PCRL011 Radar level meter
Features
■Small antenna size, easy to install;
Non-contact radar, no wear, no pollution.
■Almost no corrosion, bubble effect; almost
not affected by water vapor in the
atmosphere, the temperature and
pressure changes.
■Serious dust environment on the high
level meter work has little effect.
■A shorter wavelength, the reflection of solid
surface inclination is better.
■Beam angle is small, the energy is
concentrated, can enhance the ability of
echo and to avoid interference.
■The measuring range is smaller, for a
measurement will yield good results.
■High signal-to-noise ratio, the level
fluctuation state can obtain better
performance.
■High frequency, measurement of solid
and low dielectric constant of the best
choice.

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).

Installation Requirements
Installation guide:
Be installed in the diameter of the 1/4 or 1/6.
Note: The minimum distance from the tank
wall should be 200mm.
Note: ①Datum
②The 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.

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.
