latest guided wave radar level factory for detecting

PRODUCT OVERVIEW

Kaidi KD-FMF11 FM radar level meter is a 120G FM radar type level measuring instrument with a measuring distance of up to 30 meters. The antenna is further optimized for processing and the new fast microprocessor allows for higher speed signal analysis and processing, making the instrument available for measurement of high temperature and high pressure and other environmental liquids.

THE PRODUCT PRINCIPLE

The general principle of frequency modulated continuous wave radar level meter is that the radar emits electromagnetic waves at the top of the tank, and the electromagnetic waves are received by the radar after hitting the medium and reflected. Because the speed of light C and FM slope K are known, so the frequency difference δ f is estimated, and the distance R of the material surface at the radar installation position can be obtained, and then the height of the material level is obtained by subtracting the spatial distance from the radar to the material surface (referred to as the empty height) from the known total height of the tank.
