Abstract
A hydraulic power unit, a flow meter, and a pressure gauge couple to a first end of a tube under testing. The hydraulic power unit provides an inlet pressure to move a testing fluid through the tube. The flow meter measures a flow rate of the testing fluid and the pressure gauge measures the inlet pressure. An accelerometer measures sound and vibration of the tube. A reservoir couple to an outlet of the tub and an inlet of the hydraulic power unit. The reservoir supplies the testing fluid to the hydraulic power unit and collects the testing fluid from the tube. Hoses interconnect the components in a closed loop that reuses the testing fluid. By analyzing the flow rate, it is determined if an obstruction exist in the tube. By analyzing the inlet pressure and the sound and vibration of the tube, a location of the obstruction is determined.
