Abstract: A flow meter includes a meter body having a longitudinal axis and including a fluid passageway and an outer surface, and a plurality of electronics housings supported on the meter body by a mounting member, wherein the mounting member includes a base, a tubular member having a passage extending therethrough for the passing of a transducer cable, and a bracket member coupled to the tubular member distal the base, the bracket member having a pair of elongate slots, each configured to allow for the passage of a transducer cable to one of the electronics housings.

Abstract: A Fluid turbine flow meter, including a measurement chamber, a turbine body that is displaced axially, as a function of the fluid flow rates, between a high position and a low position in the measurement chamber and having a rotation axis, a centering bearing for the rotation axis in the measurement chamber that has a longitudinal body with a longitudinal passage supporting and passed through by the rotation axis, the rotation axis pivoting by being held axially in the measurement chamber, by a first axial end stop in the high position and by a second axial end stop in the low position, the centering bearing having, in the longitudinal passage, at least two cylindrical longitudinal support centering walls for the rotation axis.

Abstract: Methods and apparatuses for indicating the presence of a directional differential pressure between separated adjacent spaces are provided. A differential pressure set point indicator may be configured to correlate multiple potential angles of inclination of an elongated conduit to respective threshold differential pressures between two spaces which generate net flow of fluid sufficient to cause a lightweight ball to move from one region of the conduit to an opposing region. The elongated conduit may be adjustable in length so as to accommodate installation of the device into walls of varying thickness. The device may include a sound attenuator that reduces noise upon impact of the ball with either end of the conduit. The device may also include a sealing material that is flexible yet firm enough to provide both a seal with the exterior surface of the conduit and support for the conduit when oriented in a tilted configuration.

Abstract: A device, particularly a microfluidic system, is proposed, in which two cavities are arranged spatially close to one another and are sealed off from one another by a common cover. A fluidic connection can be produced between the cavities by movement of a pin-shaped body towards the cover. In this way it is possible to release a reagent in controlled manner without having to put it under pressure.

Abstract: A valve incorporates a device causing turbulents in the water stream just before passing over the turbine fins of the flow sensor. The device actually increases the Reynolds number or turbulence of the water stream increasing the contact of the water on the turbine. This causes the turbine to rotate more efficiently for the given flow volume passing over the flow measuring device. The improved efficiency results in better accuracy and performance over the entire flow range. In one embodiment the turbulent device forces the flow stream to rotate counter clockwise and hit the turbine fins causing higher force which makes the turbine turn more efficiently. The turbine is designed such that the major portion of the fin surface area is perpendicular to the turbulent flow stream. This opposed direction causes more force to be placed on the turbine fin by the water stream.

Abstract: Flow indicator with the purpose to indicate direction of the air flow between two rooms separated by a wall. The indicator comprises a tube (12) that is mounted in an opening of the wall (10). Inside the tube is a smooth-running body (16) mounted that easily moves towards the end of the tube by pressure difference arised air flow. Both ends of the tube are provided with end-stops (18) that are constructed to prevent the body (16) to leave the tube and are provided with one or more openings (20) that admits air to pass into the interior of the tube.
