Distillation columns allow separation of fluid mixtures based on their boiling points. As vapors rise through the column, different components will condense at different temperatures and accumulate for withdrawal. Distillation columns will have a wide range of temperatures throughout. Fluids, especially at the lower end can be dirty and cause coating and plugging of equipment. If the bottom fluid is heavy, like tar, direct measurements is recommended and DP level is an appropriate solution to measure level. Otherwise, Guided Wave Radars technology installed in a chamber, cage or bridle is the recommended solution. Continuous radar level measurement can be combined with point level switch technology to add high and low level alarm.
