Applications

The Altair is a high performance oscillating piston water meter providing extreme low flow measurement. The Altair improves upon traditional positive displacement meters with a unique self-cleaning mechanism, which allows the meter to operate with dirty, gritty water. The composite meter is extremely light and does not require any straight pipe for installation.

The Altair is paired with the innov8 series of registers to provide smart metering capabilities with high resolution datalogging and a variety of AMR and AMI
options. This combination of design simplicity, superior grade materials, and high quality manufacturing standards allows for years of virtually new meter performance with no maintenance.

Operations

The Altair is designed with an oscillating piston with unique features to eliminate friction due to debris in the water.  As shown, water enters from inlet, drives the piston around the center roller and then exits the outlet.

To maintain accuracy, the meter must be installed horizontally (±10°) in the direction of water flow. 

Altair residential meters utilize innov8 registers.  These sealed electronic registers provide a high resolution interface to the meter and have multiple cellular, AMR, AMI and SCADA outputs.  All registers are attached with a robust tamper-resistant housing.

Design Features

  • High accuracy – exceeding high and low range of AWWA residential standards
  • Accurate measurement above 1/30th gpm
  • Unaffected by sand or small debris in line
  • Resistant to friction wear
  • No measurement of air in line
  • No straight pipe requirements upstream or downstream of meter
  • No strainer requirement
  • Lightweight and tough composite meter body

Materials

The Altair meters are designed and manufactured to meet  or exceed AWWA C710 standards design and performance specifications.  All Models are maintained with NSF-61G  lead-free certifications.
