Product Overview

The Helix H4000 is a robust Woltmann-type turbine water meter designed for measuring bulk flows of cold potable water in commercial, industrial and utility applications. It features high performance over a wide flow range, forward and reverse flow capability, inductive pulse output for AMR integration and long service life in demanding environments.

Key Features

• Wide flow range coverage (from ~0.35 m³/h up to 2,000 m³/h)
• Suitable for forward and reverse flow metering
• Maximum working water temperature up to 50 °C
• Maximum working pressure up to 16 bar
• Inductive pulse output for remote reading and AMR systems
• Exceeds ISO 4064 Class B (and similar) for accuracy in forward flow; many sizes also exceed in reverse flow
• Durable construction: epoxy powder-coated cast body and cover, hard-surface rotor bearings (tungsten carbide & synthetic sapphire)
• Multi-position installation (horizontal, vertical, inclined) with minimal effect on accuracy
• Suitable for commercial buildings, utilities, large-scale metering & distribution networks
