Abstract: A suction diffuser or arrangement is provided featuring a main suction diffuser body and a flow conditioning arrangement. The main suction diffuser body is configured with an inlet to receive an incoming fluid flow, an interior cavity to receive the incoming fluid from the inlet, and an outlet to receive the incoming fluid from the interior cavity and provide an outgoing fluid. The flow conditioning arrangement is configured in relation to the inlet and also comprises a flow conditioning portion having at least one inwardly contoured surface, configured to extend into the interior cavity, diffuse the incoming fluid passing from the inlet into the interior cavity, and provide a flow conditioning that produces a uniform flow of the outgoing fluid by directing the incoming fluid towards the outlet, based at least partly on a contoured design corresponding to the at least one inwardly contoured surface.

Abstract: The present invention allows for a combination valve in a hydronic HVAC system that functions as an isolation valve; a check valve; and as a device for measuring fluid parameters, such as flow rate, pressure, and/or temperature, and also allows for the isolation valve to be configured in the field to be mounted either in a straight 180 or an angled 90 orientation, as well as at an intermediate angle. The new combination of isolation valve, check valve, with embedded sensors for flow rate, pressure, and/or temperature measurement provides a more compact product envelope that achieves space savings, e.g., by eliminating the need for separate components in an HVAC system, such as separate isolation valves, check valves, flow meters, pressure gages, and/or thermometers.

Abstract: The present invention provides for a device or feature that incorporates a technique or means for flow measurement in a fluid flow system. By way of example, a contoured insert may be specifically calibrated to the pipe line size to ensure the desired accuracy of the flow measurement, irrespective of pipe length between the device and other fluid system components that would negatively influence other flow rate measurement devices. This in turn reduces the total number of components needed in a system.

Abstract: A valve includes a body having upstream and downstream ports, both ports configured relative to a common axis, and includes a ball arranged to rotate relative to the common axis between open and closed positions to allow for fluid flow/non-fluid flow. The ball has a calibrated member having a calibrated orifice that has a flow coefficient, pressure taps located upstream and downstream of the calibrated orifice and in communication with the upstream and downstream ports respectively to measure upstream and downstream pressures when in the open position, the upstream and downstream pressure taps are angled relative to the common axis, so conditions of fluid flow are determined based on a measured pressure differential between upstream and downstream pressure taps relative to the flow coefficient of the calibrated orifice when in the open position.

Abstract: A valve is provided having a valve housing/body configured to be arranged in, or form part of, a piping having a fluid flow, and configured with a pressure tap arranged at a location along the piping to allow pressure of the fluid flow of the piping to be measured, and also having a rotatable orifice plate configured to rotate in the valve body/housing on an axis of rotation positioned at a different location along the piping than the pressure tap for rotating between a first rotatable position for providing a normal fluid flow operation and a second rotatable position substantially perpendicular to the fluid flow for providing a direct flow measurement of the fluid flow determined based on signalling sensed by the pressure tap sensor containing information about a measured pressure at the pressure tap when the orifice plate is in the second rotatable position.

Abstract: A combination valve includes an isolation shutoff valve to prevent a fluid flow; a check valve to prevent backflow and gravity circulation of fluid flow; a pressure sensor to sense a pressure measurement of fluid flow and determine pressure sensor signaling containing information about a sensed pressure measurement; a temperature sensor to sense a temperature measurement of fluid flow and determine temperature sensor signaling containing information about a sensed temperature measurement; and a flow measurement sensor to sense a flow measurement of fluid flow and determine flow measurement signaling containing information about a sensed flow measurement.

Abstract: A contoured check valve disc features a pivot portion and a check valve portion. The check valve portion is attached to the pivot portion. The check valve portion has a near-sloped portion formed nearest to the pivot portion and a contoured surface curving away from the pivot point to a first point of inflection with a first curvature. The check valve also has a far-sloped portion formed farthest from the pivot portion and a contoured surface curving away from the point of inflection towards a farthest point away from the pivot portion with a second curvature that is less curved or bent than the first curvature. The near-sloped portion and the far-sloped portion combining to form a surface having a contoured pressure/force distribution on the first side to respond to the fluid flow and move the check valve portion away from the fluid opening.
