After reading Kam's last post about how Sierra's OEM and Custom Solutions Group can help you customize a flowmeter for your application, I got inspired to share a way you can custom configure our mass flow controllers and actually buy the flow meter online. Lets say you need a SmartTrak 100 digital air flow sensor for Argon with a max flow range of 28 slpm. Our selection wizard lets you enter this configuration and properly sizes the instrument for you.  In addition, you can then choose all the options you may want - digital display, fitting size, elastomer type, output signals and more. The selection wizard assembles the proper model for you and prices it out. From there, you can buy it if you want. Shop for a Smart-Trak 100 online and buy it today!
