【Abstract】 Since the microcomputer has been used in measuring the flowrate of superheated steam,it is in condition to apply more accurate mathmatical model and to realize the temperature and pressure compesition for superb- eared stem flowrate.The measuring accuracy is increased greatly.Par- tial normal meters are saved in this microcomputer system.At present and in the future,it is able to increase economic effect and realize sc- ience management. Temperature,pressure and diferential pressure signals fromSsteam pipes are amplified,sampled and holded,A/D converted.After data processing,useful productive datas,such as instantaneous flowraate,in- stantaneous pressure,aceumulational flowrate,are completed and displied on the screen.It can also print out the data sheet in every integral hour according to the demand for production control.更多还原
