Altair V5

VOLUMETRIC WATER METER

Highly accurate, compact, modular and sustainable

Your benefit:

Only what is measured can be billed. A low starting flow rate and a high dynamic range help reduce the Non-Revenue Water level.

The ALTAIR success story continues with a new product design which has a decisive impact on the environment. The new generation ALTAIR V5 provides you with volumetric technology at its best: excellent metrological performance and long-term measuring reliability.

Suited for the most challenging environments. For efficient water management. For the reduction of non-revenue water. To conserve one of the world’s most valuable natural resources: water.

MEASURING DYNAMICS

  • Accurate measurements of low flow

  • Very low starting flow rate: < 0.2 l/h (DN15) / < 0.4 l/h (DN20), dripping water measurement

MEASURING RELIABILITY

  • Large filtration area

  • Optional dual-zone filter

  • Full resistance to blockages

  • Low pressure loss

  • Increased chlorine resistance.
