A flow meter device includes: an inlet portion, into which a fluid flows; an outlet portion, from which the fluid flows out; a plurality of measurement passage portions provided parallel to each other between the inlet portion and the outlet portion; and at least one flow rate measurement unit, each flow rate measurement unit being configured to measure a flow rate of the fluid that flows through a passage in a corresponding one of the measurement passage portions Shapes of passages in the respective measurement passage portions coincide with each other The plurality of measurement passage portions include: the one measurement passage portion(s), which is/are each provided with the flow rate measurement unit; and the other measurement passage portion(s), which is/are not provided with the flow rate measurement unit

Flow meter device

A retractable flow conditioner that includes a body adapted for insertion into a fluid in a confined conduit upstream of a differential pressure measuring probe. The body has at least one flow conditioning element. The retractable flow conditioner also includes a mounting assembly attached to the body. The mounting assembly is configured to retractably mount the body into the confined conduit.

A multiphase flow measurement insert for insertion within a pipe includes a first, upstream isolation disc sized and shaped so as to make a fluid tight seal with the interior surface of the pipe. A second, downstream isolation disc is also sized and shaped to make a fluid tight seal with the interior surface of the pipe. The first isolation disc includes a first orifice and the second isolation disc includes a second orifice. The lower edge of the first orifice is positioned vertically higher in the first isolation disc than the lower edge of the second orifice in the second isolation disc. A measurement vessel extends from the first orifice to the second orifice forming a flow channel that is downwardly sloping when the multiphase flow measurement insert is in its operational orientation.

A conditioning accumulator (2) for use in a multiphase flow measurement system. The conditioning accumulator includes a container which has an inflow orifice connected to the end of an inflow pipe and an outflow orifice connected to the end of an outflow vessel. The lowest point of the inflow orifice is positioned at or near the bottom of a sidewall of the container. The outflow orifice is positioned in a sidewall of the container, where the lowest point of the outflow orifice is vertically offset and above the lowest point of the inflow orifice when the container is in an operational orientation. The container includes a phase distributer located next to the inflow orifice adapted to distribute the liquid and gas phases of the incoming flow from the inflow pipe within the container. An exit flow resistance device reduces/ resists the outflow of liquid from the container.

A stratified flow multiphase flowmeter

A device and method for conditioning media flowing within a conduit enabling sensors placed within short straight run distances to measure media flow with improved accuracy employing a thermal flow instalment. A flow conditioner downstream of a media flow measuring transducer has walls that diverge in the flow direction to optimize readings of the media flow from the transducer.
