... to figure 2, which represents a typical flow pattern map relative to an upward vertical geometry [3]. Since the operating range of the flow meter is such that the gas superficial velocity is less than 3.5 and the liquid superficial velocity less than 1.5 , from figure 2, one can see that slug flow would...
