Best radar level sensor wholesale? What are the characteristics of radar water level meter? All measuring components are designed in an integrated manner, and there is no mechanical wear during measurement. Because the measurement is a non-contact measurement, it is not affected by the physical properties such as the density and concentration of the water body, it is not easy to be washed away by floods, has a long service life and is easy to maintain. The advantages of the radar level transmitter are obvious. The editor warmly reminds that to choose the right one, it is still necessary to meet your own situation.

For the ultrasonic instrument that continuously measures the liquid level, when the temperature of the liquid to be measured changes greatly, the change of the propagation speed of the sound wave should be compensated. The connecting cable between the detector and the converter should take anti-electromagnetic interference measures. The structure of the ultrasonic level sensor should be determined according to the process requirements and on-site working conditions.
Secondly, in cement production, material level measurement encountered another difficulty is strong dust interference, especially pneumatic conveying powder silo, dust flying when feeding, low visibility, laser level meter and high energy ultrasonic level meter can not be measured, although radar level meter at this time can receive part of the surface echo. But the echo signal was also weakened. In addition, due to the uneven surface of the radar echo is refracted, will also lead to the existence of radar echo; In addition, there are some conditions from the bottom to the bin inflation, so that the material surface loose, material level measurement is more difficult.
Rod antenna: generally used in strong corrosive environments, with weak anti-interference ability and small range; Flare antenna: stronger anti-interference ability, suitable for more complex environments. The larger the bell mouth, the more concentrated the energy, and the larger the measuring range; Parabolic antenna: the focusing effect is stronger than that of the bell mouth, the anti-interference ability is the strongest, and the range is the largest.
For radar level gauges, there are many reasons for interference and many sources of interference. We analyze from four aspects: internal, external, AC and DC. Celestial and celestial interference, first of all, what is celestial interference? Celestial objects refer to the sun or other stars, therefore, celestial interference refers to the interference of their electromagnetic waves on the radar level gauge. We are very unfamiliar with Tiandian. The so-called Tiandian is usually understood as the interference of the signal of the magnetrol radar level gauge caused by the ionization of the atmosphere, lightning, or the electromagnetic waves generated by natural phenomena such as volcanoes and earthquakes.

The influence of dust accumulation on the transmitter head of the radar level meter, due to the large amount of dust in the working condition of the radar level meter, the dust is easy to adhere, and affected by the ambient temperature, the dust is wet and easy to agglomerate, and the dielectric constant will become larger and adhered The transmitter head and the wall of the bell mouth of the radar level meter affect the accuracy and stability of the radar measurement.
