Abstract: A flow sensor includes a mounting plate, bending plate, and a sensing assembly. The mounting plate is mounted to an internal surface of an air hose. The mounting plate is flexibly coupled to the bending plate, which is displaced in response to the flow of gas. The sensing assembly is positioned on the bending plate and includes a temperature sensor for sensing relatively lower flow rates during a thermal mode, and one or more displacement sensors for sensing relatively higher flow rates during a displacement mode. The temperature sensor outputs a thermal mode signal and the displacement sensors output a displacement mode signal. A flow sensing system includes the flow sensor, processor, memory, and a computer. The processor is responsive to the thermal and displacement mode signals. The computer is coupled to the processor and controls calibration of the flow sensor.
