Application of Weighing Module in Chemical Industry

Chemical companies use a large number of storage tanks and metering tanks in the process of material storage and production. However, two problems are commonly encountered, one is the measurement of materials, and the other is the control of the production process. According to our practice, the application of electronic weighing module can be a better solution.

1. The weighing module is applied to material measurement:

Generally speaking, most of the current measurement of liquid in storage tanks is measured by a ruler or a flow meter. But these two methods are measured by volume, and then converted into weight based on the density of the liquid. Because density is related to temperature and other factors, the error is relatively large. Although there are mass flow meters at present, they are rarely used by ordinary enterprises because of their high prices. Therefore, it is more economical and practical to use electronic weighing modules to directly weigh the materials.

2. The weighing module is used for liquid level indication and control:

Liquid level is an important control parameter in the chemical production process. In addition to the on-site liquid level indicator, the liquid level indicator usually uses a transmitter to convert the liquid level signal into a standard electrical signal or a gas signal to be transmitted to the control room. However, this method, in addition to the aforementioned error of the liquid level caused by the change in density, may also cause false liquid level due to material crystallization, blockage, etc., and even cause accidents in severe cases. In addition, because the measuring part of the transmitter is in direct contact with the measured medium, for some corrosive media, expensive corrosion-resistant materials need to be selected. However, the weighing module does not directly contact the measured medium, and none of the above shortcomings exist.

3. The weighing module is used in occasions with strict requirements on the feeding amount:

Some production processes have strict requirements on the amount of feed, and many companies put the metering tank directly on the ground to control the amount of feed. However, when the ground scale is overhauled or inspected, it is necessary to use hoisting equipment to lift the measuring tank down, which is more troublesome. If the electronic weighing module is used, because the measuring tank itself serves as the scale body, there is no lifting problem, and the maintenance is more convenient.
