order to reduce a pressure drop. One or more upstream taps can be spaced along the pitot tube facing into a direction of a flow stream which directs the flow to the bypass channel. At least one or more downstream taps can be located to face perpendicular to the direction of flow, such that the fluid after passing over a flow sensor passes through the downstream tap(s). The upstream tap senses stagnation pressure and the down stream tap senses static pressure which is exerted in all directions in the flow channel in order to determine a velocity pressure based on a difference between pressures.

    Abstract: This disclosure relates in general to systems and methods for spot checking flow properties of a multiphase mixture containing one or more hydrocarbons flowing through a pipeline or the like. More specifically, but not by way of limitation, embodiments of the present invention provide systems and methods for creating slug- type flows of isokinetically obtained samples of the multiphase mixture flow. By spot checking the slug-type flow of an isokinetically obtained sample of the multiphase flow, embodiments of the present invention may provide for determining flow properties of gas, oil/condensate and/or water components of the multiphase flow. In certain aspects of the present invention, an active sampling device may be used to enrich one of the phases of the slug -type flow of the sampled multiphase mixture and/or take a representative sample of one of the phases of the slug -type flow of the sampled multiphase mixture.

Erfindungsgemäß werden diese Größen durch einzelne Sensoren, die sich in einer integrierten Einheit befinden erfasst und die von den einzelnen Sensoren erfassten Werte werden anschließend in einer ebenfalls integrierten Recheneinheit verarbeitet. Diese Sensoreinheit gibt an eine nachfolgende Regeleinheit einen Wert ab, der auch schon andere Parameter und/oder physikalische Konstanten berücksichtigt.

    Abstract: A differential-pressure flow sensor for airflow measurement in the presence of water condensation, for use with mechanical ventilators. The pressure-sensing ports at either end of the interfering body are displaced from the inner surface of the surrounding tubing, so as to prevent obstruction of the pressure-sensing ports by free flowing condensed water. The leading edge of the interfering body is angulated so as to deflect airflow towards the pressure-sensing port on the trailing edge of the interfering body, thereby flushing water droplets away from the port. The sides of the interfering body are sloped so as to generate turbulent boundary layer airflow at areas distant from the pressure-sensing ports, thereby encouraging water condensation away from the ports.
