Simultaneous determination of multiphase flow rates and concentrations |
| abstract |
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for determining the volumetric flow rates and volume concentrations (.mu.l) of the liquid and gas phase components in a multi-phase liquid-gas mixture in a pipe. The measurements are carried out by means of an ultrasonic system containing a set of local ultrasonic sensors (5, 6, 7) arranged inside the pipe. Each transmit and receive pair of pairs generates the sample volume of the measured medium. The volume concentration (s) of the composition component is determined by the timing of the acoustic pulse passage through the sample volume of the medium. The volumetric flow rates of the components of the mixture are calculated by measuring the velocity (w) of the phases and the volumetric concentrations (.fi.) In the two pipe sections having different cross-sectional dimensions that are spaced one after the other in the flow direction. |
