Product Description

Radar Level Meter are 26G HF radar level meter, the maximum measuring distance of which reaches 70 meters.The antenna can be further optimized and the new-type microprocessor can process signal analysis of higher speed. So the meter can be used for: complicated measuring conditions of reaction still and solid material stock bin.

Characteristics

--Transmitting frequency as high as 26GHz
--Non-contacting radar, no abrasion and contamination
--Small sized antenna for easy installation
--Shorter wave length, better reflection achieved on inclined solid surface
--Smaller dead zone, better results ensured even in cannikin measurement
--Small beam angle and concentrated energy to avoid interferences
--Hardly influenced by corrosion and foam
--Hardly influenced by changes of steam vapor, temperature and pressure
--Hardly impacted by heavy dust
--High SNR to ensure performance even under fluctuation
--Choice for solid media and media with low dielectric constant

Operating Principle

Radar level meter antenna transmits narrow microwave pulse, which is top-down transmitted through antenna. The microwave is reflected after contacting the surface of measured medium and the signal is received by antenna system, then the part transmitted to electronic circuit is converted into material level signal automatically. (Because the microwave transmission is extremely rapid, so the round-trip time between the objective and the receiver is almost instantaneous.)
Note: Make sure that the highest material level does not enter into measurement dead zone when using the radar level meter. (As indicated Zone D in the figure).
