ALTAIR V4 CONCENTRIC

ALTAIR V4 CONCENTRIC

VOLUMETRIC METER

ALTAIR V4 CONCENTRIC is the latest generation of volumetric water meters specifically designed for installation on coaxial base in concentric manifold.
ALTAIR V4 CONCENTRIC 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.
Modular, ALTAIR V4 CONCENTRIC may be fitted at any time with an IZAR clip-on module converting it into a communicating meter, ready for mobile reading (walk-by, drive-by, passive drive-by) or fixed network reading (radio/wired).
