ABSTRACT:
The measuring device has bobs 10, 17 suspended from a weight 12 with wires 11, 16. The hook 13 of the weight 12 is hung from a suspensor thread 15 extending downwards from a balance 14. The weight 12 may be omitted by using the upper bob 10 for dead weight. The bobs 10, 17 and the wires 11, 16 may be coated with a coating layer unreactive to the melt 19 whose density is to be measured. The weights of the measuring device is measured by the balance 14 under the first condition that the lower bob 17 is immersed in the liquid 19 and the second condition that the bobs 10, 17 are both immersed in the liquid 19. The density of the liquid 19 is calculated from the two measured values without the influence of the surface tension of the liquid 19 applied to the wires 11, 16.
