2 RD800 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 demodulation technology, enabling accurate detection of the time lapse between pulse emission and reception, thus generating accurate measurement results. Key Features The RD800 Series radar level transmitter offers the following unique features: Non-contact measurement Easy set-up and installation High accuracy Unaffected by dust or vapour Loop-Powered (HART Available) ATEX Approved Equipped with advanced microprocessor and unique Echo Discovery echo processing technology, the radar level transmitter can be used under various process conditions for liquid level measurement. Typical Applications Large storage tanks for oil and chemicals Deep sewage pumping wells Process vessels M200 Chemical Tank Water Tank Liquid Tank with Layer of Bubbles 2

5 Mounting Requirements The best mounting position for a conical vessel with flat top is the center of its top, as the effective measurement can reach the bottom of vessel. 1. Not Recommended: Do not mount the instrument in/above filling stream, which results in wrong measurement of target medium. 2. Recommended Antenna Extension The transducer end must at least protrude 10mm out of socket. Agitator If there are agitators in vessels, instrument must be mounted as far away from agitators as possible. Once installation completed, a false echo learning should be carried out while agitators in motion to eliminate negative influence caused by false echo of agitators. you are advised to opt for installation with standpipe if foam or wave is generated due to the action of agitators. NOTE : Please contact Flotech for other requirements. 5
