摘要:
A separation type multiphase flow meter apparatus (10) comprising a separation module (18) arranged to at least partially separate a multiphase stream comprising water, hydrocarbon liquid and hydrocarbon gas into a first sub-stream comprising a gas fraction and a second sub-stream comprising a liquid fraction. The apparatus comprises a first metering dev ice (16) for measuring the flow rate of the first sub-stream, and a second metering device (17) for measuring the phase fraction and the flow rate of the second sub-stream, wherein the second metering device is arranged to measure the water-in-liquid ratio (WLR ) of the second sub-stream, wherein the apparatus is arranged to use the WLR measured by the second metering device as a measure also for the WLR of the first sub-stream, and wherein the cross-sectional flow area of the first metering device is larger than the cross-sectional flow area of the second metering device.

摘要:
Die Erfindung betrifft Luftmassenmesser mit einem Gehäuse welches einen Luftführungsweg aufweist in dem ein Luftmassensensorelement angeordnet ist, wobei das Luftmassensensorelement auf einem Sensorelementträger angeordnet ist, der im Gehäuse des Luftmassenmessers angeordnet ist und der mit Anschlussdrähten mit einem Schaltungsträger elektrisch verbunden ist, wobei der Schaltungsträger ebenfalls im Gehäuse des Luftmassenmessers angeordnet ist. Um einen Luftmassenmesser mit einem Sensorelement anzugeben, bei dem das Luftmassensensorelement auf einfachen und kostengünstige Art und Weise hochgenau im Luftführungsweg positioniert ist, ist am Gehäuse des Luftmassenmessers ein Positionierungselement ausgebildet, das in einen Positionierungselementaufnahme eingreift, welche im Sensorelementträger ausgebildet ist, wodurch das Luftmassensensorelement im Luftführungsweg präzise positioniert ist.
摘要:
Apparatus features a signal processor or signal processing module configured to: receive signaling containing information about a central air-core of an overflow pipe of a hydrocyclone where fluid flow is concentrated in an outer annular region of the overflow pipe that is against an inner wall of the overflow pipe during a normal operation of the hydrocyclone; and determine corresponding signaling containing information about a collapse of the central air-core of the overflow pipe of the hydrocyclone during an abnormal oporation of tho hydrocyclone, based upon the signaling received. The signaling contains information about a fluid flow rate of the fluid flow by detecting a change in the magnitude of a force and/or a moment on the probe.
摘要:
A flow sensing module is provided for determining a flow rate of a fluid flowing through a flow channel. The flow sensing module may include an integrated flow restrictor, sometimes including a plurality of concentric ribs defining a plurality of orifices shaped to match the curvature of the wall of the flow channel. A first sensing port may open into the flow channel upstream of the flow restrictor, and a second sensing port may open into the flow channel downstream of the flow restrictor. A flow rate of a fluid flowing through the flow channel may be determining using a differential pressure between the first and second ports created by the flow restrictor, either using a flow sensor or a pressure sensor. The particular arrangement and relative dimensions of the orifices of the flow restrictor and the pressure ports can result in substantially reduced noise.

The disclosed embodiments include a mass flow controller for controlling a flow of a fluid. In one embodiment, the mass flow controller comprises an inlet for receiving the fluid; a flow path in which the fluid passes through the mass flow controller; a mass flow meter for providing a signal corresponding to mass flow of the fluid through the flow path, the mass flow meter having a bypass through which a majority of fluid flows; a turning vane positioned upstream of the bypass for generating a more uniform fluid flow; an adjustable valve for regulating the flow of the fluid out of an outlet of the mass flow controller; and a controller configured to apply a valve control signal to adjust the adjustable valve to a desired valve position to control the flow of the fluid out of an outlet of the mass flow controller.
