Mass Flow Online - Model FF-109 FLEXI-FLOW 50 ln/min -Smart Thermal Mass Flow Meter for Gases

With free software Bronkhorst FlowSuite you can add one of the 22 available gases or create mixtures on to the instrument.

This way you have a multi fluid instrument for your application:

• C2H2, Air, C3H4 #1, Ar, CO2, CO, C3H6 #1, D2 #1,
• C2H6, C2H4, He, H2, Kr, CH4, Ne, N2, N2O, O2, C3F8,
• C3H6 #2, C3H8, C3H4 #2

You can easily connect the instrument to your phone via Bluetooth and use it with the app.

Alternatively, the instrument can be connected to a PC using the appropriate cables. Read here to learn how to connect the FLEXI-FLOW to your PC.
