Abstract
Apparatus and methods related to flow rate testing are described. For example, some embodiments may contain a hydraulic power unit, a flow meter, a pressure gauge, an accelerometer, a reservoir containing testing fluid, two fitting connections, and hoses for interconnecting the components in a closed loop, for testing flow rate through a tube and pinpointing the obstruction location inside the tube.
Claims6
An apparatus for flow rate testing on a testing sample, comprising:
- a hydraulic power unit;

A method for flow rate testing on a testing sample, comprising:
- connecting a testing sample to a flow rate testing system, which comprises a hydraulic power unit to output inlet pressure, a flow meter to measure flow rate, a pressure gauge to measure pressure, an accelerometer to measure sound and vibration, and a reservoir tank containing testing fluid, all interconnected by hoses to form a closed loop;
- configuring the hydraulic power unit to output constant inlet pressure for a period of time, and record flow rate, pressure, and sound and vibration data;
- configuring the hydraulic power unit to output inlet pressure that oscillates between a maximum pressure and a minimum pressure periodically, and record flow rate, pressure, and sound and vibration data;
- analyzing the flow rate data to determine if an obstruction exists;
- and
- analyzing the sound and vibration data to determine the location of the obstruction.
