Dinghua Radar Knowledge Lecture: The guided wave radar level meter produced by Xi'an Dinghua Electronics Co., Ltd. is suitable for liquid and solid powder measurement. It is dust-resistant and anti-corrosion. It is a good helper in the industry. However, when using the guided wave radar level meter, you must pay attention to the blind zone. So how should you pay attention? http://www.dhechina.com/ueditor/php/upload/image/20220928/1664331841442398.png Guided wave radar level timing is a radar material level designed based on TDR (time domain reflectometry). When the pulse emitted by the instrument is propagated to the surface of the medium to be measured by a steel cable or probe at the speed of light, part of the pulse is reflected, forming an echo, and returns to the transmitting device via the same path. The distance between the transmitting device and the surface of the measured medium is proportional to the measurement pulse propagation time. The height of the measured object is calculated through a formula. As mentioned in the previous article, there will be two blind zones during the measurement process of the radar level meter. The distance between the two blind zones is called the "effective measurement distance". When using the guided wave radar level meter, you need to pay attention to keeping the measured material between the two blind zones to ensure stable and accurate measurement data. http://www.dhechina.com/ueditor/php/upload/image/20220928/1664331816770383.png
