ALTAIR V4 DN15/20

ALTAIR V4 DN15/20

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 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.

    This technology does not require straight length.

  • Options

    - Non-return valve | - Pair of connectors | - Glass/metal register
    - Patented dual-zone filter. More efficient, it replaces glove finger filters. This new filter considerably slows down the aging of the meter.
