Liquid-sealed movement: high sensitivity; special liquid encapsulation of the character wheel window can keep the reading permanently clear.

Dry core: central magnetic drive, anti-magnetic interference, good stability, strong anti-freezing ability, and permanent clear reading.

Prepaid function, pay first, use later.

Support tiered water prices, one card with multiple meters.

Anti-magnetic interference function, low power consumption, long use time.

The enclosure protection grade is IP68.

Optional materials: ductile iron, engineering plastics, copper, stainless steel.

Environmental level: Class B electromagnetic environment: E1

Temperature class: T30, T90

Accuracy Class: Class II

Maximum Permissible Error

Maximum permissible error: low zone (Q1≤Q< Q2) maximum permissible error is ±5%

When the water temperature is less than or equal to 30C, the maximum permissible error in the high zone (Q2≤Q≤Q4) is ±2%; when the water temperature is> 30C, the maximum permissible error in the highzone (Q2≤Q≤Q4) is ±3%
