Key Considerations for Installing Radar Level Gauges

The radar level gauge features excellent temperature and pressure adaptability, and it is unaffected by the volatility of the medium during measurement. The radar level gauge has a low beam energy and can operate normally within the industrial frequency band without harming humans or the environment. The radar level gauge is a highly precise and accurate level gauge, and it must be properly installed and used to achieve good measurement results. The installation and use of the radar level gauge should pay attention to the following issues.

1. When installing radar level gauges, avoid the feed inlet, feed curtain, and vortices, as the liquid injection generates false echoes much larger in amplitude than the reflected echoes from the measured level. Additionally, the irregular liquid levels caused by vortices scatter microwave signals, leading to attenuation of effective signals. Therefore, it is advisable to steer clear of these areas.

2. For containers equipped with agitators, the installation location of the radar level gauge should not be near the agitator. This is because agitation creates irregular vortices that can cause attenuation of the radar signal. Additionally, the blades of the agitator can generate false echoes in the microwave signal, particularly when the relative dielectric constant of the measured object is low and the liquid level is low, making the impact of the agitator especially pronounced.

3. When radar level gauges are used to measure the level of corrosive and crystalline materials, manufacturers typically employ sensors with polytetrafluoroethylene coatings to prevent the medium from affecting the sensor.-Yi-Thermal-resistant film and split flange structure.

To avoid the impact of high temperature on radar antennas and to prevent crystallization from affecting the normal operation of instruments, it is required that there be a certain safety distance between the flange face and the *highest liquid level.

4. If the container equipped with a radar level gauge is concave or conical, pay attention to the lowest point position reached by the radar beam of the gauge during use. If the liquid level is below this point, measurement will not be possible. Therefore, adjust the lowest point position as much as possible to ensure the accuracy of the measurement results.
