Abstract

A pumping system for use in a subterranean wellbore below a surface includes a motor assembly, a pump driven by the motor assembly, and one or more sensors configured to measure an operating parameter within the pumping system and output a signal representative of the measured parameter. The pumping system further includes a wireless telemetry system that is configured to transmit data representative of the measured parameter from the pumping system to the surface. The one or more sensors may include acoustically active sensors that operate according to surface acoustic wave principles.
