Description

Densimeter with adjustable balance weight

Technical Field

The utility model relates to a buoyancy formula densimeter technical field specifically is an adjustable densimeter of counter weight.

Background

The densitometer floats up or sinks according to the change of the gravity and buoyancy balance. When gravity is greater than buoyancy, the densitometer will sink. The weight of the densitometer is less than the weight of the same volume of water, so the densitometer is refloated. The reading of the densitometer is down and up, when it is immersed in different liquids, the volume-invariant indication changes, and iron sand or lead shot at the bottom of the densitometer is used to maintain equilibrium. The lower and upper densitometer readings are because P ═ ρ gh, the deeper the densitometer enters the liquid, the greater the pressure, and the lower and upper densitometer readings are.

The traditional buoyancy-type densitometer realizes the measurement of liquid with different densities through different counter weights, but when the liquid with different densities needs to be measured simultaneously, different buoyancy-type densitometers need to be replaced to adapt to the liquid with different densities (relative to the density of water).

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The following examples all employ a densitometer body having a mass of 20g and a volume of 30cm³The magnetic weight 5 and the magnetic disk 4 had a mass of 2g and the density of water was measured after adding 500g of water in a 1000ml measuring cup.

Example 1: measuring the density of water without adding the magnetic balance 5 and the magnetic disk 4

The densimeter body includes scale tube 1 and flotation pontoon, and the flotation pontoon includes upper cover 2 and stack shell 3, and the central fixedly connected with scale tube 1 at 2 tops of upper cover, upper cover 2 and stack shell 3 can dismantle the connection, are provided with the scale on the scale tube 1, and the "0" scale setting of scale tube 1 is in the middle section of scale tube 1. The densimeter body is placed in water, and the scales on the graduated tube 1, which are level with the water surface, are 0 scales.

Example 2: measuring the density of water containing salt (in this case, the density of brine is 110% of the density of pure water)

The density meter in the embodiment 1 is put into the brine in the embodiment, the density meter body can float out of the water surface more because of the higher density of the brine, and the scale of the upper water surface of the graduated tube 1 is +0.1 scale. The densimeter body is taken out, the upper cover 2 of the buoy is separated from the cylinder body 3, the magnetic wafer 4 is placed into the cylinder body 3, then the upper cover 2 is installed on the cylinder body 3, and density measurement is carried out again, the density of the densimeter body can be increased due to the magnetic wafer 4 added into the densimeter body, so that the height of the densimeter body floating out of the water surface is the same as that in the embodiment 1 (the scale of the graduated tube 1 which is level with the water surface is 0 scale).

Example 3: measurement of brine of unknown density

Since the density of the brine is unknown, there may be cases where: the density of the saline greatly exceeds the range of the embodiment 1, and the whole graduated tube 1 is above the liquid level by no degree

In the face of the above possible situation, it is necessary to add the magnetic disc 4 into the barrel 3, and adsorb a certain number of magnetic weights 5 on the bottom of the barrel 3 to increase the density of the densitometer body, each time one magnetic weight 5 is added, the density of the densitometer body is increased by 10% (compared with example 2), and after C magnetic weights 5 are added, the scale of the graduated tube 1 can be below the liquid level and can be read as B, at which time the density (specific gravity) X of the brine can be calculated as (1+ 0.1(C + 1)' (1+ B).

To sum up, this adjustable densimeter of counter weight sets up the detachable counter weight through setting up the counter weight in the bottom on traditional buoyancy formula densimeter's basis, when facing different density liquid measurements, only need the counter weight of adjustment densimeter bottom can adapt to different liquid density and measure.
