Radar Level Transmitter / Sensor for Corrosive Liquids

2-Wire Radar Level Transmitter - RD700

The extremely narrow microwave pulse emitted by the antenna on radar level transmitter can travel at the speed of light and part of its energy, which is reflected off the surface of the target medium, is received again by the same antenna. The time lapse between pulse emission and reception by the antenna is proportional to the distance between the surface of the target medium and the reference point on the antenna. However, due to the fact that the electromagnetic wave is transmitted at extremely high speed, which leads to a short time lapse (nanosecond level) and makes it difficult to be identified, radar level transmitter have adopted a special demodulation technology, enabling itself to detect the time lapse between pulse emission and reception correctly, and eventually generate accurate measurement results.


The electromagnetic wave radar level transmitter, operating at 26GHz as transmission frequency, offers the following unique features:

  • Non-contact measurement

  • Easy set-up and installation

  • High accuracy

  • Unaffected by dust, vapour or sonic profile in the vessel

  • Loop-Powered

Equipped with an advanced microprocessor and a unique electromagnetic wave signal processing technology, the radar level transmitter can be used under various process conditions.


Level measurement in liquids, especially highly erosive liquids.
