Smart-Trak Digital Mass Air Flow Sensor

Today's Most Advanced Mass Air Flow Sensors, Controllers and Flow Meters

Our award winning 100 Series premium digital family is made up of our flagship Smart-Trak® Model 100, our highly engineered ultra low flow solution, the Micro-Trak™  Model 101, and our Max-Trak® Model 180 industrial product. Ideal for OEM's and end users alike, our family of digital mass flow instruments are defining a new breed of Performance MFC & MFM.   The 100 Series products give you control, flexibility and independance with innovative features like Dial-A-Gas capability and the Pilot Module interface.   In addition, you can add the Compod™ programmable control module to all 100 Series models and get multi-drop RS-485/MODBUS RTU communications to greatly simplify basic flow control installations and permit networking of multiple instruments.

Featuring user-friendly features commonly found in today's consumer electronics and our most advanced sensor, valve and laminar flow element technology, we believe the 100 Series is one of our finest achievements.

Our 100 Series family of mass flow instruments is one of our finest technical achievements in over 35 years in the mass flow instrumentation business. Our 100 Series is designed so the physics are correct! Excellent accuracy and repeatability coupled with unsurpassed instrument stability result from a patented, inherently linear design, advanced platinum sensor technology, and a valve that is strong, flexible and forgiving. Our 100 Series family of instruments has raised the bar and set a higher standard in the Performance MFC marketplace. Here are five reasons why:

1.) Laminar Flow Element (LFE) Technology: Each instrument utilizes our patented, inherently linear, modular LFE design for linear performance beyond all other MFC's. This linearity enables our patented Dial-A-Gas® feature where every instrument can be used on up to 10 different gases at the push of a button, with comparable accuracy.

2.) Pilot Module Interface: Each instrument is available with our user-friendly Pilot Module, a front-mounted or hand-held control readout appliance that makes it simple to “Dial-A-Gas”, change flow rates, modify engineering units or even change the full scale value of your instrument. The design, focused on user-friendly interaction inspired by today's best consumer electronics, makes these instruments powerful tools that are fun to use.

3.) Adaptable & Flexible: Each instrument has been engineered with versatility in mind, so if actual process conditions vary from predictions, your instrument will remain within specifications. If flow conditions or system requirements change significantly, you can easily re-configure the instrument in the field to meet your evolving needs.

4.) Direct-Acting Valve Technology: Each mass flow controller has our robust and field-proven direct-acting valve technology to compensate for a wide variety of temperature and pressure variations in the gas stream. You can even adjust response characteristics, including PID values, for multiple applications or system pressure design changes.

5.) Ease-of-Use: Our goal with the 100 Series family of instruments was to make it the simplest and most trouble-free MFC on the market to install & operate. Recognized by both Flow Control and Gases & Technology Magazine as the leading MFC in the industry in 2006, the 100 Series was judged independently by gas flow experts and end-users representing science, academia and general industry. The 100 Series won specifically on ease-of-use, innovation, cost effectiveness, speed/throughput improvements, quality, maintainability, and environmental responsibility.

Digital Technology = High Level of Sensor Performance

Smart-Trak & Micro-Trak Performance MFC's and MFM's are the world's premier mass flow instrument for precision measurement and control of gas flows. Small in size, but outstanding in performance, Smart-Trak & Micro-Trak flow meters and controllers are loaded with user-friendly features that are programmable at the push of a button on the pilot module or from your personal computer.

Easy to Use Air and Gas Flow Measurement & Control

Our breakthrough Dial-A-Gas® technology allows a user to choose from a menu of 10 gases commonly used in many of today's top industries or to specify other gases to create a custom instrument for any application. These instruments are the most advanced in the industry today and one of our finest achievements.
