<p>The AWM720P1 airflow sensor from Honeywell features a compact package design with ultra stable null and full-scale performance. An airflow sensor measures the mass air flow rate entering a fuel-injected internal combustion engine. An engine control unit or ECU requires air flow measurement to provide an accurate fuel mass to an engine. </p> <p> This mass air sensor offers exceptionally low hysteresis and repeatability errors with less than 0.35% of reading. It consumes power lesser than 60 mW and assures a quick 6 ms response rate. It is suitable for portable devices and battery-powered systems. Other potential uses of this Honeywell Flow Sensor are mass flow controllers, leak detection, environmental climate controls, fuel cell controls, oxygen concentrators, spectroscopy and anesthesia delivery, among others. </p>
