MaxTrak 180 Industrial Mass Flow Controller
Max-TrakTM is an industrial mass flow controller from the company that has been a trusted name in industrial thermal mass flow controllers for decades — FLOWMETH and Sierra Instruments.
In applications where frequent wash-down / hose-down is required, such as food and beverage, chemical processing, pharmaceutical and biotech, FLOWMETH's and Sierra's Max- TrakTM outperforms the competition as it conforms to the rigorous requirements of NEMA 6 and IP67.
Excellent accuracy and reliability coupled with unsurpassed instrument stability result from a patented, inherently linear design, advanced platinum sensor technology and a valve that is strong and forgiving of variations in process conditions.
Max-TrakTM measures and controls gas mass flow from 10 to 1000 SLPM, with lower flows (to 2 SLPM) and higher flows available upon request. Based upon FLOWMETH's and Sierra’s successful Smart-Trak® line of digital instruments, Max-TrakTM also offers Dial-A-Gas® multi-gas capability, both analog and digital communication and a wide variety of field adjustable parameters.
