As a kind of non-contact measuring instrument, radar level meter is widely used in the level measurement of various liquid storage tanks.

However, in the actual installation process, some common misunderstandings may affect its measurement accuracy and stability. In this article, we will discuss the installation misunderstandings of radar level meters to help users better understand and avoid these problems.

Myth 1: Radar level meter is not affected by installation location

Some users believe that as long as the radar level meter is installed above the liquid level, accurate level measurement can be realized. In fact, the measurement effect of radar level meter is affected by the installation position. If the installation position is too high or too low, it may lead to signal attenuation, reflection or interference, thus affecting the measurement accuracy. Therefore, a suitable installation position should be chosen during installation, and it should usually be installed at a height of about 1-1.5 meters from the bottom of the tank.

Myth 2: Radar level meters are not affected by liquid properties

Different liquids have different properties such as dielectric constant, electrical conductivity and permittivity, all of which affect the propagation and reflection of radar waves. For example, conductive liquid may absorb the energy of the radar wave, resulting in measurement errors; and high dielectric constant of the liquid will make the radar wave scattering, affecting the strength and accuracy of the return signal. Therefore, when selecting a radar level meter, the characteristics of the liquid should be fully considered and the appropriate model and specifications should be selected.

Myth 3: Radar level meters are not affected by temperature and pressure

Temperature and pressure are important factors that affect the measurement of radar level meters. With the change of temperature and pressure, the propagation speed and dielectric constant of radar wave will also change, thus affecting the measurement accuracy. Therefore, when installing the customized radar level meter, the influence of temperature and pressure should be fully considered and corresponding compensation measures should be taken. For example, temperature and pressure sensors can be integrated in the radar level meter to compensate the measurement results in real time.

Myth 4: Ignore the details during installation

During the installation process, some details may be overlooked, thus affecting the normal operation of the radar level meter. For example, failure to align the reflective surface during installation, poor signal cable connection, antenna surface contamination, poor mounting bracket and other problems may lead to signal attenuation or distortion. Therefore, full attention should be paid to the details during installation to ensure the measurement accuracy and stability of the radar level meter.

In summary, in order to ensure the normal operation and measurement accuracy of the radar level meter, users should avoid the above misunderstandings in the installation process. In the choice of suitable installation location, consider the characteristics of the liquid, take compensation measures and pay attention to the details of the problem and other aspects need to be carefully operated. Only in this way can we give full play to the advantages of the radar level meter and provide users with accurate and reliable level measurement data.
