The AWM1000 series mass flow sensor provides all of the outstanding performance benefits of the standard AWM2000 series in a more costeffective sensor platform. This device provides accurate, repeatable flow sensing. Sensor to sensor interchangeability specifications are approximately twice as large as compared to the AWM2000 series.
