Precise Gas Flow Measurement and Control for High Flow Applications

One device provides measurement outputs for five process variables: mass flow, volumetric flow, temperature, pressure, and density. Achieve precise measurement of high flows up to 1500 slpm for Air and 3,000 slpm for Hydrogen. d•flux diagnostics make switching pure gases or gas mixes fast and easy in the field, with absolutely no loss in accuracy. Monitor and adjust it on the go with your mobile device through our Bluetooth App. d•flux’s field-proven capabilities make it an ideal choice for a wide range of applications, including biopharmaceutical and hydrogen production, carbon capture, food & beverage processing, and more.  

d•flux specifications deliver the revolutionary performance you demand.

  • High Accuracy - Up to +/-0.3% of user full scale and +/-0.5% of measured value
    • 5 sensor options to meet your budget 
  • Flow rates up to 1500 slpm (Air)
    • Other gases, according to coversion, Example: Up to 3120 for Hydrogen 
  • Multigas Capability – Pre-program 15 gases and/or gas mixes 
  • Monitor and control meter functions conveniently from your mobile device with free Sierra Flow Connector App
