Abstract
An apparatus includes a sensor assembly disposable in a drill string proximate a drilling motor. The sensor assembly has a first pressure sensor in fluid communication with an upstream side of a rotor in the drilling motor, a second pressure transducer in fluid communication with a downstream side of the rotor and a rotational speed sensor coupled to the rotor. A processor is in signal communication with the first pressure transducer, the second pressure transducer and the rotational speed sensor.
