(1) Distributed Control system DCS and distributed control system is a monitoring technology that integrates Communication, computing, control and display 4C(Communication, Computer, Control, CRT) technology.
(2) Large topological tree systems from top to bottom, in which Communication is the key.
(3) PID In the relay station, the relay station connects the computer with the field instrument and control device.
(4) Analog signal A/D-D/A mixed with microprocessing.
(5) An instrument is connected to a pair of lines I/O, and is hung to the LAN by the control station.
(6) DCS is the three-level structure of control (engineer station), operation (operator station), and field instrument (field control station).
(7) The disadvantage is the high cost, the company’s products can not be interchangeable, can not interoperate, the DCS system is different.
(8) For large-scale continuous process control, such as petrochemical, etc.
(9) Manufacturers :Bailey(USA), Westinghouse(USA), HITACH(Japan), LEEDS&NORTHRMP(USA), Siemens(Germany), Foxboro(USA), ABB(Switzerland)
With the continuous improvement of the degree of industrial production automation and the rapid development of computer microelectronics technology, all kinds of automation control systems in the industrial field of flow measurement requirements are increasing, so the flow meter from mechanical to electronic technology development, new flow meters continue to appear, flow meters in our national economy to play a more and more role with good prospects for development. Next, the small edition of the industrial mining network will introduce the relevant technical solutions for flow measurement in automation equipment around the use of flow detection and flow meters.
Flow, pressure and temperature are the three parameters for detecting objects, which are widely used in measurement. With the development of modern measurement methods, flow measurement is needed in the process of mass tautometry, such as power, metallurgy, chemical, petroleum, food and other industries, flow measurement is a common method of industrial measurement. Flow meter as a tool for flow measurement, according to the different measurement principles, measuring meters can be divided into many types such as: differential pressure type, displacement type, electromagnetic type, etc., not only the structure is more simple, the function is increasingly diverse.
Flow meter is widely used in process control, flow meter in the process control function is to detect the fluid flow in the sealed pipeline, if necessary, the flow measuring instrument and regulating instrument, actuator and other regulation system, the flow stable in the appropriate range, so as to achieve process stability. Therefore, the flow measurement instrument needs to meet the requirements of stable performance, reliability, strong anti-interference ability, short influence time and diversity of output signals in the process control. Below, through the application of the flow meter in the oilfield automatic metering system, the application of the flow meter in the power plant process system of the boiler air supply process two aspects of the application of flow detection and flow meter.
