Description

The Diehl Metering ALTAIR V4 is a volumetric water meter designed for demanding field conditions and European MID requirements. It features a starting flow rate as low as 0.4 l/h, so even very small leaks are recorded. Whether installed in a horizontal, vertical, or inclined position, the ALTAIR V4 maintains its metrological performance, making it suitable for modern utility management and sub-metering applications.

Precision & Flexibility

Material Options Choose between the traditional brass body or the lightweight, corrosion-resistant composite version.
Any-Position Installation The volumetric principle allows for accurate measurement regardless of the installation angle or piping configuration.

Smart Utility Integration

• AMR/AMI Ready: Easily convert to a communicating meter by clipping on an IZAR radio or pulse module.
• Residential Billing: High dynamic range (R up to 800) provides high accuracy for billing.
