At the bottom‐orifices of downcomers three fluid flow states exist: liquid descending, vapor bubbling, and bridging. The three states are successfully measured with an ingenious layout of conductometric probes. The ratios of bubbling and bridging increase with increasing F‐factor and decrease with increasing liquid rate, and bridging really exists and is not negligible.
