Effects of changing vapor phase conditions on radiation-based continuous level measurement

摘要

Radiation-based continuous level gauges provide highly reliable measurements because no part of the instrument system is exposed to the process fluid, and they do not require penetration into the process vessel. To ensure accurate and repeatable measurement, users should carefully consider operating conditions inside the vessel. This study addresses the effects of a dynamic vapor space, where the atmosphere above the process fluid changes due to a reaction of process fluids and/or changes in temperature and pressure.
