title: [Design of new gas flow detector].
abstract: This paper presents a new gas flow measurement system, which works by calorimetric sensors and DSP wavelet transform signal processing. The system is achieved by specific hardware including flow sensors, voltage amplifier, A/D converter, DSP, heat control circuits as well as supporting software and algorithm. The main advantages of the scheme include its high precision, stable performance and high noise rejection. It can be applied to especially under small tidal volume and low-flow conditions.
