AI Technical Summary

Technical Problem

Traditional fixed mechanisms are easily displaced by fluid pulsation during flow meter calibration, resulting in reduced calibration accuracy. Furthermore, they are incompatible with flow meters of different pipe diameters, requiring the purchase of multiple fixed mechanisms and increasing costs.

Method used

The multi-structure clamping and fixing mechanism includes a motor-driven gear system and an adjustable clamping plate assembly. It clamps and fixes the flow meter in multiple directions, and combines springs and rubber gaskets to reduce displacement errors. The clamping plates can be replaced to accommodate flow meters of different specifications.

Benefits of technology

It improves the accuracy and production efficiency of flow meter calibration, reduces the cost of replacing the fixed mechanism, and achieves compatibility with flow meters of different specifications.
