Field of application

Promass Q 500 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. With its innovative remote transmitter Promass Q 500 maximizes installation flexibility and operational safety in demanding environments. Heartbeat Technology ensures compliance and process safety at all times.

  • Measuring principle operates independently of physical fluid properties such as viscosity or density

  • Highest measurement performance for custody transfer, density and under tough process conditions.

Device properties

  • Mass flow: measurement error ±0.05 % (PremiumCal)

  • Density: measurement error ±0.2 kg/m3

  • High turndown due to low pressure loss/zero point

  • Remote version with up to 4 I/Os

  • Backlit display with touch control and WLAN access

  • Standard cable between sensor and transmitter

Benefits

  • 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
