The MXR-500 quantitative loading control system is a modern loading system jointly developed by our company based on the current situation of petrochemical storage and transportation. The system mainly consists of quantitative loading control instruments, flow meters, control valves, liquid level switches, and electrostatic grounding detection devices as the main hardware. Suitable for automatic loading of car tank trucks and train tank trucks, it can effectively complete various tasks such as parameter setting, data collection, flow rate compensation, quantitative control, program operation, overflow, anti-static interlock control, operation monitoring, report printing, etc. during the loading process; The system has a communication interface with the upper management computer and can be networked with computers outside the system. High loading accuracy, fast speed, elimination of human errors, reduction of environmental pollution, and high efficiency and energy saving.
