DETERMINING WHEN FLUID HAS STOPPED FLOWING WITHIN AN ELEMENT |
| 摘要 |
<p>A method and system for determining when a fluid has stopped flowing within a line. The pressure variation in a second fluid, separated from the first by a pumping membrane, is measured in response to energy applied in a time-varying manner to the second fluid. From the response of the second fluid to the applied energy, it is determined whether the first fluid has stopped flowing.</p> |
