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: A valve includes a body having an upstream port to measure upstream pressure and a downstream port to measure downstream pressure, both ports configured re a common axis, and includes a ball arranged in the body to rotate re 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 to allow fluid flow and has a flow coefficient, an upstream pressure tap located upstream of the calibrated orifice and in fluidic communication with the upstream port to measure upstream pressure when in the open position, the upstream pressure tap angled re the common axis, and a downstream pressure tap located downstream of the calibrated orifice and in fluidic communication with the downstream port to measure downstream pressure when in the open position, the downstream pressure tap angled re the common axis, so conditions of fluid flow are determined based on a measured pressure differential between upstream and downstream pressure taps re the flow coefficient of the calibrated orifice when in the open position.

The adaptive moving average filter may be based at least partly on a system flow equation: SAMAt=AMAF(Qt/√{square root over (ΔPt)}), where the function AMAF is an adaptive moving average filter (AMAF), and the parameters Q and ΔP are a system flow rate and differential pressure respectively. The at least one memory and computer program code may be configured to, with the at least one processor, to cause the apparatus at least to obtain an optimal control pressure set point from the adaptive control curve with respect to an instant flow rate or a moving average flow rate as SPt=MA(Qt)/SAMAt, where the function MA is a moving average filter (MA), to obtain a desired pump speed through a PID control.

Abstract: A volute for a pump featuring a volute or casing having a pump inlet for receiving a fluid being pumped, a pump discharge for providing the fluid, and a volute or casing vane forming double volutes therein. The volute has an upper cutwater farthest from the pump discharge defining an upper cutwater throat area and an end of passage for the upper cutwater, and also has a lower cutwater closest to the pump discharge defining a lower cutwater throat and a corresponding end of passage for the lower cutwater. The upper cutwater throat area is dimensioned to be greater than and not equal to the lower cutwater throat area so the upper cutwater throat area and the lower cutwater throat area provide substantially equal flow velocity at both the upper cutwater and the lower cutwater in response to an angular sweep of the fluid being pumped. The end of passage for the upper cutwater is dimensioned with an upper cutwater passage area that is greater than and not equal to a corresponding lower cutwater passage area of the corresponding end of passage for the lower cutwater so that upper and lower cutwater passage areas at the pump discharge are balanced as a function of differing rates of flow of the fluid being pumped therein and so that the fluid being pumped from associated ends of the upper and lower cutwater passage areas meets at the pump discharge with a substantially equal velocity.
