Features

  • Quickly and directly measure gas specific gravity, molecular weight, relative and base density
  • Simultaneously calculate up to four gas purity curves to support each cycle of hydrogen-cooled generator operation
  • Purge without the need to reconfigure or recalibrate
  • See multivariable outputs including hydrogen purity, calorific value/BTU, Wobbe Index and mass or standard volume flow
  • Expand usage with a hazardous area-approved, head-mounted transmitter that supports local configuration and display
  • Quickly verify meter health and status using advanced internal diagnostics
  • Support multiple simultaneous protocols for connection to DCS, PLC and flow computers
  • Interact with our 3D model to learn more about our Compact Density Meters
