Apparatus and process for measuring the magnitude of leaks |
摘要 |
An accelerometer is attached to a pipe wall to measure the acoustic pressure waves generated in a fluid within the pipe as a result of a leak in a valve in the pipeline. Calibrating the accelerometer and tuning it to particular wave frequencies allows a determination of the magnitude of the leak through the valve.
