DETERMINING WHEN FLUID HAS STOPPED FLOWING WITHIN AN ELEMENT |
| 摘要 |
<p>The time derivated pressure variation in a second fluid, separated from a first (13) by a pumping membrane (12), is measured (15) in response to energy (16, 17) applied in a time-varying manner to the second fluid. After low pass filtering, below a threshold, a stop is indicated.</p> |
