ALTAIR V5 CONCENTRIC ROTARY PISTON METER
by DIEHL Metering
APPLICATION
The ALTAIR V5 CONCENTRIC is the latest generation of volumetric water meters specifically designed for installation on a coaxial base in a manifold. It adapts to the most demanding environments and varying water qualities while maintaining its excellent metrology. Developed within the MID framework, it complies with European standards and holds certificates of sanitary conformity.
The modular ALTAIR V5 CONCENTRIC can be fitted at any time with an IZAR clip-on module, converting it into a communicating meter. This enables mobile reading (walk-by, drive-by, passive drive-by) or fixed network reading (radio/wired).
FEATURES

- MID approval up to R=1000
- Starting flow rate at 0.4 l/h (for Q3 = 2.5 m³/h and Q3 = 4 m³/h)
- Composite or brass body
- Cold water
