Overview Technical data Inquiry

Product Overview

This series of radar level meter adopted 26G high frequency radar sensor, the maximum measurement range can reach up to 80 meters. Antenna is optimized further processing, the new fast microprocessors have higher speed and efficiency can be done signal analysis, the instrumentation can be used for reactor, solid silo and very complex measurement environment.

Principle

Radar level transmitter antenna microwave pulse is narrow, the downward transmission antenna. Microwave exposure to the medium surface is reflected back again by the antenna system receives, sends the signal to the electronic circuit automatically converted into level signals (because the microwave propagation speed, electromagnetic wave to reach the target and the reflected back to the receiver this time is almost instantaneous)

 

A :Range Set

B :Low Adjustment

C :High Adjustment

D :Blind Area

Datum measurement: Screw thread bottom or the sealing surface of the flange

Note: Make sure the radar level meter the highest level cannot enter the measuring blind area (Figure D shown below).

Application

 

  • Solid particles, Powder

?Installation Requirements

Be installed in the diameter of the 1/4 or 1/6

Note: The minimum distance from the tank

wall should be 200mm

Note: datum .The container center or axis of symmetry

 

 

The top conical tank level, can be installed at

the top of the tank is intermediate, can guarantee

the measurement to the conical bottom

A feed antenna to the vertical alignment surface

If the surface is rough, stack angle must be used

to adjust the angle of cardan flange of the antenna

to the alignment surface

(Due to the solid surface tilt will cause the echo
attenuation, even Loss of signal.)

Typical installation errors

Conical tank cannot be installed above the feed port.

Note: outdoor installation should adopt sunshade

  1. Correct
  2. Error rainproof measures

 

 

The instrument cannot be installed in the arched or domed roof intermediate. In addition to produce indirect echo is also affected by the echoes. Multiple echo can be larger than the real value of signal echo, because through the top can concentrate multiple echo. So cannot be installed in a central location.

  1. Correct
  2. Error

There are obstacles affecting measurement needed reflection plate

  1. Correct
  2. Error
