Select the Right Liquid Level Sensor

摘要

LEVEL MEASUREMENT, which is the detection of the phase split between vapor/liquid, liquid/liquid, vapor/solid and even liquid/solid, is a key parameter in the operation and control of modern industrial processes. A reliable outcome depends on the phase conditions being relatively consistent under all process conditions. Unfortunately, the importance of level control isn't always appreciated (see "Don't Underestimate Overfilling's Risks," www.ChemicalProcessing.eom/ articles/2010/143.html). Failure to measure level reliably has resulted in some of the most serious industrial accidents, including those at the Buncefield, U.K., fuel storage depot and BP's Texas City refinery.
