    Abstract: A controller for a municipal water system having a pump connected to a suction line, featuring a signal processor and a memory module configured to: receive suction line pressure sensor signaling sensed by a suction line pressure sensor arranged on the suction line and containing information about a suction line pressure of water flowing in the suction line; receive low suction pressure limit signaling programmed in the memory module and containing information about a low suction pressure limit of the water flowing in the suction line; and provide control signaling containing information to control the operation of the pump depending on a relationship between the suction line pressure and the low suction pressure limit, based upon the suction line pressure sensor signaling and the low suction pressure limit signaling received. The control signaling may contain information to reduce or stop the water flowing in suction line if the suction line pressure falls below the low suction pressure limit.

    Abstract: A pump controller has a signal processor that receives signaling about an instant water level AIL of a liquid in a container and generated by a water level transducer during an empty/fill application; and determines corresponding signaling to control a pump during the empty/fill application based upon the signaling received using a liquid level control algorithm that turns ON the pump and turns OFF the pump; controls the pump based upon a respective desired adaptive pressure set point SP* being defined from a respective adaptive liquid level control curve with respect to the instant water level AIL.

    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.
