with a triangular prism vortex shedder and a piezoelectric detector installed on the sample pipe.With oxygen volume fraction transducer
temperature resistance
MPXA6115A piezoresistive transducer
the gas flow
temperature
oxygen volume fraction and absolute pressure of the vehicle diluted exhaust emission are measured.MCU C8051F021 is used to process the signals
then them are transfered to human-machine interface by LabVIEW on the host computer.The calibration experiment shows the coefficient of flow meter is 1159.30
