I. The Measurement Principle:

high-quality radar level gauge suppliers for industrial-1


Microwave antenna to receive the reflected pulse and transmitted to the electronic circuit, a microprocessor to signal processing, to identify the micro pulse generated on the material surface echo. Echo recognition is completed by the pulse system, the accuracy can reach millimeter level. From the material surface distance between D and T pulse is proportional to the time travel:

D=C×T/2

Where C is the speed of light

Because of the air tank is a known distance E, L:

L=E-D

 

By setting the empty tank height E (= zero), the full height of F (= full scale) and some application parameters, application parameters automatically makes the instrument to measure the environment. 4 - 20mA with a corresponding output.

l  Application:

 III. Installation Guide

  • Installation instructions:

    high-quality radar level gauge suppliers for industrial-9

       Ø  The recommended position (2), the outer wall of tank wall to install pipe shall meet the following from the tank wall best distance to tank diameter of 1/4 or 1/6, the minimum distance from the installation of tank wall as the measurement range of 1/10.

Ø  For example: liquid level of storage tank 10m, and the tank wall install the minimum distance of 1m.

Ø  Cannot be installed above the feeding port (4).

Ø  Cannot be installed in the central position (3), if installed in the central, yield multiple false echo, clutter echo will lead to real signal loss.

Ø  If you can't keep the instrument and the tank wall of the tank wall distance, the medium will adhesion caused by false echo, when debugging instrument should be false echo storage.


l  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 Universal joint flange of the antenna to the alignment surface.

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


  • Tank installation instructions:

    high-quality radar level gauge suppliers for industrial-12

Ø  In the signal beam, should avoid the following installation: 

Such as: (1) the limit switch, temperature sensor. 

Ø  Symmetric devices such as (2): vacuum ring, a heating coil, Baffle plate etc.

Ø  If the tank (1) (2) interference object, should be guided wave tube measurement.


Best installation options:

Ø  Antenna size: larger antenna, beam angle smaller, interfering echoes will be weaker.

Ø  Antenna adjustment: the antenna to adjust to the best measurement position.

Ø  Guided wave radar take over: The installation of the wave guide is used to avoid disturbing the echo.



  • Tank installation (801, 802)


A standard installation

Ø  The radar antenna cannot tilt to the tank wall.

Ø  In order to minimize temperature effect, at the junction of butt joint flange must use the spring washer.

Ø  The rod antenna launching point must reach out to install pipe.

Ø  The vertical placement of the rod antenna beam direction, don't let the tank wall.

Install short long antenna extension tube


Ø  When the horn length is less than the installation of tube length, tube using antenna

Ø  If the diameter of the horn tube diameter greater than the installation, you will need to increase meter elevation, extension tube. The antenna and the extension tube needs to be installed from inside the container. Select the extension tube makes the instrument at least elevation 100mm.

  • Measurement of Wave Guide Tube

    If there is an obstacle, such as a ladder, limit switches, heating equipment, such as a stent within the range of the microwave beam emitted radiation will lead to measurement errors. If affected, the need to add another wave guide measured.

                Note: 

               Isobaric pore diameter 5 ~ 10mm.

                      Wave guide diameter of at least 50mm, and the inner walls must be smooth.

                    Measuring only good mobility media, viscous media cannot be measured with a wave guide.


  • The bypass pipe installation

Ø  If the dielectric constant of the medium small (< 4), part of radar signal can penetrate the dielectric constant dielectric. Echo signal when the tank bottom reflection signals when compared to the dielectric reflection of strong, at this time, measurement error. In this case, can be at the bottom of the tank to install refraction board will signal refraction.


  • Typical installation errors

Ø  Conical tank cannot be installed above the feed port. 

Note: outdoor installation should adopt sunshade. 

high-quality radar level gauge suppliers for industrial-20


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.

V. Measurement Conditions


Matters needing attention:


l  The general measurement range is calculated starting from the bottom of the tank, under special circumstances, if the tank bottom is a concave or conical, when the level below this point cannot measure.  

l  Low dielectric constant in a low level, the bottom of the tank can be seen, this time in order to ensure the measuring precision, suggestions will be zero shift.   

l  Measurement of antenna theory to the position Of the tip is possible, but taking into account the effect of corrosion and adhesion, the measuring range of the tip distance of  100mm.

l  For overflow protection, can define a safe distance and dead area.

l  The minimum measurement range has relation with antenna.

l  Different concentration, foam can absorb microwave, also can be reflected, but under certain conditions can be measured. 

l  When no echo signal, the output current is 22mA.
