3051SFA Annubar Flowmeter

Brand: Rosemount

The Rosemount 3051SFA Annubar Flow Meter is a no-equal solution with a patented, averaging pitot tube that delivers superior measurement accuracy over a wide flow range. 

This flow meter can measure multiple variables and is engineered with an integrated thermowell for temperature measurement. Its patented T-shaped sensor is capable of obtaining measurements via a single pipe penetration while maintaining a small profile in the pipe to reduce permanent pressure loss and increase energy savings.
Features
  • Designed with built-in flow calculations for direct reporting of fully-compensated mass flow
  • Patented T-shape sensor creates a fixed separation point for DP signal improvement over a wider flow rate
  • Advanced diagnostics provide diagnostic coverage to detect abnormal process conditions and electrical loop issues
  • Callendar-Van Dusen sensor matching improves temperature accuracy enabling best-in-class flow calculations
  • Ultra for Flow performance class enables optimized flow measurement with a Ā±0.04% of reading accuracy
  • T-shape Annubar design features very low permanent pressure loss
  • Integral thermowell of sensor adds process temperature measurement without additional pipe penetrations
  • All-welded, SuperModuleā„¢ design offers industry-leading accuracy in harsh environments and applications
  • Flowmeters come fully configured, leak-tested and ready to install right out of the box for fast installation
  • Sensor stagnation zone positioned to reduce noise, measurement inaccuracies and keeps particulates from clogging
  • SIL 2/3 certified to IEC 61508 (via 3rd party) and prior-use certificate of FMEDA data for safety installations
