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 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 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:
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 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 balance or flow limiting valve (10) features a valve body/member (12) having a flow rate indicator/scale (44) containing setting having printed flow rates calibrated in units of measure in volume per time increment between a minimum flow rate position (MIN) and a maximum flow rate position (MAX); and a knob/handle (48) having a position indicator and being moveable to any continuous position on the flow rate indicator/ scale (44) between MIN and MAX in response to a user applied force, where the relationship between the flow rate indicator/scale (44) and the position indicator is based on calibrated flow characteristics of the balance or flow limiting valve. The user can set an exact desired flow rate in one operation by moving the knob/handle (48) to a desired position between MIN and MAX without consulting a printed flow curve or balance calculator to determine the desired exact flow rate.
