The working principle of the system The body of the volumetric tube is a closed volumetric standard made of steel pipes. Its basic volume value refers to the volume of the pipe section between the start detection switch D1 and the end detection switch D2. The volume value is measured by the authorized unit of the State Bureau of Technical Supervision in accordance with the national verification re...
How the system working Use a volumetric tube to calibrate the flowmeter. In order to accurately reflect the repeatability of the meter at each flow point, according to the national standard GB/T13282, the basic volume of the volumetric tube should be selected according to the following principles: In the formula: VQ——basic volume design value (m 3 ); Qmax—&mda...
Software process Practical application After the system was installed and debugged, it was officially put into use in October 1999. It has been running stably for more than two years and has calibrated nearly a hundred flowmeters (times) without any problems in the control system. Practice has proved that the system has a high degree of automation, and all performance indicators fully meet t...
Application of PLC, DCS and FCS in metallurgical process control In metallurgical production, the process control system completes the detection, display, recording, adjustment, control, alarm and other functions of the generated process parameters. play an extremely important role. Its characteristic is to control the real-time production process, the control process is complicated, the process l...
The control scale and complexity of the process control system 1. According to the control scale and complexity of the process control system For different metallurgical production processes, the control scale and complexity of the process control system are different. Usually, DCS is preferred when the process control system is large in scale and high in complexity. Because the system is develope...
