High-grade Mass Flow Meter
MODEL 3100 SERIES
 The Model 
3100 Series Mass Flow Meter is a new, ad-vanced high-precision flowmeter
 developed based on the Model 3200 Series. The incorporated innovative 
capillary type flow sensor reduces pressure loss and ensures high 
response as well as ensuring stability.
