The drawing of antenna lengths are respectively 138mm and 238mm.
For recessed environments, a recessed antenna should be selected.
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).
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).
Features
Ø Small antenna size, easy to install; Non-contact radar, no wear, no pollution.
Ø Almost no corrosion, bubble effect; almost not affected by water vapor in the atmosphere, the temperature and pressure changes.
Ø Serious dust environment on the high level meter work has little effect.
Ø A shorter wavelength, the reflection of solid surface inclination is better.
Ø Beam angle is small, the energy is concentrated, can enhance the ability of echo and to avoid interference.
Ø The measuring range is smaller, for a measurement will yield good results.
Ø High signal-to-noise ratio, the level fluctuation state can obtain better performance.
Ø High frequency, measurement of solid and low dielectric constant of the best choice.
The Installation Requirements
Be installed in the diameter of the 1/4 or 1/6. Note: the distance between the tank wall minimum distance should be tank high
Note: 1. datum
2.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.)
Ø Conical tank cannot be installed above the feed port.
Note: outdoor installation should adopt sunshade.
1. Correct
2. Error rainproof measures
Ø 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.

2. Error
Ø There are obstacles affecting measurement needed reflection plate.

The Electrical Connection
The power supply voltage:
(4~20)mA/HART (Two wire system)
The power supply and the output current signal
sharing a two core shield cable. The supply voltage range see technical data. For intrinsically safe type must be a safety barrier between the power supply and the instrument.
(4~20)mA/HART(Four wire system)
Separate power supply and the current signal,
respectively using a power cable. The supply voltage range see technical data.
RS485 / Modbus
Power supply and Modbus signal line separate drespectively using a shielded cable, the power supply voltage range see technical data.
