SmartTrak® 100 Series High Pressure

Enquiry Item
SmarTrak 100HP combines the high performance of the SmartTrak® with a wider, more robust flow body, all-welded sensor seals, an innovative new valve design called ValFlex™, and a state-of-the-art high pressure calibration facility. The result is an instrument with increased application flexibility and accuracy in high pressure gas flow control applications.



  • Ideal for pilot plants, hydrogenation reactors, and autoclave processes
  • Measure and control gas mass flow rates over an inlet pressure range of 500 to 5000 psig (34.5 to 345 barg)
  • Flow ranges from 100 sccm to 20 slpm
  • High accuracy +/- 1.0% of full scale; repeatability +/- 0.2% of full scale
  • Wide differential pressure range from 0.345 bard (5 psid) to 345 bard (5000 psid)
  • Innovative new ValFlex™ control valve design for precision control over a wide range of pressures and flow rates
  • Leak-by of as little as 4 sccm at 5000 psid (345 bard), depending on orifice
  • Inert, carbon-reinforced polyamide valve seat increases valve durability and precision
  • Special high pressure rated seals minimize gas permeability
  • Add Sierra’s Compod™ to run small-scale pilot plants or control high pressure reactors and autoclave processes without the expense of DCS or PLC systems.
  • Proprietary high pressure calibration facility, directly traceable to NIST
  • 24 VDC input power reduces installation cost and complexity
  • Unique Pilot Module (mounted or hand-held) lets you view and change critical control functions
  • Choose from multiple analog or digital signals Supports Modbus, Profibus DP, Foundation Fieldbus
  • CE approved
