PRESSURE OR AIRFLOW SENSORS? - Honeywell

At the simplest level, an airflow sensor, or more precisely a mass air flow sensor, is a device with two pressure ports where gas flows from one port to the other (see Figure1). Inside the sensor, there’s a sense element with a heated surface. As gas flows across the sense element, heat is transferred from upstream to downstream, asshown in Figure 2. This creates a thermal imbalance proportional to the …
