by placing liquids of different concentrations in the first liquid tank 102 and the second liquid tank 106, it is firstly achieved that the liquids in the first liquid tank 102 are layered, the densities are different at different heights, after that, the raw materials are placed on the carrier plate 100, the carrier plate 100 is lowered to the bottommost surface of the first liquid tank 102, the carrier plate 100 is subjected to the buoyancy of the bottommost layer of liquid, the buoyancy is F1, which is the value with the largest buoyancy, after that, the first magnetic element 103 starts to be electrified, the current in the first magnetic element 103 is gradually increased, the magnetic force of the first magnetic element 103 is increased, after that, the magnetic field directions in the first magnetic element 103 and the second magnetic element 104 are the same, the second magnetic element 104 is subjected to the magnetic force, the magnetic force is defined as Fx, and the magnetic force Fx is increased along with the increase of the current;
when Fx+F1 is equal to the sum of the dead weights of the raw materials on the carrier plate 100 and the parts such as the carrier plate 100, the parts are stationary according to Newton's law;
when fx+f1 is greater than the sum of the dead weights of the raw materials on the carrier plate 100 and the parts such as the carrier plate 100, the carrier plate 100 moves upwards and has acceleration to accelerate upwards, when the buoyancy plate 101 reaches the penultimate liquid from the lowest liquid layer, the buoyancy becomes smaller, the buoyancy received by the buoyancy plate 101 in the penultimate liquid layer is defined as F2, and F2 is smaller than F1, which means that fx+f2 is smaller than the dead weights of the raw materials on the carrier plate 100 and the parts such as the carrier plate 100, and then the current on the first magnetic part 103 needs to be increased again, so that Fx received by the first magnetic part 103 is increased; increasing fx+f2 to be greater than the sum of the dead weights of the raw materials on the carrier plate 100 and the parts such as the carrier plate 100 will cause the carrier plate 100 to move upwards, and then the buoyancy plate 101 will reach the liquid of the last third layer from the liquid of the last second layer, the sum of fx+f3 will be again smaller than the sum of the dead weights of the raw materials on the carrier plate 100 and the parts such as the carrier plate 100, the magnitude of the current on the first magnetic part 103 needs to be increased again, so that values of columns such as F4, F5 and the like appear in a reciprocating manner, wherein the definition mode of F3, F4 and F5 is the buoyancy of the liquid of the last third layer;
through the mode, the Fx is controlled more accurately, the buoyancy is changed, the weighing is divided into a plurality of times of increasing the current of the first magnetic piece 103, and finally the weight of the raw materials is obtained through the current;
the specific further explanation is as follows: if only one liquid is used, the time required for returning the buoyancy plate 101 to the original position is long, or the weighing is inaccurate, meanwhile, other parts are supported between the buoyancy plate 101 and the carrier plate 100, only one liquid is used, the water discharge can be changed, the buoyancy can be changed, the size of the buoyancy change is the size of the water discharge change, the change is not obvious, the density of the liquid is reduced when the buoyancy plate 101 returns to the original position from bottom to top through layering of the liquid, the water discharge is also reduced, and the buoyancy change is more obvious; therefore, in the process of returning the buoyancy plate 101 to the original position, the directions of buoyancy and electromagnetic force are consistent, the sum of the buoyancy and the electromagnetic force is larger than the weight of the raw materials, if only one liquid is used, the buoyancy change is not obvious, the current can not be regulated for many times, the electromagnetic force is always larger than the weight of the raw materials, the weighing inaccuracy is further caused, the buoyancy change is obvious, the electromagnetic force needs to be regulated for many times, the influence of the liquid buoyancy on the resultant force of the upward movement of the buoyancy plate 101 is reduced, and in the last regulation, the buoyancy is smaller, the resultant force is more close to the electromagnetic force, the error is further reduced, and the weighing precision is improved.
As shown in fig. 1-2, 4-5: further, a bottom surface of the first liquid tank 102 is defined as a reference plane; the reference plane is perpendicular to the gravity direction; the projections of the first magnetic element 103 and the second magnetic element 104 on the reference plane completely overlap.

when in use, the liquid in the first liquid tank 102 is firstly transferred to the third liquid tank 109, and the sum of the liquid in the second liquid tank 106 is transferred to the first liquid tank 102, so that the change of the liquid in the first liquid tank 102 can be realized, namely the density of the liquid in the first liquid tank 102 can be changed, the liquid can be replaced when the raw materials with different weight degrees are faced, and meanwhile, the weighing precision and the weighing speed can be adjusted and changed.
