Radar level gauges are widely used in many industries. There are often some measurement factors that affect the accuracy of the radar level gauge. Poor working conditions on site will affect the measurement accuracy. The measurement accuracy can be improved from the aspects of selection, installation, and post-maintenance to meet the accuracy requirements. Below we analyze how to select, install, and maintain the radar level gauge from the perspective of affecting the measurement accuracy. 1. The dielectric constant of the measured medium The amount of reflected wave energy received by the radar level gauge depends on the reflection characteristics of the measured medium, and the reflectivity depends on the conductivity and dielectric constant of the measured medium. If the dielectric constant is low, the liquid with low conductivity will reflect weaker signal, resulting in serious signal attenuation. Therefore, the power of the electromagnetic wave signal source must be considered when the radar level gauge measures the liquid level. 2. There is steam or foam in the medium, which will affect the liquid level fluctuation or foam scattering of the measured medium, which will cause the signal to weaken. Therefore, it is necessary to increase the power of the signal source or add a waveguide. 3. When there are obstacles in the tank of the measured medium, false signals will be generated and affect the normal operation of the radar level gauge. For this reason, a powerful microprocessor should be used for complex signal processing. At the same time, try to avoid obstacles in the tank during installation. 4. Correctly install the radar level gauge The radar level gauge should be installed so that the electromagnetic waves emitted by the antenna are perpendicular to the liquid surface of the measured medium, and at the same time, the antenna should receive as many reflected waves from the liquid surface as possible. 5. Choose different shapes of antennas for different working conditions. In order to avoid the interference of the tank wall and the interfering objects in the tank, we recommend choosing a still-pipe to avoid disturbing the echo. The factors that affect the measurement accuracy of the radar level gauge are introduced above. We hope that the manufacturers of the radar level gauge and the users of the radar level gauge will analyze more on-site working conditions and on-site environment when considering the accuracy requirements, and propose to improve the measurement An efficient solution for precision.
