The radar level gauge can be prepared for measurement based on the reflected wave signal. If the liquid level cannot reflect the electromagnetic wave back to the radar antenna or the interference wave reflects the interference wave to the radar level gauge in the selected installation position, the radar level gauge cannot accurately reflect the actual liquid level. We need to pay attention to the following points during installation:
1. Stirring valves in the tank, adhesions on the wall of the tank, and diameter and other objects, if they are within the signal range of the radar level gauge, interference reflected waves will be generated, which will affect the liquid level measurement; when installing, choose a suitable installation Location to avoid these situations;
2. For the measurement of the liquid level of a container with a large liquid level fluctuation, a liquid level meter with a bypass pipe can be selected to reduce the effect of the liquid level fluctuation;
3. The axis of the radar level gauge antenna should be perpendicular to the reflective surface of the liquid level;
4. The horn mouth of the horn-type radar level gauge should be spaced a certain distance (> 10mm) from the inner surface of the mounting hole. The antenna of the rod level gauge should protrude from the mounting hole, and the length of the mounting hole cannot exceed 100mm. For round or oval containers, they should be installed at a distance of 1 / 2R from the center (R is the radius of the container). They cannot be placed in round or oval containers.
The center of the oval container top, otherwise the radar waves will be collected at the center of the container top after multiple reflections on the container wall, forming a strong interference wave, which will affect the correct measurement.
