| Abstract: | In order to analyze the measuring and calibrating equipment of echo sounder and complete value transmission,two calibration devices were introduced in this paper. According to the specific conditions of environment, two methods using flume and simulator were provided. The basic principle and working process of echo sounder, the structure of two devices, test results, advantages and disadvantages were described in brief. |
