    Product details

    Product description

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


    Performance characteristics

    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

    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%
