In order to enhance the extensiveness of the performance of radar level gauge, a series of problems existing in level measurement of liquid tanks are analyzed; based on the measuring principle and structural characteristics of radar liquid gauge, the measurement method combining radar level gauge and waveguide is proposed as a reference for the usage of the radar liquid gauge in chemical industries. The improved radar level gauge is simple in structure, and easy to install and maintain, which effectively avoids the interferences of level fluctuation in liquid tank and the measured media, the measurement precision can be improved by more than ten times, and the anti-interference capability is greatly improved, thus the stability and accuracy of the measurement results are ensured. The innovation of the improved radar level gauge lies on combining the advantages of the waveguide and the radar level gauge, and solving the limitations of level measurement using radar level gauge. The results of the study resolve the common problems in measuring the tank level, and provide some inspiration about using radar level gauges in petrochemical, coking and other industries.
