20140311254 | Rotatable Orifice Plate for Direct Flow Measurement - 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 signaling 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. | 10-23-2014 |
20140288716 | MIXED THEORETICAL AND DISCRETE SENSORLESS CONVERTER FOR PUMP DIFFERENTIAL PRESSURE AND FLOW MONITORING - The present invention provides apparatus featuring a signal processor or processing module that may be configured at least to: process signaling containing information about an equilibrium point of pump differential pressure and system pressure formulated in a hydronic domain by utilizing pump and system characteristic curve equations so as to yield system pressure and flow rate at any particular load and time in a pump hydronic system, including using a multi-dimensional sensorless conversion technique; and determine equivalent hydronic system characteristics associated with the pump differential pressure and flow rate to their corresponding motor power and speed reconstructed and remapped by using a discrete numerical approach, based at least partly on the signaling received. The signal processor or processing module may provide corresponding signaling containing information about the system pumping flow rate and pressure determined. | 09-25-2014 |
20140249682 | 3-D Sensorless Conversion Method and Apparatus for Pump Differential Pressure and Flow - The present invention provides apparatus featuring a signal processor or processing module that may be configured at least to: receive signaling containing information about calibrated motor speed and power data for a hydronic pumping system; and determine system pumping flow rate and pressure associated with an equivalent hydronic system characteristic variable, based at least partly on the signaling received. The signal processor or processing module may be configured to provide corresponding signaling containing information about the system pumping flow rate and pressure determined. The corresponding signaling may contain information used to control the hydronic pumping system. | 09-04-2014 |
20140140837 | FLOW CONDITIONING FEATURE FOR SUCTION DIFFUSER - 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. | 05-22-2014 |
20140137663 | VALVE BALL FOR DIRECT FLOW MEASUREMENT - 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. | 05-22-2014 |
