Tips on how to select the best gas mass flow meter for your application

In our guide 'Flow Meters; a beginners' guide' we share some tips what to keep in mind when selecting your flow meter. In the selection of your instrument the following specifications can play an important role:
 

Gas flow meter specifications

• Accuracy: the accuracy of the gas flow meter depends on the model chosen. Not all meters possess the same accuracy, however, some applications do not require absolute precision. 
• Repeatability: Repeatability means the number of times (%) you get the same results running the same test or measurement under the same conditions. Sometimes repeatability of your instrument is considered to be more important than accuracy.
• Turndown ratio or rangeability:  the percentual range (e.g. 2...100%) or the maximum divided by the minimum measuring value (50:1) in which the specified accuracy is achieved.
