Abstract
A flow system includes a pump, a motor connected to the pump that drives the pump and draws electrical energy and a sensor that measures the electrical energy drawn by the motor. The system also includes a control module for the flow system. The control module configured to perform a control module method that includes: receiving electrical data from the sensor; receiving operating characteristic data of the pump from one or more pump sensors; comparing the changes in the electrical data over time to the operating characteristic data; and determining a health of the pump on the comparison of changes in the electrical data over time to operating characteristic data.
