... fluid applies a force due to the Coriolis acceleration. The forces on the vanes result in a torque that can be measured on the axle of the driving motor. This torque is directly proportional to the mass flowrate of fluid passing through the measuring wheel. To verify the accuracy of the sensor, a medium...

..., over-torquing (uncontrolled down hole make-up) or, on the flipside, loosening of connections (reactive torque) is far too common and is intensified by the increase of laterals lengths. One cannot ignore our industry's extreme drive on operation efficiency and cost reduction. Unfortunately, ignoring...
