Yokogawa RotaMASS Nano Flowmeter

The world’s smallest dual bent tube Coriolis flowmeter series for highly accurate measurement at lowest flows.
The dual tube design compensates for fluctuations of density, temperature, pressure and environment conditions. This provides a consistent repeatable and accurate measurement especially for small size Coriolis flowmeters.

Typical Applications

  • Batching
  • Dosing
  • Blending
  • Chemical injection
  • Dosing systems
  • High pressure gases
  • Liquid and gas low flow measurement
  • Precision coatings
  • Metering pump control
  • Metrology
  • R&D laboratory
  • Vacuum thin film coating
