PROBLEM TO BE SOLVED: To accurately perform density measurement by the Archimedes method, even if a liquid of a density measuring object is corrosive such as high-temperature molten salt, while a liquid density gauge head is made of an inexpensive material and has an easily manufacturable structure.SOLUTION: The liquid density gauge head is immersed in the density measuring object liquid and obtains a density of the liquid by measuring a weight decrease due to a buoyancy and dividing by a volume. This liquid density gauge head has a weight 12 enclosed in a gauge head container 10 made of a corrosion-resistant material to the density measuring object liquid, the weight being held by filling a cushioning material 14 into an internal gap between the weight and the gauge head container. The gauge head container is preferably shaped thin and long, provided with a locking part for suspension at an upper end, and streamlined from a central cylindrical body to upper and lower ends. |
