AI Technical Summary

Technical Problem

Large-capacity weighing vessels cannot be sent to a third-party laboratory for traceability during calibration. In-situ calibration can easily damage the ground, and the weight configuration is cumbersome and insufficient, making calibration difficult.

Method used

The system employs a transfer tank and a weighing sensor system. Through liquid weighing calibration, a liquid of known weight is used as the calibration basis. The liquid is discharged into a large-capacity weighing tank for calibration, and then combined with a Mettler C10-class weighing sensor for precise measurement and adjustment.

Benefits of technology

It enables a precise and convenient calibration process, saves manpower and time costs, avoids ground damage and difficulty in weight configuration, and improves calibration efficiency.
