| Abstract: | A new method about the standard throttling set on-line iterative measurement is proposea, mat is based on flow measurement using the traditional standard throttling set. This method can measure flow according to the applying condition not designing condition. It overcomes the impact of parameter variation, low precision, narrow measurement range etc. , and makes the precision reliable and improves the measurement range ratio. |
