Max-Trak® Model 180 Mass Flow Controller

Industrial Mass Flow Meters and Controllers

Max-Trak® Model 180 Industrial Instruments with NEMA 6 / IP67 Rating

Max-Trak® is a family of industrial gas mass flow instruments from the company that has been a trusted name in industrial thermal mass flow meters for decades—Sierra Instruments. Max-Trak® will measure and control any clean, dry gas mass flow from 10 to 1000 SLPM, with lower flows and higher flows available upon request.

Max-Trak is available with Dial-A-Gas®,  capability through a remote pilot module or RS-232 computer interface to 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.

Based upon Sierra’s successful Smart-Trak® line of digital instruments, Max-Trak® adds rugged industrial packaging to popular premium features:

• Dial-A-Gas® multi-gas capability
• 316 stainless steel construction
• 4 types of analog and 2 types of digital communication
• a wide variety of field adjustable parameters
• compact sizes to measure and control flow rates from 10 to 1000 SLPM (higher upon request)

When added inside the industrial enclosure,  the internal Compod™ programmable control module gives RS-485/MODBUS RTU communications capability to the Model 180.  Compod greatly simplifies basic flow control installations to permit  networking of multiple instruments.

Product Overview Product Overview Product Overview Product Overview

Winner of numerous awards, Max-Trak® Model 180 instruments provide excellent accuracy and reliability, coupled with unsurpassed instrument stability, resulting from our patented inherently-linear body design, our advanced platinum sensor technology and a valve that is strong, flexible and forgiving.

Max-Trak® is well-suited for dirty industrial processes such as those found in metals and ceramics manufacturing, combustion control systems, chemical processing, pharmaceutical / biotech and the food and beverage industry where it outperforms the competition by meeting the rigorous water-resistant requirements of NEMA 6 and IP67. Model 180 gas flow meters and controllers can be used in a wide variety of process environments with optional 316 stainless steel flanges (ANSI or DIN) that compliment many other popular process fittings.

The extreme water-resistance, ease of installation, and rugged construction will give you confidence that Max-Trak® will continue to perform while the advanced features will provide you with information you can rely on for many years.

Electronic Mass Flowmeters & Mass Flow Controllers

Max-Trak® pressure insensitive mass flow controllers outperform all the competition. The Max-Trak® conforms to the more rigorous requirements of NEMA 6 and IP67. In addition, Max-Trak® controls gas mass flow rate from 10 to 1000 SLPM, with lower flows (to 2 SLPM full scale) available upon request. Since Max-Trak® is part of our leading edge 100 Series Digital family of mass flow controllers, it comes standard with Dial-A-Gas® multi-gas capability, both analog and digital communication, and a wide variety of field adjustable parameters.

The Max-Trak® provides excellent accuracy and reliability, coupled with unsurpassed instrument stability, resulting from a patented inherently linear design, advanced platinum sensor technology, and a valve that is strong, flexible and forgiving. The 0 to 200 SLPM version also features the only fully enclosed valve design to drastically minimize leak-in paths for MAXIMUM protection.
