<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>AWM42150VH Airflow Sensor from Honeywell delivers fast response time and analog output. Honeywell AWM42150VH is laser trimmed for improved sensor interchangeability. This air flow sensor consumes less power and provides accurate, repeatable response. It comes with in-line printed circuit board terminals and is adaptable for use with higher flows.</p>
