Radar level transmitter factory 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.

When the distance between the liquid level of the measured medium and the electromagnetic wave transmitter is less than 4m, the guided wave radar is selected. If the distance between the liquid level of the measured medium and the electromagnetic wave transmitter is greater than 4m and less than 35m, select the guided wave radar with the guided wave cable. When the distance between the liquid level of the measuring medium and the electromagnetic wave transmitter is greater than 35m, or when the liquid level of the measuring medium is high temperature, high viscosity or solid liquid level, the air-shooting radar should be selected.
So what can be done about these difficulties? Under the condition of strong dust, on the one hand, the radar with high transmitting energy can be selected, on the other hand, the measurement software with continuous measurement algorithm of wave-loss waiting can be selected. When the radar encounters strong dust, it will not misjudge the measurement result even if the radar loses wave for a short time. After entering the state of continuous measurement algorithm, if the reflection wave of real material surface can be recognized within the set waiting time, the correct measurement value of material surface can be obtained. In the past, only a few foreign radars have this function. At present, there are also domestic radars with this function, and the practical application effect is very good.
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.
Ground interference refers to one of the two output ends of the radar level gauge (or compensation line), and its AC voltage to the ground is called the ground interference voltage. This disturbance is also known as longitudinal, in-line mode or in-line state disturbance. Generally speaking, the interference voltage to ground can reach several volts or even more than 100 volts. The above is the interference of the radar level gauge we discussed. When we install or use the radar level gauge, we can also determine whether your use environment will cause these interferences to the level gauge according to the above situation. If these conditions exist, anti-interference measures must be taken to ensure that the level gauge can serve you better.
