When and Why to Use an Electronic Flowmeter

Flowmeters are often seen as essential tools for gas chromatography labs. But, since modern GC instruments feature advanced pressure controls, valves, and built-in flow measurement software, is it necessary to have a handheld electronic flowmeter device? In this Restek Tip, we share some situations where an electronic flowmeter can be used and look at the benefits of using one instead of your instrument. ----------------------------------------------------------------- Contents 0:00 GC Flowmeters 0:34 Why Use a GC Flowmeter? 1:14 Measuring GC Column Flow 1:35 Measuring Fuel Gases 1:56 Calculating Split Ratios 2:12 Verify Results ----------------------------------------------------------------- Additional Resources Restek Electronic Flowmeter FAQ | https://www.restek.com/faq_flow A Primer on Gas Flow | https://www.restek.com/Technical-Resources/Technical-Library/General-Interest/general_GNAN1402 ----------------------------------------------------------------- Restek Recommended Tools & Parts Restek ProFLOW 6000 Electronic Flowmeter | https://www.restek.com/flowmeter ----------------------------------------------------------------- Connect with Us Comment on this video and subscribe to Restek's YouTube channel today at https://www.youtube.com/user/RestekCorp Website: https://www.restek.com LinkedIn: https://www.linkedin.com/company/restek-corporation/ Facebook: https://www.facebook.com/RestekCorporation Twitter: https://www.twitter.com/Restek
