• Product headline

  The flowmeter for cost-effective measurement and easy monitoring of utility gases.
  Suitable for air, nitrogen, carbon dioxide and argon in circular piping or rectangular ducts.

• Sensor features

  Optimal process monitoring – easy measurement even at low pressures and flow velocities. Cost‐effective measurement – easy installation, negligible pressure loss and maintenance‐free. Reliable flow trending – multivariable measurement.
  Insertion version for nominal diameter DN 80 to 1500 (3 to 60"). Installation and removal of sensor without process interruption. Easy installation.

• Transmitter features

  Fast and efficient commissioning – guided operating menus. High plant availability – self‐diagnostics and error monitoring. Automatic recovery of data for servicing.
