IC card socket is waterproof, realize shower-waterproof, i.e. the product work normally when spray water on the outside of meter(≤2 hours); 3.The guider valve is immune from scale deposit and pressure, and it is more secure and stable. (Patent No. ZL00 2 05851) 4.The magnetic driven device separates the control circuit from water, which solve the problem of seal difficulty. 5. Anti vibration
