ALTAIR V4 DN25/32/40
VOLUMETRIC METER
Application
ALTAIR V4 represents the latest generation of volumetric meters developed within the framework of the MID and European standards to meet field requirements.
ALTAIR V4 is a particularly compact and robust meter, adapting to the most restrictive environments and compatible with varying water qualities.
Modular, ALTAIR V4 may be fitted at any time with an IZAR clip-on module converting it into a communicating meter, ready for mobile or fixed network (radio/wired) reading.
