| Abstract: | The vortex flowmeter is a new type of instrument for measuring flow, and it is a new kind of technique that the frequence of its output signal is calculated by adopting software method. This paper utilzes the computer simulating techique and realizes various algorithms of spectrum analsis by advance language to computer the simulating signals, and compares their diStinguishing features and results. This method ouvercomes the limitations and difficulties in the experiments, short6ns the period of developmenting the reality equipment. and provides the optical scheme. |
