Guided wave radar level meter is suitable for a variety of process conditions of complex containers, tanks, silos, etc., and is not affected by changes in the physical properties of the measured medium, external measurement, two-wire technology, suitable for explosion-proof occasions, non-contact and continuous measurement of the pulse-type level meter large measuring distance of 35m.
Guided wave radar level meter measurement principle:
Guided wave radar is a measuring instrument based on the principle of time travel, radar waves run at the speed of light, the running time can be converted into level signals through electronic components. The probe sends out high-frequency pulse and spreads along the cable, when the pulse meets the material surface, it is reflected back and received by the receiver inside the instrument, and the distance signal is converted into the level signal.
