<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>AWM5104VN airflow sensor from Honeywell features Venturi design and provides linear voltage output. This air flow sensor is active laser trimmed, which improves interchangeability to a great extent. This device has remote mounting capability for easy functionality.</p>
