【Abstract】 The mculification methods of measurement errorsof turbine flowmeters involving to modify afterwards andat real time are presented. The schemes and systems ofmodification including that in density. pressurc. temperature and over range are recommended with the purpose ofdecrease in measurement errors. It is uscd as the refercncefor adding in the modification systems to the measurementsvstem of turbine flowmetrs.更多还原
