AI Technical Summary
Directly reducing the cross-section of the pipe leads to irregular vortices and distortion of the velocity gradient, causing an imbalance in the impeller force and affecting the accuracy of the metering element.
The flow regulation chamber uses a mini cylinder to drive the cross-section adjustment block. Combined with the synergistic effect of the flow guide slope and the guide rod and guide cylinder, it achieves precise control of flow regulation, avoids local resistance, and amplifies the flow velocity.
It enables the metering element to accurately capture water flow velocity, improves the stability and adaptability of flow regulation, reduces system losses, and ensures long-term stable operation of the water meter under complex working conditions.
