China class B removable element woltman type cold water meter
 

 

 

For the measurement of high flows of cold potable water passing through the pipelines in sizes of 40mm to 600mm.

 

*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
