FLEXI-FLOW Compact: smart thermal mass flow meter for gases

FLEXI-FLOW Compact thermal mass flow meter for gases

The FLEXI-FLOW Compact is a thermal mass flow meter that measures gas flow and temperature in one compact instrument. Because it measures mass flow directly, readings do not need correction for changes in pressure or temperature. Its small footprint makes it ideal for desktop bioreactors, analytical equipment and fuel cell production.

Flow ranges from 0.1–5 mln/min up to 10–500 ln/min (N₂ equivalent)
8 pre-installed gases: Air, N₂, O₂, H₂, Ar, He, CH₄ and CO₂
Choose from 22 gases with Bronkhorst's FLUIDAT Onboard, using the free Bronkhorst FlowSuite software on PC or mobile
Bluetooth and USB-C for easy configuration
Digital output via FLOW-BUS and Modbus RTU

All 6 models are in listed below with their flow range and price.
