Recently, at the Dongjiakou Port Area of Qingdao Port, the inspectors of Qingdao Ocean Shipping Tally Company used mobile terminals to collect on-site ship weighing data by water gauge for the first time.

In the past, the inspectors recorded the data on the spot and input the calculation results manually, which was time-consuming and laborious. After more than 2 months of independent research and development, the company realized the functions of automatic accounting, automatic generation, automatic calibration and error prompting, which effectively increased the efficiency of water gauge weighing test by 20%, and realized paperless operation for the inspection.
