摘要
The authors introduced a method to measure sample porosity based on the Archimedes law of buoyancy. This invention has many significant advantages,for example, high degree of intelligence, measurement accuracy, simple operation, automatically displaying the value of porosity, communication with computer and low cost and power consumption. The measuring accuracy of porosity less than 0.5% while MSE less than 1%, thus meet the need of porosity measurement.
