Introduction:
The electromagnetic pulse of CS-102 series guided wave radar level gauge (hereinafter referred to as guided wave radar level gauge) propagates along the steel cable or probe at the speed of light. When it encounters the surface of the measured medium, some of the pulses of the guided wave radar level gauge are reflected to form echoes and return to the pulse emitting device along the same path. The distance between the emitting device of the guided wave radar level gauge and the surface of the measured medium is proportional to the propagation time of the pulses between them. The polarity and amplitude of the echoes depend on the dielectric constant ε r of the upper and lower media.

The guided wave radar level gauge is a radar level gauge based on the principle of time-domain reflection (TDR). The electromagnetic pulse of the radar level gauge propagates along the steel cable or probe at the speed of light. When it encounters the surface of the measured medium, some of the pulses of the radar level gauge are reflected to form echoes and return to the pulse emitting device along the same path. The distance between the emitting device and the surface of the measured medium is proportional to the propagation time of the pulse between them, and the liquid level height is calculated.

Comparison of different types:
The frequency modulated continuous wave radar level gauge is based on the principle of frequency modulated continuous wave (FMCW). Using linear frequency modulation high-frequency signals, the transmission frequency of the high-frequency signal of the radar level gauge increases linearly with a certain time interval (scanning frequency). As the transmission frequency varies with the time of signal propagation and is proportional to the distance from the reflected object, the height of the level is obtained by the difference between the current transmission frequency and the received reflection frequency.
