<p>The method involves arranging the valves at the opposite ends of a test volume. An input pressure (p-e) lies against the valve (V1) upstream the test volume, while an output pressure lies downstream the test volume, behind the other valve (V2). The input pressure is greater than the output pressure. The former valve is controlled to open for a duration, while the latter valve is controlled to open for another duration. A pressure controller is retrieved and the method is interrupted with the identification of the leakage of the former valve.</p> |
