1. A computer program product for determining a change in a first fluid'"'"'s flow rate within a line, the computer program product comprising a computer usable medium having computer readable program code thereon, the computer readable program code comprising:
- program code for applying a time varying amount of energy to a second fluid separated from the first fluid by a membrane;
program code for measuring a pressure of the second fluid in response to the applied energy; and
program code for determining a change in the first fluid'"'"'s flow rate based at least on the pressure of the second fluid.

Abstract
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.
