ABSTRACT:
A device installed in the reservoir drain line of a hydraulic pump or motor provides for the visual observation of an internally housed turbine whose rotations may be counted and, after comparing with elapsed time, used to determine, first, its revolutions per minutes and, then, by referring to a conversion chart, the fluid velocity of oil loss to the reservoir. If the loss to reservoir is greater than a known acceptable standard, the pump or motor may be repaired, overhauled or replaced.
