8139 Radar Level Meter

The Type 8139 is a non-contact radar level measuring device for continuous level measurement. It is available with: – integrated antenna (G- or NPT connection), especially suitable for level measurement of aggressive liquids, with special advantages for small vessels – plastic horn antenna (with mounting bracket), especially suitable for measurements in open flumes or gauge measurement in water – flange connection (DIN 2501) with encapsulated antenna system – clamp connection (DIN 32676, ISO 2852) with encapsulated antenna system for hygienic requirements. The high focus of the radar signal and the high measurement dynamics allow excellent measurement results even in small, narrow and high containers, as the risk of signal interference by installations, constructions and vessel walls is much lowered. Signal damping, e.g. due to signal running length, foam build-up, low DK values of the liquids, has a much smaller effect.


  • Continuous level measurement up to 30 m, 4…20 mA, 2-wire
  • Available process connections: Plastic horn antenna, thread (G, NPT ¾ and 1½ ), flange (DN50, DN100), clamp (2″)
  • Excellent radar signal focusing and high measurement dynamics
  • Adjustable using the display/configuration module and keys, alternatively via PC-Tool with DTM
