The Multi-Jet Water Meter is engineered for reliable measurement in residential and commercial water supply, constructed with a dry-type, magnetically driven design.
The Multi-Jet Water Meter is designed for accurate and stable water flow measurement in residential and commercial water supply systems. Featuring a magnetic drive mechanism and dry-dial register, it delivers reliable performance and long-term durability.
• Heavy-Duty Meter Body: High-strength cast iron construction provides exceptional durability and mechanical resistance.
• Cost-Effective Solution: An economical choice for large-scale residential water distribution projects.
• Epoxy Coating: Premium epoxy finish offers excellent protection against rust and corrosion.
• Multi-Jet Stability: Ensures consistent measurement accuracy under varying flow and pressure conditions.
• Dry Dial Register: The counting mechanism is completely isolated from water, providing clear reading visibility and preventing internal condensation.
• Magnetic Drive System: Ensures smooth and reliable transmission with minimal friction for extended service life.
• Magnetic Shielding Protection: Safeguards measurement accuracy from external magnetic field interference.
• Body Material: Cast Iron
• Accuracy Class: R80 / R100
• Available Sizes: DN15 - DN20 - DN25 - DN32 - DN40 - DN50
• Cold Water: 0°C - 30°C; 0°C - 50°C
• Hot Water: 0°C - 90°C
• Working Pressure: 1.0 MPa / 1.6 MPa
