Radar level meter installation points
Whether the radar level gauge can measure correctly depends on the signal of the reflected wave. If the installation position is selected, the liquid level cannot reflect electromagnetic waves back to the radar antenna or there are interferors in the range of signal waves to reflect interference waves to the radar level meter, whether the radar level meter can correctly reflect the accurate liquid level.

Therefore, the normal installation and location of the selection of radar level meter is particularly important, today’s flow meter manufacturer Aister instrument for the installation of radar level meter need to pay attention to the following points.
1, the stirring valve in the tank, the adhesion of the tank wall and the ladder 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;
2, the horn of the radar level meter should exceed a certain distance from the inner surface of the mounting hole. 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;
3. The axis of the radar level meter antenna should be perpendicular to the reflective surface of the liquid level.
