[0002] Densitometer, also known as density meter, is composed of a weighing system, density calculation software program, and accessories for density measurement. It is a device that can test liquid density simply and quickly by applying Archimedes principle. To measure the density of a substance, the buoyancy method, water displacement method, and specific gravity bottle method can be applied according to Archimedes principle. When an object is completely immersed in a liquid, the volume of the object is required to be equal to the volume of the displaced liquid.
[0003] A density meter is generally composed of a density meter body, a bracket, a storage table, a hook and weights. It can measure the density of the liquid to be tested. Due to the use of calculation software, the entire process does not require manual recording of various data. The calculation software will automatically record and calculate, which is more efficient and has smaller errors.
[0004] The following shortcomings were found during subsequent use:
[0005] 1. The beaker filled with oil is simply placed on the storage table. If it encounters external force, the oil will easily spill out, which is difficult to handle and will affect the subsequent density measurement;
[0006] 2. The hook is mounted on the bracket without corresponding fixing means. During measurement, if there is shaking, the weight hanging on the hook will easily collide with the wall of the beaker, which will cause errors in the density measurement.
[0007] Therefore, in view of this, the existing structure was studied and improved, and a density meter for measuring oil was proposed. Utility Model Content
