1, the installation of radar liquid level timing, should avoid feeding mouth, feeding curtain and whirlpool, because the liquid will be injected in the amplitude of the measured liquid level than the reflection of the effective echo much greater false echo. At the same time, the irregular liquid level caused by the vortex will cause the scattering of the microwave signal;

2, for the container with agitator, the installation position of the radar level gauge will not be near the mixer, because it will produce an irregular vortex, which will cause the attenuation of radar signal. At the same time, the blade of the agitator can cause false echo to the microwave signal, especially when the relative dielectric constant of the measured object is small and the liquid level is low, the influence of the stirrer is more serious
