Literature Select Your LanguageDeutschEspañolFrançaisItalianoRussianUK EnglishUS English Additional Tools:            Measurement Principle: Guided Wave Radar is based upon the principle of TDR (Time Domain Reflectometry). Pulses of electromagnetic energy are transmitted down a probe. The pulse is reflected when it reaches a liquid surface. Features: Low dielectric measurement capability Volumetric output Quick connect/disconnect probe coupling Operates in visible vapors and ignores most foams IS, XP, and Non-Incendive approvals Ignores coating buildup Applications: Liquids / Slurries / Solids Hydrocarbons to water-based media (dielectric 1.4 - 100) Most process or storage vessels up to 75 feet Bridles and by-pass chambers Power industry Sanitary 3A approved probe for food/beverage industry Options: FOUNDATIONfieldbus™ digital output Display/keypad Local remote mounting Interface measurement
