Proline Promass Q 300 Coriolis Flowmeter

Proline Promass Q 300 Coriolis Flowmeter

Promass Q 300 provides the highest measurement accuracy for mass flow, volume flow and density. Being the preferred choice for custody transfer applications, it has also been optimized for liquid applications where entrained gas is known to be present. The compact transmitter offers high flexibility in terms of operation and system integration: access from one side, remote display and improved connectivity options. Heartbeat Technology ensures compliance and process safety at all times.


  • Secured measuring quality – unmatched accuracy of mass flow, volume flow and density
  • Optimized performance for liquids with entrained gas – MFT (Multi-Frequency Technology)
  • Fewer process measuring points – multivariable measurement (flow, density, temperature)
  • Space-saving installation – no in/outlet run needs
  • Full access to process and diagnostic information – numerous, freely combinable I/Os and fieldbuses
  • Reduced complexity and variety – freely configurable I/O functionality
  • Integrated verification – Heartbeat Technology
