Measuring Container
Use this container for doing hydraulic motor efficiency
testing (motors with case drain lines only). Measure effi-
ciency of a hydraulic motor by restricting the outlet flow
from the motor and measuring leakage from the case
drain line while the motor is pressurized by the hydraulic
system.
The table in Figure 15 provides gallons per minute
(GPM) conversion for measured milliliter or ounce motor
case drain leakage.
