Dinghua Radar Knowledge Lecture: How to Ensure the Accuracy of Measurement Data from Radar Level Gauges

Thread Content

With the widespread use of radar level gauges in the market, a variety of different models have emerged. As a measuring instrument, the core aspect and key factor is \"accuracy\"; the precision of an instrument has an impact on its practical application. Well, today I will explain to you: What factors can affect the measurement results of radar level gauges? https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/46dded28dbe04871b1c28ef5c252ce49~noop.image?_iz=58558&from=article.pc_detail&x-expires=1670382924&x-signature=1Q3iVt0UwQ4x2eY6H1lD3g%2BFY8w%3D https://p3-sign.toutiaoimg.com/tos-cn-i-qvj2lq49k0/be1d0fcd3fae4d86888b0f940ff6483d~noop.image?_iz=58558&from=article.pc_detail&x-expires=1670382924&x-signature=LhUhnhKPxQI9IWpuVzrCCBlsIDU%3D This issue also troubled our company’s technical staff in the past, but through their persistent efforts and extensive practical experience on site, they were able to resolve it. They identified the various situations that can occur, and we hope to share this information with everyone. 1. Overflow protection: For this situation, a corresponding distance can be set as the blind zone. 2. The size of the measurement range is related to the antenna, as antennas of different specifications have varying levels of precision. 3. The measurement range starts from the microwave beam up to the point at the bottom of the container; however, when the container is conical or concave, it becomes impossible to take measurements if the object being measured is below that reference point. This leads to inaccurate measurement data. 4. When the dielectric constant of the material of the object being measured is low, and the object is at a low liquid level, the zero point should be adjusted to ensure the accuracy of the measurement results. 5. If the object being tested tends to produce foam, it should be noted that depending on the concentration, foam can either absorb microwaves or reflect them; however, measurements can still be carried out under normal conditions. 6. Theoretically, the measurement results can be received once they are fed back to the top of the antenna; however, considering the possibility of erosion or adhesion, it is recommended that the measurement point be placed 100 mm away from the top of the antenna. In most cases, these 6 situations can affect the measurement results of radar level gauges, potentially impacting the accuracy of those measurements. Users are advised to handle such situations with care to avoid losses due to negligence. If you have any needs or questions, you can seek online consultation or contact Xi’an Dinghua Electronics.
