As a non-contact measuring instrument, radar level gauge is widely used in the level measurement of various liquid storage tanks. However, some common mistakes may affect the measurement accuracy and stability during actual installation. This article will focus on the installation mistakes of radar level gauges to help users better understand and avoid these problems.
Myth 1: The radar level gauge is not affected by the installation position.
Some users believe that accurate level measurement can be achieved by mounting the radar level gauge above the liquid level. In fact, the measurement effect of radar level gauges is affected by the installation position. If the mounting position is too high or too low, it can cause signal attenuation, reflection, or interference, which can affect the measurement accuracy. Therefore, when installing, a suitable installation location should be selected, which should usually be installed about 1-1 from the bottom of the tank5 meters in height.
Myth 2: Radar level gauges are not affected by the characteristics of liquids.
Different liquids have different properties such as dielectric constant, conductivity, and dielectric constant, all of which affect the propagation and reflection of radar waves. For example, highly conductive liquids may absorb the energy of radar waves, leading to measurement errors; Liquids with a high dielectric constant scatter radar waves, affecting the strength and accuracy of the echo signal. Therefore, when choosing a radar level meter, the characteristics of the liquid should be fully considered, and the appropriate model and specification should be selected.
Myth 3: Radar level gauges are not affected by temperature and pressure.
Temperature and pressure are important factors that affect the measurement of radar level gauges. As the temperature and pressure change, the propagation speed and dielectric constant of the radar wave also change, which affects the measurement accuracy. Therefore, the influence of temperature and pressure should be fully considered in the installation of radar level timer, and corresponding compensation measures should be taken. For example, temperature and pressure sensors can be integrated into radar level gauges to compensate for the measurement results in real time.
Myth 4: Ignoring the details of installation.
During the installation process, some details may be overlooked, which will affect the normal operation of the radar level gauge. For example, problems such as misalignment of reflective surfaces during installation, poor connection of signal cables, contamination of antenna surfaces, and insecure mounting brackets can all lead to signal attenuation or distortion. Therefore, full attention should be paid to the details during the installation process to ensure the measurement accuracy and stability of the radar level gauge.
To sum up, in order to ensure the normal operation and measurement accuracy of the radar level gauge, users should avoid the above misunderstandings during the installation process. Caution is required when choosing the right installation location, taking into account the characteristics of the liquid, taking compensatory measures, and paying attention to detail. Only in this way can we give full play to the advantages of radar level gauges and provide users with accurate and reliable level measurement data.
