1、 Measurement principle
Liaoning Xinruipeng Environmental Protectionradar level gaugeThe frequency modulated continuous wave (FMCW) radar measurement technology used is based on the principle of microwave reflection to achieve non-contact liquid level accurate detection, eliminating the disadvantages of traditional contact measurement instruments such as easy wear and corrosion, and being greatly affected by media. The instrument emits high-frequency microwave signals (frequency range 100MHZ-1.8GHZ) to the surface of the measured medium through an antenna. The microwave signals are reflected when they come into contact with the surface of the medium, and the antenna receives the reflected echoes and transmits them to the signal processing unit. After precise calculation, the liquid level height of the medium is converted and finally output in the form of digital or analog signals, achieving real-time monitoring, data uploading, and abnormal warning of the liquid level.
For the complex working conditions such as steam, foam, dust, strong acid and alkali corrosion, which are common in environmental protection scenarios, the product has been specially optimized and equipped with anti-interference echo processing algorithm, which can effectively suppress the interference of steam and foam on signals and ensure the stability and accuracy of measurement data. At the same time, based on the characteristics of the measured medium, three types of probes are provided: cable type, rod type, and coaxial tube type. The rod type and coaxial tube type have a range of up to 6 meters, and the cable type has a range of up to 30 meters, which can adapt to media with different dielectric constants.
