Product Description
Specification of Glass fiber Multi-jet Vane Wheel Water Meter
Application
Measuring the volume of cold potable water passing through the pipeline
Working conditions
Water temperature :≤50ºC
Water pressure: ≤1.6Mpa
Features
1.magnetic transmission ,
2.dry type register
3.advanced structure
4.internal strainer
Compliance with standard
Technical data conform to ISO 4064 class B
Standard for horizontal installation
Options
Non return valve for selecting
With threaded ends
Meter for hot water up to 90ºCis available
Installation requirements
The meter should be installed in horizontal position With the register face upwards
Pipeline must be flushed before installation
The meter should be constantly full of water during operation
Indicating error
At low zone is ±5% from minimum flow rate (Qmin) to transitional flow rate (qt) exclusive boundary
At high zone is ±2% from transitional flow rate (qt) to overload flow rate(Qs)
