Application of weighing modules in large storage tanks

In addition to the above mentioned special applications, weighing modules can be significantly used in other special applications in the production process of dosage systems in the following three points:

The first point: the weighing module can be used for the precise measurement of liquid tanks in the production process of automated dosage systems.

Currently automated dosage system for liquid storage and irrigation material measurement devices are mostly flow meters, metering pumps, level instrumentation and other products, of which the flow meter has a high measurement accuracy, easy to install and commissioning and other characteristics, generally installed in the storage and irrigation material import and export pipeline, used to measure the pipeline fluid instantaneous flow and cumulative flow, mostly used in the flow measurement and weighing system, but the disadvantage is that the accuracy of the measurement by the installation conditions and temperature Changes have a greater impact on the calculation of the weight of the material stored in the irrigation needs to be accessed through the inlet and outlet flowmeter calculator or DCS system to calculate the accuracy of its impact by a variety of factors, the current market for the application of electromagnetic flowmeter, mass flowmeter, ultrasonic flowmeter and other products, but the product price is expensive, calibration difficulties, the general business is less commonly used.

In recent years the use of weighing modules as a reactor weighing material precision measurement has been widely adopted by the chemical plant production process enterprises, which is characterized by easy installation, inexpensive, not subject to the site and the shape of the storage and irrigation limitations, and high accuracy of measurement, easy to calibrate, can be used as a storage and irrigation of materials in and out of the library for measurement, but also can be used for the process of flow control, in general according to the shape of the tanks and the installation of different ways to choose 3 Generally, according to the shape of the storage tank and different installation methods, 3 or 4 load cells can be selected to complete the process, especially suitable for chemical plants in the production process of quantitative feeding system occasions.

The second point: it can be significantly applied to the level measurement and control in the production process of weighing system.

Generally speaking, there are many devices used for level measurement in the production process of chemical plants, such as differential pressure level meter, ultrasonic level meter, magnetostrictive level meter, float level meter and so on.

Weighing module in the chemical plant production process of some special occasions in the level measurement system can be a great help, for example, in the commissioning without the use of weights calibration, just according to the level of empty irrigation calibration zero, in greater than 50% of the total amount of any one point according to the level of height proportional to the calibration of the output current can be completed to complete the instrumentation calibration, instrumentation to complete the calibration of the output current with the height of the level of the basic linear relationship.

The third point: can be significantly applied to automatic dosage system reaction kettle in the liquid density measurement and control

In the chemical plant production process in the salt chemical industry and lithium chloride production process often need to control the reaction kettle in the liquid level and density of two parameters, in the control of the liquid level must be how to detect the density of the liquid is the process of technical personnel headache, the use of on-line densitometers, ordinary products are difficult to overcome the impact of high temperature and high pressure, and the price is also very expensive, the measurement accuracy is not high, it is not easy to calibrate, to the continuous production of a certain impact. It is not easy to calibrate, which brings certain influence to the continuous production. The use of electronic weighing module can be a good solution to this problem, weighing module selection principles and dosage system and filling system is basically the same, according to the shape of the reactor to install 3 or 4 weighing module, through the weight transmitter into 4 ~ 20mA current as the system display and control of input signals, when the level of reaction kettle when the raw material will be a certain brine weight as the density of the zero point for the calibration, and through the weighing instrument or DCS, the density of the raw material will be calibrated, and the density of the raw material will be calibrated. And through the weighing instrument or DCS system is set as the initial density value, when the weighing module detects the weight in the reaction kettle rises to a certain value, such as rising more than 20% (to ensure that the liquid level must be certain), the weight value of the point can be calibrated as the second point of the density value, at this time, the output current is basically a linear relationship with the density value, in order to ensure the accuracy of each point in the calibration of the liquid must be sampled before the detection of density. In order to ensure the accuracy of each point, it is necessary to sample the liquid to check the density before calibration. At this time, the liquid level signal of the kettle is used as the control signal of the feed valve of the kettle for the automatic adjustment of the liquid level parameter, and the output signal of the weight transmitter is used as the control signal of the discharge valve of the kettle for the automatic adjustment of the density parameter, so that the whole dosage scale realizes the function of automatic adjustment in the continuous production process. Adopting the weighing module as the density detecting device is characterized by low cost, easy installation, high detecting accuracy, etc. It has unparalleled advantages compared with other types of densitometers.

BS Explosion-proof weighing module
Weighing module is a device that can convert physical or chemical quantities into electrical signals that can be easily used. It can convert input variables into signals that can be measured, and sense the change of acceleration force. Acceleration force is the force that acts on an object during acceleration. All kinds of gravity changes such as shaking, falling, rising and falling can be converted into electrical signals by G-sensor, and then converted into electrical signals or other required forms of information output according to certain rules after calculation and analysis by microprocessor, so as to meet the requirements of information transmission and information output.
