Description

Woltman Water Meter (Class B) DN 40mm to DN 600mm)

Removable Element Woltman Cold Water Meter (Class B) DN 40mm to DN 600mm)

Application

It's a woltman element water meter, for the measurement of high flows of cold potable water passing through the pipelines in sizes of 40mm to 600mm.

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). Removable Element Woltman Cold Water Meter (Class B) DN 40mm to DN 600mm)
