Level Measurement Solutions for Fractionator Column Bottom and Trays
Continuous and point level measurement and control solutions for the refining industry
Accurate Level Measurement in Changing Process Conditions
It is essential to allow for highest possible product throughput through the Fractonator Column Bottom and Trays. Level measurement must be robust in order to resist build-up of sticky and viscous product, especially at the lower end. Overfill is unwanted as process media typically ends up in the flare system for hydrocarbons with the risk of a dangerous incident / explosion. Some users may prefer to measure the level directly in the tower while others may prefer the serviceability of cages with valves. If direct measurements are required, DP level is an appropriate solution. If bypass chamber is used, Guided Wave Radar together with a High-level alarm with point level measurement is the recommended solution.
