AI Technical Summary

⚠Technical Problem

Traditional positioning control technology in Coriolis mass flow sensors suffers from problems such as inconsistency in positioning, poor controllability, and low efficiency, which affect product assembly and performance.

⚗Method used

A self-aligning device for the spatial structure of a mass flow sensor is adopted, including a fixed support frame, a positioning block, a guide rail, a guide rail slider, an adjustment handle, and a connecting rod structure. By adjusting the handle, the guide rail slider is driven to move in the opposite direction on the guide rail, so as to achieve simultaneous positioning of multiple accessories.

🎯Benefits of technology

The positioning accuracy and consistency of accessories have been improved, batch production errors are controlled within 0.1-0.2mm, production efficiency has increased by more than three times, and product stability and reliability have been significantly improved.
