蜗壳压差法在实际测流过程中的问题探讨

Discussion on the Problem in the Real Current Measurement with the Volute Pressure Difference Method

针对蜗壳压差法在实际测流过程中所遇到的问题 ,提出了阻尼稳压及自动排气的 2种办法 。

For the problems in the real curr e nt measurement with the method of volute pressure difference,two solutions dampe d pressure regulation and auto gas purging were proposed.The methods are simple and practicable.
