Application:

ALTAIR CONCENTRIC is a volumetric water meter. Its metrological performance matches the ALTAIR in-line meters : high dynamic range, very low start flowrates, low head loss and strong resistance to overflowrates. ALTAIR CONCENTRIC is compact. Its low profile means that it can be installed on a coaxial base in a concentric manifold. ALTAIR CONCENTRIC meter is modular and can be fitted at any time with an IZAR radio reading system, an IZAR DOSING device or an IZAR PULSE transmitter, gateway to other systems


Features:
  • Available in Q3=2.5 & Q3=4
  • Approved MID up to R=500
  • Glass metal register in standard
  • Composite and brass body version
  • High dynamique range
  • Start flowrate at 2 l/h
