ALTAIR V3
ROTARY PISTON METER
ALTAIR water meter is characterized by its versatility. Its large measuring chamber means that it can be used for submetering or as a main meter.
ALTAIR is a modular meter and therefore can be fitted at any time with IZAR RADIO reading system, IZAR DOSING or the pulse emitter IZAR PULSE gateway to other systems.
