Turbine Water Flow Meter (Class B) DN 50mm to DN 200mm)
It's a high pressure water meter, for the measurement of high flows of cold potable water passing through the pipelines in sizes of 50mm to 200mm.
Features
*Magnetic drive, lower transmission resistance.
*Sealed dry dial register ensures clear reading.
*The measuring mechanism can be removable from the body for checking, maintaining and replacing, and the body needn't be dismantled from the pipeline.
*Inter-exchangeable parts.
*Low pressure loss. Long working life.
*Can be equipped with reed switch (register can't rotate).
Standard Compliance
Technical data conforms to ISO 4064 Class B, R50, R63 and R80 standard
Working Conditions
Water temperature: ≤50ºC for cold water meter
Water temperature: ≤90ºC for hot water meter
Water pressure: ≤1MPa or 1.6MPa or 4.0 MPa optional (10bar or 16bar r 40 bar optional)
Installation requirements
*The meter can be installed in horizontal, vertical or inclined position.
*A horizontal position with the register face upwards is recommended.
*Pipeline must be flushed before installation.
*The meter should be constantly full of water during operation.
Maximum Permissible Error
In the lower zone from Qmin(Q1) inclusive up to but excluding Qt (Q2) is ±5%.
In the upper zone from Qt(Q2) inclusive up to and including Qmax(Q4) is ±2%(cold water meter).
In the upper zone from Qt(Q2) inclusive up to and including Qmax (Q4) is ±3% (hot water meter).
