The AWM5102VN is a Microbridge Mass Airflow Sensor features Venturi type flow housing. This airflow sensor measures flow as high as 20 standard litres per minute (SLPM) while inducing a maximum pressure drop of 2.25-inch H₂O. The Microbridge chip is in direct contact with the flow stream, greatly reducing error possibilities due to orifice or bypass channel clogging. This sensor contains circuitry which performs amplification, linearization, temperature compensation and gas calibration. A 1 to 5VDC linear output is possible for all listings regardless of flow range (10 SLPM) or calibration gas (nitrogen). This calibration is performed by active laser.
