Sierra Releases Next Generation High Performance Digital Mass Flow Meters and Controllers

Sierra Instruments is pleased to introduce Smart-Trak® 2, the next generation of its flagship Series 100 Digital Mass Flow Meters and Controllers.

Building upon the unprecedented performance, user-friendliness and flexibility end-users have come to expect with the original Smart-Trak, Smart Trak 2 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 doesn’t have to be difficult to use.

Smart-Trak® 2 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 Sierra’s proprietary frictionless-hovering control valve.

Smart-Trak® 2 is available with an innovative and user-friendly Pilot Module, a front-mounted or hand-held 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 10 different gases independently to accommodate unexpected application or system design changes.

Key New Functionality of The Smart-Trak® 2 Includes:

• True linear performance provides high accuracy and great flexibility in multiple gases
• With Dial-A-Gas® Technology, you select from up to ten pre-programmed gases or substitute your own
• Ability to adjust calibration in the field for each of these 10 gases independently
• Unique Pilot Module (mounted or hand-held) lets you view and change critical control functions in the field
• Proprietary frictionless-hovering direct-acting control valve technology
• MODBUS RTU networking capability with Sierra Compod™

With the addition of Sierra’s Compod™ Programmable Control Module, Smart-Trak® 2 transforms into a fully network-enabled MODBUS RTU device.

In addition, the new Smart-Trak® 2 offers a broad flow range, fast response time, excellent performance, unsurpassed instrument stability, and a host of functional enhancements. Smart-Trak® 2 is ideal for OEM, Industry, or Research applications. Constructed entirely from rugged 316 stainless- steel, the Smart-Trak® 2 can be used with almost any gas including toxics and mixtures.
