LONG RANGE 2-WIRE RADAR LEVEL TRANSMITTER SERIES.
The extremely narrow microwave pulse emitted by the antenna of the 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, as the electromagnetic wave is transmitted at extremely high speed, which leads to a short time lapse (nanosecond level) making it difficult to be detected, radar level transmitters have adopted a special demodu- lation technology, enabling accurate detection of the time lapse between pulse emission and reception, thus generat- ing accurate measurement results.
The guided wave radar level transmitter, adopted 26GHz as transmission frequency, offers the following unique features:
• Non-contact measurement
• Easy set-up and installation
• High accuracy
• Unaffected by dust generation
Equipped with advanced microprocessor and unique Echo Discovery echo processing technology, the radar level transmitter can be used under various process conditions.
• Large storage tanks for oil and chemicals
• Deep sewage pumping wells
• Process vessels
• Mining water storage reservoirs
