The days of simple analog mass flow meters with no variables but a zero pot are gone. Now you can get great flexibility with advanced digital mass flow controller technology like our Smart-Trak 100. But, because of this virtue, the flow meter also has many communication variables. We try to keep it simple by minimizing the need […]

Dilution is a special application in the world of gas mixing.  Basically, you are diluting a concentration of gas in an already existing gas mixture. Let’s say you have a gas mixture of 10% Ar/90% N2 and you really need 5 Ar/95% N2 for your application. The solution is to add more N2 to the the mix, […]

‘Kwik Kalucations’ with K-factors make gas mixing with a single gas mass flow meter simple. If you’re looking to improve flexibility and save money when it comes to gas mixing and blending applications, consider applying a “K-Factor.” A dimensionless numerical relation of a specific gas vs. air or nitrogen, a gas K-factor never changes. If K-factors will work in […]

In my last post, I discussed the important question of Mass or Volume flow measurement.   Today, I will discuss accuracy and the need to size your mass flow controller properly to assure the highest quality gas mixing and blending. Mass flow controllers are devices that have an accuracy of % of full scale (%FS).  That means […]

Mass or Volume: Important question! In my first blog post on gas mixing and blending, we saw that combustion is an important gas mix application. Combustion or burning is a chemical process, a reaction between molecules. To quantify the gas used we should count these gas molecules and not the space between these gas molecules. […]

Gas Mixing & Blending: Who, what and why? I am passionate about helping my customers obtain perfect gas mixing and blending!  I have been helping customers do this for over 25-years.  In this six part blog,  I want to discuss many of my experiences and aspects of gas mixing related to thermal mass flow controller technology. I want this blog to be […]
