| This paper briefly introduces the measuring principle, classification and technical features of radar water gauges, while comparing the guided wave radar level gauge, non-contact radar water level meter and float level gauge, demonstrating some specific advantages of the guided wave radar level meter under some certain conditions. Based on the guided wave radar water level meter, a type of water level observation system is designed in this paper, with its composition, hardware design and software design briefly introduced. The measurement system has gone through calibration for the water level observation system, and the field installation test has been carried out. In the field experiment, the data obtained from the guided wave radar water level gauge are compared with those from the float type water level gauge, which shows the feasibility of adopting this design scheme for tidal level observation. |
