NIVELCO TDR guided wave radar level gauge

The electromagnetic pulse of the 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 back 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 pulses between them. The polarity and amplitude of the echoes depend on the dielectric constant ε r of the upper and lower media. Generally speaking, the upper medium is usually a gas with a dielectric constant close to ε r1.0, while the dielectric constant of the lower measured medium is good.
