FlatTrak® 780s

Sierra-flattrak 780s with Datasheet

The FlatTrak™ 780S flow body eliminates velocity profile distortions, swirl and temperature
stratifications in the gas stream and reduces the amount of upstream piping required for accurate flow measurement.


  • Direct mass flow monitoring eliminates need for seperate temperature and pressure inputs
  • Built-in flow conditioner which eliminates velocity-profile distortions caused by upstream disturbances
  • Accuracy +/- 1% of reading plus 0.5% of full scale
  • Patented Dry-Sense™ technology eliminates sensor drift
  • State-of-the-art calibration facility
  • insures a highly accurate calibration that matches the application
  • Field validation of meter electronics and sensor resistance verifies flow meter performance
  • One-second response to changes in flow rate
  • FM, CSA, PED and ATEX certified for hazardous areas
  • CE approved
  • Multipoint options available
  • Integrated purge option available
  • Optional HART, Modbus and Profibus
  • DP available, Foundation Fieldbus
