The Influence Of Waveguide Installation Method On Radar Level Gauge And Countermeasures

The reason why high frequency radar level gauge is installed in the waveguide is usually because there are too many interference signals in the tank and the real signal cannot be accurately detected. However, will it cause problems when installing Waveguide radar level gauge? Let's explore it below.

First, you need to understand the detailed working conditions of the site, including factors such as temperature, pressure, and media. Waveguide radar level gauge is usually used to measure liquids such as methanol, ethanol, crude grease and refined oil. In these working conditions, High frequency radar level gauge can be used and power-on debugging can be performed.

Through judgment and analysis, the on-site storage tank uses waveguide pipes for liquid level measurement, but there is a certain misalignment of the seams of the waveguide pipes, resulting in large interference signals. This example shows that problems can occur even with a Waveguide radar level gauge installed inside a waveguide. In order to fundamentally solve these problems, special attention needs to be paid when making the waveguide to ensure that there are no burrs and welds on the inner wall.

If these problems already exist and you don't want to remake the waveguide, what are the solutions? First, you can check the specific working conditions to see if Radar guided wave level gauge can be used to replace the traditional radar level gauge for liquid level measurement. Compared with traditional radar level gauges, the radar waves propagated through the detection component of guided wave radar level gauges are not easily scattered, the energy is relatively concentrated, and they are less affected by the outside world. Therefore, even if there are burrs or welds in the waveguide, you can consider using Radar guided wave level gauge.

Secondly, consider whether the waveguide can be removed. In some cases, waveguides are used to solve the problem of low liquid levels that cannot be measured. In this case, the problem can be solved by adjusting the range of the liquid level gauge to replace the waveguide.

In short, there is not just one way to solve the problem. When encountering problems during Waveguide radar level gauge measurement, we can think from multiple angles and find a solution that suits our working conditions. If you pursue efficiency, you can choose a simple solution; if you consider cost-effectiveness, you can look for a suitable solution from a cost perspective.
