[0002] The guided wave radar level meter is a radar level meter based on the time domain reflectometry principle (TDR). The electromagnetic pulse of the radar level meter propagates at the speed of light along the steel cable or probe. When encountering the surface of the medium being measured, part of the radar level meter pulse is reflected to form an echo and returns to the pulse transmitter along the same path. The distance between the transmitter and the surface of the medium being measured is proportional to the propagation time of the pulse between them. The liquid level height is calculated. Since this level meter can realize non-contact detection operation and works stably, it is deeply favored by customers, especially in the field of high-temperature and high-pressure boiler detection.
