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.
