Abstract: Using Coriolis sensor, computer and radio communication techniques can be realized the high accurate continuous measurement of the dencity,flow and pressure of cementing and drilling fluid on line. This measuring method is nonradioactive and direct. It overcomes the defects of the measaring methods of artificially weighing, radioactive densimeters, turbine flow meters, electromagnetic flowmeters, ul-trosonic flow meters etc. And it solves a difficult problem which has existed for several decades in measuring of the dencity, flow and pressure of cementing and drilling fluid in oilfields. The measuring system has been successfully applied in Liaohe, Dagang and Talimu Olifields
