The sensing chamber can be located after a blower and/or mixer. The sensing chamber can include an ultrasonic transducer, a \" temperature sensor, a heated temperature sensing element, and/or a gas concentration sensor. A flow path of gases used in conjunc - 0 tion with the sensor system prevents unwanted vorticity in the flow of gases that can create anomalies in measuring flow.
