<p>An airflow sensor is a device used to measure the mass flowrate or mass of air entering a fuel-injected internal combustion engine. The engine control unit (ECU) requires the air flow measurement to stabilize and provide the accurate fuel mass to the engine. This Honeywell Flow Sensor is used in a wide range of applications including gas metering, gas chromatography, gas analyzers, medical respirators and ventilators, leak detection equipment, low vacuum control, and oxygen concentrators, among others.</p> <p>AWM3303V Airflow Sensor from Honeywell features dual Wheatstone bridges to control airflow measurement. Honeywell AWM3303V is laser trimmed for improved sensor interchangeability. This flow sensor comes with low differential pressure sensing capability and can deliver flow sensing up to 1.0 SLPM.</p>
