| Abstract: | A tester for liquid density is an indespensable equipment in scientific researchand industry. the paper briefs a new method and a new meter for automatic measurement ofliquid density based on the buoyancy principle of Archimedes. The principle of the compoundsensor with a float--elastomer paralled plate capacitor is also discussed. The tester has the characteristics of steady, high sensitive, wide measurement range, high level of automation, autoconversion of density--temperature and autodsstorage. It can be widely applied in many fieldssuch as petroleum and the products from petroleum, chemical industry, light industry, metallury industry, food industry and medicine industry etc.. |
