Non contact radar level gauge

80GHZ radar level gaugeIt is a "top-down" measurement system based on the principle of frequency modulated continuous wave (FMCW). The antenna emits electromagnetic waves with continuously changing frequencies in the direction of the medium. After the electromagnetic waves reach the surface of the medium, they are reflected, and the reflected echoes are received by the antenna again.

FMCW principle: emission and transmission of continuous waves

R: The highest point of level measurement

H: Total distance for level measurement

D: Distance from the highest point to the surface of the medium

Therefore, there is a frequency difference between the transmitted and received signals at any point in time: Δ f=k * Δ t, where Δ t is the operating time of the electromagnetic wave and k is the slope of the frequency modulation. Δ t is related to distance D: D=Δ t * C/2, where C is the speed of light. Therefore, D can be calculated based on the measured frequency difference Δ f. Based on D, determine the actual level height inside the tank.
