‌1. Overview

It is mainly used in various tanks, pools, warehouses and other storage bodies, as well as rivers, ditches and other indoor and outdoor occasions, to measure the height, distance and level of powders, solids, liquids and so on. This product adopts FMCW (Continuous Frequency Modulation Wave) radar level sensing technology, which transmits microwaves to the surface of the medium and continuously modulates the frequency. At the same time, it receives FMCW continuously, and the frequency difference between transmission and reception is proportional to the distance to the material. The data can be read through the self-contained display, or through the output signal transmission to the upper computer or controller, to achieve timely and accurate determination and control of the silo situation.
