Abstract
A proposed implementation of this present subject matter utilizes a data collection and processing unit and sensors to monitor one or more conditions which can cause damage to a pump. These conditions include differential pressure across the pump, pump flow rate, and the pump rotational speed (RPM). Pump operating curves are analyzed to develop equations indicative of minimum and maximum allowable head for efficient operation within mechanical operation limits of the pump. The equations are used to set a processor for analyzing data inputs. The processor utilizes sensor inputs from the pump, including input and output pressure differential, flow, and pump speed. These values are compared to stored data or may be inserted into an equation to provide a calculated parameter indicative of operation in or out of pump operating limits. Responsive circuits inform users of alarm conditions.
