MEASUREMENT OF DYNAMIC GAS DISENGAGEMENT PROFILE BY USING AN ANALOG OUTPUT LEVEL GAUGE

The dynamic gas disengagement profile was measured in a 0.14 m diamete r and 3.66 m high plexiglas column by using an analog output gauge, wh ich was connected to a data acquisition system. This analog output gau ge is a high accuracy continuous measurement level gauge. It is made u p of a wave guide, a float, a motion or stress sensing device and a pr obe housing. The fluid level at any gas velocity is obtained by using the data acquisition system. The dynamic gas disengagement profile pro duced one slope in the bubble flow and two slopes in the churn turbule nt flow representing unimodal and bimodal distributions of bubbles.
