Application:

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. Additionally, it is suitable for different types of water. ALTAIR is a modular meter and therefore can be fitted at any time with IZAR radio reading system, IZAR DOSING or the pulse transmitter IZAR PULSE, gateway to other systems.


Features:
  • DN 25 to DN 40
  • Starting flow at 5 l/h
  • Low head loss
  • Installation in all positions
  • Register with modularity "Ha + Ti"
  • MID up to R=800
  • High dynamic range
