Azud DN80 Woltman Flanged Water Meter – MID-Approved, 16 bar, IP68
This Azud Woltman-type water meter is engineered for accurate bulk water measurement in large-diameter pipelines up to DN80. The helical-rotor Woltman design delivers reliable, low-pressure-drop measurement at high flow rates, making it the preferred choice for municipal supply connections, irrigation mains, industrial process water, and commercial building services. The brass body combines corrosion resistance with mechanical strength, while the blue epoxy-coated cast-iron outer casing provides additional protection against harsh outdoor environments.
The meter carries full MID (Measuring Instruments Directive) approval, confirming its accuracy class and legal-for-trade status across the European Union. Its IP68-rated, hermetically sealed register protects the dial and totaliser against permanent submersion, so the unit can be installed in underground pits or chambers that are subject to flooding without any risk of dial fogging or data loss. The flanged PN16 connections match standard DIN EN 1092-2 flange drilling patterns for straightforward drop-in replacement or new installation.

- Approval: MID (Measuring Instruments Directive 2014/32/EU)
- Typical installation: Horizontal (consult data sheet for inclined/vertical options)
Compatibility
The DN80 PN16 flanges comply with DIN EN 1092-2, making this meter directly compatible with standard ductile-iron, steel, and PVC flanged pipework of the same nominal diameter and pressure rating. The face-to-face length of 225 mm corresponds to the standard installation length for DN80 Woltman meters, allowing direct replacement of existing meters of this type without adjustment of the pipeline. Suitable for cold potable water (consult manufacturer for maximum temperature rating). Not rated for hot water, steam, or aggressive chemical media.

In details
- MID-approved for legal-for-trade and billing applications across the EU
- IP68 hermetically sealed register withstands permanent submersion in meter pits
- High Qmax of 126 m³/h handles peak demand on large irrigation or building-services mains
- Standard DN80 PN16 flange drilling allows direct drop-in replacement without pipework modification
- Brass body with epoxy-coated casing offers excellent corrosion resistance for buried or outdoor installations
- Unidirectional flow only — reverse flow is not measured and may damage the rotor
- Requires a minimum straight pipe run upstream and downstream for rated accuracy; cannot be installed immediately after elbows or valves
- Large size and weight require two-person installation and appropriate flange gaskets and bolts (not included)
