HR80G 76-81 FMCW radar (also called millimeter wave radar) level meters, as it uses a millimeter wave band with a higher frequency than Ku band radar, long-distance imaging and multi-spectral imaging in remote target detection and strong smoke and dust environments, it  can detect smaller targets than microwave radar and achieve more precise positioning, it has higher resolution and stronger confidentiality.

 It has a maximum measuring range of 120m and measuring accuracy of ±1mm, supporting 4-wire and 2-wire.
