Bubble Flow Meter
Accurate Flow Rate Measurement Made Easy
KNOW YOUR FLOW
With any gas chromatography system, like our FROG portable GC, it’s important to be able to measure your flow rates. Defiant’s Bubble Flow Meter can help you do just that. The Bubble Flow Meter measures flow rates from pressure and vacuum.
Accurate flow measurements are essential for reliable chromatography. During sample collection, flow rates determine how much of analyte is collected for analysis. During analysis, flow rates govern the time analytes emerge from the column.
Measure the flow coming and going with the three stage bubble flow meter from Defiant Technologies. Now available for purchase online.
