Radar Level Transmitter's installation position

DATE: 2021-02-02
BROWSE TIMES: 361

The radar level transmitter should be installed to avoid contact between the sensor and the tank wall and should be kept at a certain distance from the tank wall. Because the radar level transmitter is measured by transmitting high-frequency microwave pulses along the detection component, the dielectric constant changes when these pulse waves encounter the measured medium, causing the emission. Therefore, if the installed radar level transmitter is too close to the tank wall, the dielectric constant of the tank wall may be obtained, which directly leads to the in accuracy of the measured parameters.


Correct installation method of radar level transmitter:

1. Installed one fourth or sixth of diameter.

Note:the minimum distance from the tank wall shall be one tenth of the tank height.

 Installation Position Selection of Radar Level Meter 1/2

2. For conical tank top plane, it can be installed on the middle of the tank top to ensure the measurement of the conical bottom.

3. When there is a pile, the antenna should be aligned perpendicular to the surface. If the material surface is not flat and the cone angle is too large, the universal flange must be used to adjust the angle of the horn so that the horn is aligned with the material surface.(Due to the inclination of the solid surface it will cause the echo decay or even the signal loss .)

4. The radar level meter should not be installed above the inlet of the conical tank. When installing outdoors, it should be protected from sun and rain.

5. The Radar level sensor can not be installed in the middle of the arch and round tank top. When the radar sensor is installed in the middle of the arched and rounded tank top, not only the indirect echo but also the multiple echoes will be received. The multiple echoes may be larger than the threshold of the true echo signal, because the top can be concentrated by multiple echoes.

    Radar level instruments measure the distance from the transmitter/sensor (located at some high point)to the surface of a process material located further below in much the same way as ultrasonic level sensor, by measuring the time-of -flight of a traveling wave and then determine the level of the process material. They are regarded as continuous level measurement devices because they continue to measure level even as the level of the liquid in the vessel changes.The fundamental difference between a radar level instrument and an ultrasonic level instruments is the type of wave used. Radar level instruments use radio waves instead of sound waves used in ultrasonic instruments. Radio waves are electromagnetic in nature (comprised of alternating electric and magnetic fields), with very high fr...

    The working principle and five precautions for using the radar level sensorThe radar level sensor is a measuring instrument based on the time travel principle. The radar wave runs at the speed of light, and the running time can be converted into a level signal by electronic components. The probe sends out high-frequency pulses and conducts them along the cable and rod probes. When the pulses meet the surface of the material, they are reflected back by the receiver in the meter, and the distance signal is converted into a level signal, Transmit-reflect-receive is the basic working principle of radar level sensor.The antenna of the radar sensor emits electromagnetic wave signals in the form of beams. The emitted waves are reflected on the surface of the material to be measured, and the ...
