AI Technical Summary
The existing circuit Hall cannot be fixed on the Hessman plug, resulting in the need to replace the entire cover once it is damaged, which increases the cost.
Design a simple circuit flowmeter. The circuit hall is fixed in the circuit cover through a capillary tube. The capillary tube extends into the circuit hole on the cover. When the circuit hall is damaged, just replace the capillary tube with the circuit hall.
It realizes separate replacement of circuit devices, saving materials and reducing costs.
