The BubbleMaster measures gas-liquid two-phase flows with optical fiber sensors. It not only measures time-averaged void fraction, but also detects individual bubble size and velocity using reflected light intensity technology that changes when a bubble penetrates the tip of the wedge-shaped optical fiber.
Three types of quartz sensor tips are available: S-TOP, T-TOP and F-TOP. The intrusive approach of the BubbleMaster enables to measure even at a higher void fraction of over 1 %, which cannot be realized by a non-intrusive optical method.
The BubbleMaster software acquires samples from individual bubbles, which signal amplitude can be monitored on the software display. Analysis results, histogram of bubble velocity and diameter, void faction, averages and standard deviation can be obtained with the T-TOP and F-TOP sensor.
