D6F MEMS Flow Sensors

The Omron family of D6F MEMS (MicroElectroMechanical System) Flow Sensors includes intelligent, compact models capable of measuring flow velocity and mass flow rate movement with highly repeatable accuracy. Mass flow rates from 1 LPM to 50 LPM (liters per minute) and high sensitivity are achieved with the MEMS Flow Chip.

Features Small size due to MEMS technology Flow Sensors can be used with most medical, inert welding, and combustion gases Excellent repeatability and accuracy
