Description

The Newflow NANO Gen 300 (and older sibling NANO) is a safe area rail-mount flow computer for fiscal measurement, custody transfer, batch loading, and meter proving applications.

The NANO allows single-stream, multi-stream applications to be configured for simultaneous metering of both liquids and gases.
The device supports most measurement standards including AGA, ISO, GPA, and GERG for gas applications and API and ASTM for liquid applications.

  • Rugged & Reliable, Repeatable & Predicable
  • Designed for both control rooms and field mounting (-40 °C to +85 °C)
  • Low Power for a cool and reliable long service life
  • MID approvals from NMi & NMRO
  • Compact size simplifies refits and reduces cost of new installations
