A piezometric densitometerincludes two (short and long) piezometric tubes immersed to liquid under investigation to different depths and connected to block for air supply, differential manometer plus chamber of which is connected to long piezometric tube, and the minus chamber through safety equipment to the short piezometric tube. To the design of densitometer introduced are third (additional) piezometric tube, second differential manometer and controller of the ratio of air flow rate, and the design of the first and the second differential manometers are chosen with account of transformation of results of measurement of those to unified output signals. Additional piezometric tube is immersed to same depth with the long piezometric tube and is connected to the plus chamber of the second differential manometer, the long piezometric tube that is connected to the plus chamber of the first differential manometer is along with that connected to the minus chamber of the second differential manometer. |
