PRODUCT DESCRIPTION

BENEFITS
  • Convenient installation, great flexibility, can be installed anywhere
  • Available as DN8, DN15, DN20, DN25 and DN32 G (female thread)
  • Accuracy of 1.5 % o.RDG, turn down ratio 100: 1
  •  Integrated data logger and pressure gauge option

The more accurate you can monitor gas flow, the more likely you will discover weak points in the process flow, thus ensuring continuity and profitability. Asymmetric velocity profiles, swirl, and other factors caused by bends in pipes can lead quickly to inaccurate readings. And it is often not possible to place flow meters at hard-to-reach places.


The solution is our new generation of compact, easy-to-install, reliable and
cost-effective flow and consumption meters: the S418.
