ALTAIR V4 IS HOT WATER

VOLUMETRIC METER

Application

ALTAIR V4 IS HOT WATER is the latest generation of volumetric meter designed to measure the consumption of domestic hot water.
Compact and robust, ALTAIR V4 IS HOT WATER is easy to install and perfectly suited for varying water qualities.
Its integrated radio enables remote reading of the index and alarms of the meter in mobile mode (walk-by) or fixed network.
Developed within the framework of the MID, it complies with the European regulations and holds sanitary conformity certificates.
