ALTImass Type U Coriolis Meter



  • Measures mass flow rate directly
  • Explosion-proof construction
  • Lightweight and compact

OVAL ALTImass Type U Coriolis Meter

The OVAL ALTImass Type U is a general purpose mass flow meter with versatile application for liquids and gases but offering specific options for high temperature (max 350°C) or low temperature explosion proof service (-200 to 50°C) and high pressure.

Features of the OVAL ALTImass Type U Coriolis meter include:

  • Measures mass flow rate directly
  • High accuracy, low pressure loss flow sensor for both liquid and gas
  • U-shaped flow tubes, the most effective design for sensing Coriolis forces
  • Measures density and temperature in addition to mass flow rate
  • Corrosion resistant, all stainless steel or Hastelloy construction
  • Lightweight and compact, yet with exceptionally high mechanical strength
  • Explosion-proof construction allows installation in hazardous locations
  • High pressure version available (max 430 bar)

Other Applications for the OVAL ALTImass Type U Coriolis meter include:

  • Monitoring concentration and solids content
  • Mass flow measurement of slurries
  • Cyogenic fluids such as LNG
  • Blending ingredients and additives
  • Flow metering natural-gas consumption
  • Pharmaceutical, cosmetic, and biochemical industries
  • Custody transfer
  • Catalyst addition processes
  • Suitable for flow applications where temperature and pressures fluctuate
