Precautions for using radar level meter in rainy season


With the rotation of the seasons, the arrival of the rainy season brings nourishment to the earth and challenges to many industrial fields.

In such a rainy season, for liquid storage and measurement of particularly important equipment - radar level meter, its correct use and maintenance is particularly critical. This article will explain in detail how to ensure the accuracy and reliability of radar level meters during the rainy season, as well as the key points to note.

First of all, it is fundamental to understand the working principle of radar level meter. It measures the level and distance of a liquid by transmitting microwave signals and receiving the signals reflected back. Since microwaves can penetrate many media, including plastic, glass and metal, radar level meters are widely used in the measurement of various liquids. However, during the rainy season, the increase in humidity may have an impact on the performance of the device.

The first point to note is to prevent moisture intrusion. Although modern radar level meters are usually designed to be waterproof, in rainy environments, it is still necessary to check whether the protection level of the equipment is high enough to prevent rain or moist air from intruding into the interior of the instrument, resulting in moisture damage to the electronic components. The second point is regular calibration. As the rainy season may be accompanied by temperature fluctuations, this will affect the density and refractive index of the liquid, which in turn will affect the measurement results. Therefore, it is recommended to perform at least one on-site calibration before the rainy season begins and after it ends to ensure the accuracy of the data. The third point is cleaning and maintenance. The moisture brought by the rainy season may cause more dust and impurities to adhere to the surface of the radar level meter, which will absorb microwaves and thus interfere with the accurate return of the signal. Therefore, regular cleaning of the antenna area to keep it clean and transparent is an important step to ensure measurement accuracy.

The fourth point is to pay attention to the installation location. When choosing the location for installing the radar level meter, low-lying areas prone to waterlogging should be avoided so that the equipment is not immersed in water for a long time, resulting in damage. At the same time, make sure that the installation location can effectively prevent rainwater from washing directly onto the equipment. The fifth point is lightning protection measures. Lightning is a common natural phenomenon during the rainy season, and the electronic equipment of the radar level meter is very sensitive to electrical surges. Therefore, it is important to ensure that the equipment has good grounding measures to minimize the risk of damage to the equipment from lightning strikes. The sixth point is to check cables and connections. Prolonged wet conditions can lead to deterioration or damage to cable insulation, as well as rust or corrosion of connectors. Regularly inspecting these components and replacing them when problems are detected are important measures to prevent failures from occurring. The final point is the preparation of backup solutions. In extreme weather conditions, any equipment can fail unexpectedly. Therefore, having a contingency plan and preparing standby level measurement equipment can ensure that production is not affected by a rapid switchover in the event of a problem with the main equipment.

In conclusion, when using radar level meters in the rainy season, special attention needs to be paid to such points as waterproof and moisture-proof, regular calibration, cleaning and maintenance, reasonable installation, lightning protection, checking cables and connections, and preparing back-up solutions. Through these meticulous precautions, you can ensure that the radar level meter can work stably and reliably even in the rainy season, providing a strong guarantee for the accurate measurement of liquid.
