Features
High Accuracy at Low Flow
Designed for precise measurement even at very low flow rates, ideal for household usage.
Magnetic Transmission System
Ensures low transmission resistance and stable performance, reducing mechanical wear.
Clear and Reliable Reading
Dry dial or sealed register prevents fogging and contamination, ensuring long-term readability.
Durable and Corrosion-resistant Materials
Made from brass, stainless steel, or engineering plastics with anti-corrosion treatment.
Low Starting Flow Rate
Sensitive to small water usage, improving measurement accuracy for low consumption scenarios.
Easy Installation and Maintenance
Simple structure ensures convenient installation and long service life.
