ALTAIR V4 HOT WATER
ALTAIR V4 HOT WATER is the latest generation of volumetric meter designed to measure the consumption of domestic hot water.
Compact and robust, ALTAIR V4 HOT WATER is easy to install and perfectly suited for varying water qualities. It is also insensitive to magnetic fraud.
Developed within the framework of the MID, it complies with the European regulations and holds sanitary conformity certificates.
Modular, ALTAIR V4 HOT WATER can 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).
