Product Description

High frequency liquid wave radar level meter 

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
1. Transmitting frequency as high as 26GHz
2.  Non-contacting radar, no abrasion and contamination
3. Small-sized antenna for easy installation
4.  Shorter wave length, better reflection achieved on inclined solid surface
5. Smaller dead zone, better results ensured even in cannikin measurement
6. Small beam angle and concentrated energy to avoid interferences.
7. Hardly influenced by corrosion and foam.
8. Hardly influenced by changes of steam vapor, temperature and pressure.
9. Hardly impacted by heavy dust.
10. High SNR to ensure performance even under fluctuation.
11. 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.
