A flow conditioning assembly comprising an integral elbow flow conditioner and a downstream flow conditioner. The elbow flow conditioner includes a pipe elbow with one or more flow conditioning elements. Each flow conditioning element includes one or more turning guides. Each turning guide is generally circular and radially spaced from one another and an inner surface of the elbow. Spaced vanes maintain the radial spacing of the turning guides. The vanes divide the radial space between the turning guides and pipe elbow into a plurality of flow channels that turn in generally the same direction as the inner surface of the pipe elbow. The downstream flow conditioner comprises a flow conditioning structure within a pipe element. The flow conditioning structure includes one or more flow guides of generally circular form radially spaced from one another and the pipe element. Spaced support vanes maintain the radial spacing of the flow guides.

An orifice module for a flow switch system has a cylindrical body which is symmetric about a central axis which defines a metering orifice. An axial central hub holds the stem. The hub connects to the cylindrical body by at least three support spokes which forms a plurality of flow channels angularly disposed about the central axis. The module interacts with the flow switch to enhance the function of the flow switch and also reduces turbulence in the fluid flow system.

A fluid flow modifier device comprising: an inlet portion for receiving a flow of fluid; an outlet portion for outputting the flow of fluid; and a flow modifier portion disposed between the inlet portion and the outlet portion, the flow modifier portion comprising an outer portion comprising a closed cross-section to the flow of fluid and an inner porous portion configured such that at least a portion of the flow received in the inlet portion must pass through the inner porous portion to reach the fluid outlet. The fluid flow modifier device is ideally used to transition fluid flow between an fluid supply line and a fluid treatment zone—for example, a pressure water supply line and an ultraviolet radiation treatment device (e.g., drinking water treatment device).

A fluid pipe device is provided, which includes a pipe member forming a flow channel for flowing a fluid; a heating member for generating heat to heat the pipe member; a metal heat transfer member abutting against the heating member and conducting the heat to the pipe member; and a terminal member electrically connecting the heating member and the heat transfer member. The heat transfer member includes a first heat transfer member and a second heat transfer member, and at least one of the first heat transfer member and the second heat transfer member forms the terminal member at one portion, and the first heat transfer member is provided in the pipe member in such a way as not to be exposed inside the flow channel of the pipe member.

A connection device, for mechanical ventilation and monitoring of spontaneous breathing of a patient (P), includes a fluid-guiding unit (9, 11, 15) and establishes a fluid connection between a medical arrangement (100) and a patient-side coupling unit (19). A volume flow sensor (90) measures an indicator of volume flow of fluid through the fluid-guiding unit. A volume flow sensor component (2) engages with an interior of the fluid-guiding unit. A homogenization unit (10) is nonrotatably inserted into the interior between the patient-side coupling unit and the component and includes two sieves and a connection element, which connects the sieves together. The homogenization unit homogenizes the flow of fluid through the fluid-guiding unit. An inner profile of the fluid-guiding unit and an outer profile of the homogenization unit together form a mechanical coding, which determines a defined rotation position of the homogenization unit in relation to the fluid-guiding unit.

A guide element for hydraulic fluid includes a first end surface, a second end surface, and an exterior surface connecting the first end surface to the second end surface. The first end surface includes a first chamfered opening. The second end surface includes a second opening that fluidly communicates with the first opening to define a longitudinal bore that includes a tapered section. The first chamfered opening and the tapered section are configured to guide the hydraulic fluid to facilitate transformation of a turbulent flow of the hydraulic fluid into a laminar flow of the hydraulic fluid.

Implementations of an orifice plate configured to regulate a fluid flow are provided. An example orifice plate is configured to be positioned in a conduit and comprises a plurality of holes that extend therethrough. The plurality of holes are arranged to form one or more spiral layouts configured to regulate a fluid flow passing therethrough. Each spiral layout is a logarithmic spiral. In some implementations, each spiral layout has a growth factor of substantially 1.618 for each quarter turn. In some implementations, each hole in an orifice plate has a contoured conical shape extending between an inlet and an outlet, the inlet is larger in diameter than the outlet.

A flow modifying device comprises an outer shell, a central tube within an interior space of the outer shell, and a plurality of helix vanes within the interior space. The central tube extends along at least a portion of a length of the outer shell. Each of the helix vanes extend along the outer shell and along the central tube. An outer edge portion of each of the helix vanes is attached to the outer shell and an inner edge portion of each of the helix vanes is located within a central passage of the central tube. In this manner, a first portion of each of the helix vanes extends between the outer shell and the central tube and a second portion of each of the helix vanes is located within the central passage of the central tube.

The invention provides a gas flow metering gas chamber and a gas flow meter. The gas flow meter includes the gas flow metering gas chamber, a display device and a housing. The gas flow meter gas cell includes a cavity, a gas inlet, a gas outlet, two ultrasonic transducer mounting holes and a reflection device. The signal emitted by the first ultrasonic transducer installed in the first ultrasonic transducer mounting hole and the signal emitted by the second ultrasonic transducer installed in the second ultrasonic transducer mounting hole intersects with each other to form an L-shaped reflection passage. Compared with V-shaped, W-shaped, and N-shaped reflection structures, the effective distance between the two ultrasonic transducers of the present invention more is increased, the cross section of the cavity is reduced, and the rate of the gas flow is increased, which avoids contamination contained in the measured gas to contaminate the ultrasonic transducers and thereby improves the measurement accuracy.

A flow conditioner includes a group of flow conditioning units including a first flow conditioning unit and a second flow conditioning unit. The flow conditioner also includes a mixing space for developing a flow. The mixing space is located between the first and second flow conditioning units. One of the first or second flow conditioning units can include one or more of a shaper or a reducer, and the other of the first or second flow conditioning units can include one or more shapers.
