System for measuring change in fluid flow rate within a line |
摘要 |
A method and system for determining change in a fluid's flow rate 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, changes in the flow rate of the first fluid are determined.
