Precautions for radar level meter installation
Whether the radar level gauge can be measured correctly depends on the signal of the reflected wave. If at the selected installation location, the liquid level does not reflect the electromagnetic wave back to the radar antenna or there is interference in the range of the signal wave to reflect the interference wave to the radar level gauge, the radar level gauge will not accurately reflect the actual level.
Whether the radar level gauge can be measured correctly depends on the signal of the reflected wave. If at the selected installation location, the liquid level does not reflect the electromagnetic wave back to the radar antenna or there is interference in the range of the signal wave to reflect the interference wave to the radar level gauge, the radar level gauge will not accurately reflect the actual level. Therefore, the reasonable selection of the installation position is very important for the radar level meter, and the following points should be paid attention to when installing:
1. The axis of the radar level gauge antenna should be perpendicular to the reflective surface of the liquid level.
2. The stirring valve in the tank, the adhesion of the tank wall and the steps and other objects, if in the signal range of the radar level meter, will produce interference reflected waves, affecting the liquid level measurement. Choose the appropriate installation position during installation to avoid the interference of these factors.
3. The horn of the radar level meter should exceed the inner surface of the mounting hole by a certain distance (>10mm). The antenna of the rod type liquid level gauge should extend out of the mounting hole, and the length of the mounting hole should not exceed 100mm. For circular or elliptical containers, they should be installed at a distance of 1/2R from the center (R is the radius of the container)
