This contribution presents a novel wear dependent virtual flow rate sensor for single stage single lobe progressing cavity pumps.We study the wear-induced material loss of the pump components and the impact of this material loss on the volumetric efficiency.The results are combined with an established backflow model to implement a backflow calculation procedure that is adaptive to wear.We use a laboratory test setup with a highly abrasive fluid and operate a pump from new to worn condition to validate our approach.The obtained measurement data show that the presented virtual sensor is capable of calculating the flow rate of a pump being subject to wear during its regular operation.
