Abstract:
A wirelessly powered system includes a wirelessly powered combination isolation valve and check valve for a hydronic system, having a positive shut-off isolation valve configured in the hydronic system to prevent fluid flow, including to allow for maintenance of the hydronic system, a check valve configured in the hydronic system to prevent backflow and gravity circulation which can harm the hydronic system, and a combination of one or more sensors configured to sense a corresponding combination of one or more pressure, temperature or flow measurements of the fluid flow in the hydronic system and provide sensor signaling containing information about the corresponding combination of the one or more pressure, temperature or flow measurements sensed of the fluid flow in the hydronic system; and an onboard wireless power receiver configured to receive wireless power signaling, and provide power to energize the combination of the one or more sensors.

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 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 pumping system featuring a pump, motor, a bearing assembly, integrated data acquisition system and combined programmable logic controller (PLC), data acquisition and modem. The pump couples to a pump shaft that responds to a pump shaft force to pump a liquid. The motor couples to the pump shaft, responds to VFD/VSD control signaling and provides the pump shaft force to drive the pump shaft. The bearing assembly includes a bearing with the pump shaft arranged therein and couples the pump and the motor. The variable frequency/speed drive (VFD/VSD) receives PLC control signaling and provides the VFD/VSD control signaling to drive the motor. The integrated data acquisition system responds to PLC data acquisition signaling, and provides integrated data acquisition system signaling containing information about an integrated set of pumping system parameters related to the pump, the bearing assembly, the motor and the VFD/VSD in the pump system. The combined programmable logic controller (PLC), data acquisition and modem provides the PLC data acquisition signaling and receive the integrated data acquisition signaling, provides PLC data acquisition modem signaling that exports performance data to the Internet to allow remote manual monitoring of the pump system, and provides the PLC control signaling to control the VFD/VSD and operate the pumping system as a controlled, closed loop system.
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.
