Model F PTFE flow meters

Model F PTFE single flow tube in-line rotameter

Downloads

Made entirely of PTFE, PFA, and PCTFE, the model F flow meter is excellent for high-purity applications or use with corrosive liquids. Units are available with a standard valve to monitor and control flow or without a valve to just monitor flow from 125 mL/min to 45 L/min water.

Flow meters are individually tested on a Mass Spectrometer Leak Detector and certified to a leak integrity rating of 1 X 10-7 sccs Helium or better.
