Chemical companies use a large number of storage tanks and metering tanks in material storage and production processes. 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 the electronic weighing module can be better solved.
1. Weighing module is applied to material metering:
Generally speaking, most of the current measurement of the liquid in the storage tank is measured by a scale or a flow meter. But both methods are measured in volume and then converted to weight based on the density of the liquid. Because the 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 companies because of their high price. Therefore, it is more economical and practical to use the electronic weighing module to directly weigh the weight of the materials.
2. Weighing module is applied to liquid level indication and control:
The liquid level is an important control parameter for the chemical production process. Generally, the liquid level indication is generally used to convert the liquid level signal into a standard electric signal or a gas signal to be transmitted to the control room in addition to the liquid level indicating instrument on site. However, in addition to the error of the liquid level caused by the change in density, the method may cause a false liquid level due to crystallization or clogging of the material, and may even cause an accident in severe cases. In addition, because the measuring part of the transmitter is directly in contact with the measured medium, for some corrosive media, expensive corrosion-resistant materials are required. The weighing module does not directly contact the measured medium, and none of the above disadvantages exist.
3. The weighing module is used in applications where the amount of material is strictly required:
There are some production processes that have strict requirements on the amount of feed. Many companies put the metering tank directly on the ground to control the amount of feed. However, on-ground balance inspection or inspection, it is necessary to hoist the measuring tank with lifting equipment, which is more troublesome. If the electronic weighing module is used, since the measuring tank itself is used as the scale body, there is no lifting problem, and the maintenance is convenient.
