SmartTrak® 100L, 100M & 100H



  • User Friendly Design
  • Ideal for OEM, Industry & Research Applications
  • Pressure up to 345 barg

SmartTrak 100L & 100M Flow Controllers

SmartTrak® 100 Series features performance, user-friendly features and flexibility.

The 100 Series gives users the world’s most linear sensor, smoother valve performance, more robust electronics and even more control over a wide
range of functions. The result is a series of mass flow meters and controllers that demonstrates premium flow instrumentation which is easy to use.

The 100 Series capillary MFM/MFC is designed so that the physics are correct. Excellent performance results from a patented, inherently linear Laminar Flow Element (LFE) design, advanced platinum sensor technology, and Vögtlin’s proprietary frictionless-hovering control valve.

The 100 Series is available with an innovative and user-friendly Pilot Module, a front-mounted or remote mounted control device that allows users to Dial-A-Gas, change flow rate, modify engineering units or re-configure the instrument. With the Pilot Module, the user can set zero, span, and full scale for each of the 10 different gases independently to accommodate unexpected application or system design changes.

The optional Compod modules add features like Modbus and Profibus dp communication, alarm points, analogue and i/o inputs, totalizers and pulse output.
For the ultimate in performance, flexibility and value, SmartTrak is the smart choice.

Features of the SmartTrak 100L, 100M & 100H Flow, include:

  • Measure and control gas mass flow rates up to 1000 ln/min
  • Pressure up to 345 barg
