Description

Technical Field

[0001] The utility model relates to the technical field of float density meters, in particular to a float density meter. Background Art

[0002] A float density meter is an instrument based on the Archimedes principle, used to measure the density of a liquid. The working principle of the float density meter is mainly based on the Archimedes principle, that is, the weight reduced by the float in the liquid is equal to the gravity of the liquid displaced by the float. The greater the density of the liquid, the greater the buoyancy. Therefore, the change in buoyancy will cause the change in the up and down displacement of the float. However, the existing float density meter has certain inconveniences in use.

[0003] A float-type density meter is disclosed in utility model patent application number: CN201921434546.2. The float-type density meter improves the convenience during measurement, improves the accuracy of measurement data, and greatly improves the practicality of the float-type density meter. However, the float-type density meter is not convenient for cleaning the liquid attached to the surface after use, and is not convenient for subsequent storage. Moreover, the float-type density meter is prone to confusion when reading the numerical value, and cannot perform auxiliary recording, which easily affects the measurement accuracy. In addition, the solution container of the float-type density meter is not convenient for cleaning after use, which easily affects the subsequent measurement of other solutions. For this reason, we propose a float-type density meter. Utility Model Content
