Abstract: Apparatus, such as a pump controller, features a signal processor configured at least to: receive signaling containing information about a linear set point control curve based at least partly on an adaptive set point control curve related to fluid being pumped by a pump in a pumping system, and determine a control set point based at least partly on the signaling received. The signal processor may be configured to provide a control signal containing information to control the pump based on the control set point determined.

Abstract: Apparatus, including a pump system, features a controller having a signal processor or processing module configured to: receive signaling containing information about a relationship between frequencies of pump vibration resonances detected around critical pump speeds and a 3-dimensional pump vibration power spectrum in the frequency domain with respect to pump speed and pump temperature change differences; and determine corresponding signaling containing information to adjust the pump speed to avoid the pump vibration resonances around the critical pump speeds, based upon the signaling received. The signal processor or processing module is also configured to provide the corresponding signaling as control signaling to adjust the pump speed.

Abstract: The present invention provides a numerical affinity pump sensorless conversion signal processing technique, e.g. based upon processing the pump differential pressure, flow rate and power at pump maximum speed published by pump manufacturers, as well as the pump affinity law in order to obtain instant pump differential pressures and flow rate directly and numerically. The sensorless converter technique may be applied to any form of pump characteristics distributions simple or complicated, since there is no need to reconstruct and to solve any pump and system characteristics equations. As a result, the computation accuracy is significantly improved.

Abstract: 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.
