Radar level sensor wholesale from China? 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.
In the process of cement production, material level detection and material level alarm control play an important role from mining and crushing to storage and packing of finished cement. But because of the complex working conditions of cement plant, radar level meter has no small difficulty in measuring. Today, I would like to talk with you about specific difficulties and solutions. First cement plant material for measurement in the dust under the condition of particularly large, especially some pneumatic feed bin, involves the kinds of materials, material particle size is differ, dielectric constant is different also, such as broken limestone, raw meal, clinker, fly ash, coal, cement, the level of the bunker, it is very difficult to accurately measure Especially fly ash bin with low dielectric constant.
If the radar level meter is unreasonably selected, the interference echo cannot be handled well, and the reliability of the instrument will be reduced. Therefore, the following factors should be considered when selecting a radar level meter: Conductivity and dielectric constant of the measured medium. The measured medium is a conductive liquid or a liquid with a dielectric constant above 4. Generally, a common radar is selected. Liquids with small dielectric constants (dielectric constants below 2) and some conductive solids often use precision radars or guided wave radars due to the large amount of interference echoes.
The radar level gauge works by electromagnetic waves. Its working principle is to measure the specific liquid level by transmitting electromagnetic waves to the measured target. After the electromagnetic waves are emitted, they are reflected by the medium. For the radar level gauge, its key function is to ensure that it can transmit magnetrol guided wave radar signals smoothly. In our industrial production site, interference often occurs, so which interference sources will affect the measurement of the radar level gauge? let’s see.

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.
