Level Measurement

Radar Level Transmitter

RD800 (Exia 30m Range)

RD800 radar level transmitter exia 30 meter range


Radar level transmitter RD800 adopted 26GHz as transmission frequency.
Equipped with advanced microprocessor and unique Echo Discovery echo processing technology, the radar level transmitter can be used under various process conditions.

  • Non-contact measurement
  • Easy set-up and installation
  • High accuracy
  • Unaffected by dust, vapour or sonic profile in the vessel
  • Loop-Powered (HART Available)
  • ATEX Approval (Ex ia)

RD800 supports level measurement in liquids, especially highly corrosive liquids.

  • Large storage tanks for oil and chemicals
  • Deep sewage pumping wells
  • Process vessels
