What factors should I pay attention to when selecting a radar level meter?

　　In non-contact level measurement, the application of radar technology has developed rapidly in recent years. Various types of radar level meters have their own characteristics and advantages. When selecting instruments for measuring media, various factors should be considered comprehensively, including the characteristics of the measured medium, the purpose of the medium measurement, and other factors such as environmental conditions and economic conditions. Try to make the best use of the strengths and avoid the weaknesses of many instruments and choose instruments that are suitable for the measurement medium and purpose.

　　1) Consider the characteristics of the measured medium. Since there are many types of radar level gauges, before measuring, the pressure, temperature, density and other characteristics of the measured medium should be considered first, and the appropriate antenna and meter head should be selected in a targeted manner. For high-temperature or highly corrosive media, a non-contact antenna radar level gauge should be used so that the level gauge does not come into direct contact with the liquid, which can not only ensure the accuracy of the measured data, but also protect the level gauge from damage.

　　2) Consider the purpose of medium measurement When selecting a radar level meter, you should also consider the purpose of medium measurement, so as to select level meters with different measurement accuracy. In order to save investment as much as possible, on the premise of meeting the measurement accuracy, try to choose a level meter with high cost performance. If the purpose of medium measurement is for internal accounting, the accuracy requirement does not need to be too high. If the purpose of medium measurement is for external transactions, you need to choose a high-precision level meter.

　　3) Installation of radar level meter The installation of radar level meter is also a very important part of liquid level measurement. In order to ensure the normal and stable operation of radar level meter, it is necessary to use a scientific and reasonable installation method to reduce the occurrence of various faults. During installation, the antenna and the measuring tank wall should be balanced. At the same time, the installation position distance should be greater than 300mm from the tank wall. Keep a sufficient distance, otherwise it is easy for the echo signal to be abnormal and cause a false echo signal. Consider other factors In addition, when selecting a radar level meter, it is also necessary to consider other factors such as environmental conditions, installation conditions, economic conditions, measurement range, frequency, etc.
