Cylinder scales for liquefied petroleum gas enterprises to design and manufacture a set of fully automated multi-species mixing dosage weighing of three integrated production lines. The dynamic weighing scale, through the CC-Link fieldbus, together with PLC, HMI/IPC seamlessly form a three-in-one metering and dosage system, in which the industrial computer is connected to the factory ERP/MIS through HUB and Ethernet TCP/IP. The whole dosage process is carried out in strict accordance with the selected recipe ratio and flow, and has multi-level alarm records, completes the mixing of different raw materials to feed and logistic control, realizes the integration of management and control, and optimizes the performance and efficiency of process control. The integration of management and control optimizes the performance and efficiency of process control.

Cylinder scale adopts 2 sets of controllers with bus communication function, software platform through the SOL + WINCC software development of packaging control management system. The use of industrial control computers to achieve monitoring and control functions, through the programming software to realize the process and equipment control signals such as toxic and hazardous gas probe signals, liquid level, pressure, mixing, current signals: pumps and other facilities such as the state of the equipment, start and stop and other equipment data with the filling system process to form cause and effect conditions, to achieve the logic of interlocking control, and the entire control system is equipped with a four-with UPS power supply unit to ensure stable operation of the system. Reliable.

Liquid chlorine cylinder scales are accumulated and transferred to the weighing instrument through a junction box, and are displayed in real time through the conversion of the weight of the goods on the scale, and the serial communication transfers the displayed weight data to the PLC, which compares the collected weights with the weights set in the touch screen (or in the computer), in order to control the whole cylinder's action.

The cylinder weigher is a complete set of automation equipment for dynamic weighing and dosage control through electrical control management and visualization man-machine software configuration. The electrical control part of the system adopts Siemens PLC, which is programmed and controlled according to the production requirements; the software adopts man-machine group configuration, according to the process requirements, through the monitoring system and PLC program to control the weight and flow rate of the materials loaded into the weighing hopper, so as to realize the accurate measurement and dosage. The system has strong stability and high cost performance, and can provide accurate measurement data and control means for production control and management of various industrial sites.

Explosion-proof cylinder weighing the use of RFID weighing technology for intelligent management, through the antenna to the electronic tag microwave query signal, the electronic tag is read-write microwave energy activation, receive microwave signals after the answer and send out the return signal with the label data information. Adopting radio technology to realize the identification of static or moving objects, to determine the identity of the object to be identified, extract the weight of the object to be identified and other information for the purpose.

Explosion-proof cylinder scale adopts modern sensor technology, electronic technology and computer technology integration of electronic weighing device, to meet and solve the real-life requirements put forward in the rapid, accurate, continuous, automatic weighing, and at the same time effectively eliminate human error.
