This maintenance-free solution for level measurement uses a pulse of microwave energy transmitted along a rod, wire or coaxial antennae, depending on the application. The energy reflection is bounced back, analysed and converted to a level indication by the electronic module in the signal processing unit. The instrument can be mounted directly into the process vessel, on the side of the process vessel (bypass chamber) or depending on design, into an existing mounted chamber, and can be combined with a magnetic level gauge for extra security of measurement.
