Under the measurement conditions, continuous flow, memory and display of the total amount of cold (hot) water flowing through the enclosed full pipe.

Metering structure: single-stream or multi-stream structure is adopted.

Wet type movement: high sensitivity; special liquid encapsulation of the character wheel window can keep the reading clear for a long time.

Dry-type movement: magnetic transmission in the center of the movement, anti-magnetic interference, good stability, strong structure anti-freezing ability, clear reading

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

Temperature class: T30, T90

Accuracy Class: Class 2

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 high zone (Q2≤Q≤Q4) is ±3%
