Install in any conditions without influence on performance


ALTAIR V4 is the latest generation of volumetric water meters, which can be installed in any conditions without influence on performances. With its large measurement dynamic, it can measure leakages at very low flowrate.

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 can 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.
