Working principle Working principle Concentration, void fraction Velocities Bubbly flow Phase indicator function Chords Optoelectronic module Optical fiber link (customer-defined length) The operation of B-POP relies on measuring the reflection of a laser beam at the probe tip. The sensor is sensitive to the refractive index of the surrounding phase and detects the phase changes at a given location. Velocity measurements are based on the propagation of the liquid-gas interface along the sensing tip (rising time of the signal). B-POP works by contact and does not require any light...
