Abstract: Apparatus includes a signal processor that receives signaling containing information about real time pump operating parameters related to pumps forming part of a pumping system in a plant/facility, and a user input selecting a pump for displaying the real time pump operating parameters on a control monitor to allow a plant/facility operator to implement a centralized pump control of the pumps at a given centralized location; and that determines corresponding signaling containing information to display on the control monitor the real time pump operating parameters to allow the plant/facility operator to implement the centralized control of the pumps at the given centralized location, based upon the signaling received.

Abstract: An automatic self-driving pump system features a pump/motor/drive detector and an automatic self-driving and control design/setup module. In operation, the pump/motor/drive detector receives sensed signaling containing information about a pump/drive for operating in a hydronic pump system, e.g., stored in and sensed from a signature chip or barcode installed that can be scanned by a scanner, and provides corresponding database signaling containing information about parameters for providing automatic pump control design, setup and run to control the pump/drive for operating in the hydronic pump system, based upon the sensed signaling received. The automatic self-driving and control design/setup module receives the corresponding database signaling, and provides control signaling containing information for providing the automatic pump control design, setup and run to control the pump/drive for operating in the hydronic pump system, based upon the corresponding database signaling received.

Abstract: A pump controller features a signal processor configured to respond to signaling containing information about three corresponding discrete arrays with respect to a discrete motor speed for each system position at a motor speed derived from 3D discrete distribution surfaces of motor power, pump differential pressure and flow rate by respective numerical interpolations; and determine corresponding signaling containing information to control a pump, or pumps in a system of pumps, or a system of pumps based upon a corresponding pump differential pressure and flow rate at the motor speed for a corresponding power reading value determined using a numerical interpolation of the three corresponding discrete arrays, the signaling received. The signal processor is configured to provide the corresponding signaling as control signaling to control the pump, or the pumps in the system of pumps, or the system of pumps.

Abstract: Apparatus is provided featuring a signal processor or processing module configured to receive signaling containing information about a pump no flow idle (NFI) state when the pump is running at a pump idle speed; and determine corresponding signaling containing information about whether the pump should remain in a no flow shutdown (NFSD) state or the pump NFI state, based upon the signaling received. The signal processor or processing module is configured to provide the corresponding signaling containing information about whether the pump should remain in the NFSD state or the NFI state.

Abstract: 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.

Abstract: A signal processor receives signaling containing information about flow rates from sensorless converters in zone circulators in heating/cooling zones controlled by temperature sensors in a hydronic heating system in order to derive an adaptive pressure set point to meet the flow rates requested by the heating/cooling zones using an adaptive system and flow control curve equation, the signaling containing information about total flow rates requested by the zone circulators; determines desired pump speeds for the zone circulators to meet temperature requirements in heat zones; provides corresponding signaling containing information about the desired pump speeds; and/or determines the adaptive pump control curve equation based upon an adaptive system curve and as a moving maximum system flow rate depending on an adaptive pressure set point, a system flow rate requested by temperature loads, a minimum pressure at no flow, a control curve setting parameter, and an adaptive moving maximum flow and pressure.

Abstract: A discrete valve flow rate converter is provided to obtain a system flow through a valve in a dynamic hydronic pumping system, e.g., based on signaling containing information about the valve's differential pressure and the valve's hydronic characteristics calibration data. The discrete valve flow rate converter resolves the valve system flow rate directly and accurately with the valve's open position and the corresponding valve differential pressure signals associated therewith. The discrete valve flow rate converter may be applied to all kinds of valves as long as their open position and differential pressure associated with is available, e.g., including implementations for control valve applications, e.g., where the valve open position is controlled automatically and accurately, as well as implementations either for pumping system pressure controls with the flow rate known, such as adaptive hydronic system pressure controls, or as an alternative to sensorless pump monitoring and control.
