Intelligent Automatic Instruments in Natural Gas Flow

The rapid development of modern science and technology has significantly increased the speed of industrial development. The functions of intelligent automatic instruments are more comprehensive, and their application in natural gas measurement is more and more popular. As China attaches importance to the development of a green economy and environmental protection economy, the proportion of natural gas is increasing, and the requirements for the use and measurement of natural gas are more strict. Based on the accuracy and efficiency of intelligent automatic instruments, the measurement of natural gas flow has become an inevitable requirement of the development of the times. However, according to the current use situation, due to different regional development, some regions still use the traditional manual operation method to calibrate and measure the natural gas flow. The measurement efficiency is not high, the manual operation is difficult, and the accuracy is not high. Based on this, the majority of technicians need to conduct technical exploration and innovation and increase the promotion of intelligent automatic instruments.

Overview of intelligent automatic instruments

The intelligent automatic instrument is the product of modern science and technology, with more complete functions and higher accuracy. It can greatly improve the comprehensive efficiency of operation while reducing the difficulty of manual operation.

It has many functions, such as recording, displaying, controlling, measuring, alarming, etc. The automation instrument is an integrated system, which can convert the detected information in time and transmit accurate signals through the input and output process. The expressions of signals are also different, which can be roughly divided into two groups: instant domain and frequency domain. In addition, the signal transmission mode is divided into two forms, namely, continuous analog quantity form and discontinuous digital quantity form.

Composition of the measuring system of intelligent automatic instrument

Basic configuration of the measuring system of intelligent automatic instrument

The composition of the intelligent automatic instrument is relatively complex and contains multiple automatic components. Compared with other types of instruments, it has been very perfect in the automatic measurement system of natural gas flow. The intelligent automatic instrument is mainly composed of a multi-functional standard source, standard resistance, instrument controller, digital multimeter, voltage signal source, multi-functional calibrator, meter to be checked, and other components, which are indispensable. These components are not only the basic components of the intelligent automatic instrument system but also the guarantee that the intelligent automatic instrument can accurately measure the natural gas flow.

Analysis of the hardware of the intelligent automatic instrument

When technicians arrange and build their hardware equipment, they need to comprehensively consider a variety of factors, and the content is relatively complex and cumbersome. In the process of construction, technicians need to reasonably control the program control address and multi-function standard source of the checked table. In this process, technicians need to reasonably connect the computer system with the program control address to ensure that the instrument can systematically detect both during operation. Once both of them have faults or potential safety hazards during operation, the instrument will respond in a timely manner, Technicians can carry out targeted solutions according to specific situations. The normal operation of the instrument can not only facilitate technicians to find problems in time, reduce the occurrence of safety accidents, and greatly improve the efficiency of maintenance management but also detect the actual situation of manual operation, making up for the shortcomings of manual detection.

Analysis of software of the intelligent automatic instrument

The instrument software part is a collection of high and new technologies, which is more cumbersome and relatively accurate than the hardware. Among them, the multi-functional standard source has two major functions, specifically the automatic calibration function and the automatic printing function. In the actual operation process, its main work content is to transfer the corresponding value to ensure the stability and accuracy of the value transmission process. 

Technicians shall pay attention to the scientific and normative operation in the process of data comparison and analysis of monitoring instruments, and conduct data comparison and analysis in strict accordance with the analysis standards. After ensuring the accuracy of the data, the instrument to be tested needs to transfer the relevant data to the computer integrated system, the corresponding data analysis system conducts the secondary processing and analysis of the data, outputs the results, and finally transfers the relevant information to the printer for comprehensive sorting and printing of the calibration certificate. 

In addition, relevant staff should make key marks on the specific use methods, maintenance and repair functions, and verification methods of the measuring system of intelligent automatic instruments, sort out the specific contents, use rules, etc. of the measuring system by the relevant staff, and print them in written form, so as to maintain the operation of intelligent automatic instruments and obtain a qualitative and effective measurement in the measurement process, Strengthen the connection with the detection system.

Technical indexes and efficiency of the intelligent automatic instrument measuring system

Intelligent automatic instruments can effectively improve the accuracy and reliability of data. The testing speed of intelligent automatic instruments is fast, which is of great significance to promoting the working efficiency and the working speed of intelligent automatic instruments. When transmitting the value of the intelligent automatic instruments, the multi-functional calibration source has high accuracy and stability, so it is of great significance to improve the efficiency and stability of intelligent automatic instrument detection. In addition, the measurement system of intelligent automatic instruments can also automatically measure the natural gas flow. Even if the instrument has no interface, the measurement system of the intelligent automatic instruments can also realize semi-automatic measurement.

The measurement system of intelligent automatic instruments is simple and convenient to operate and has high test efficiency. It can also switch the range according to specific measurement conditions, and automatically analyze the data. Under different measurement requirements, there will be different backups and queries.

The application of science and technology is very important for the improvement of the comprehensive performance of the instrument. Our technicians continue to explore and research. Based on the analysis of the actual application of the instrument in natural gas detection in China, two detection methods, namely direct detection, and indirect detection are proposed to provide technical support for the actual measurement. At the same time, the combination of these two detection methods can give full play to the intelligent role of the instrument and the automatic detection function of the instrument, so that the detection work can be carried out in a reasonable, orderly, efficient, and high-quality manner, thus reducing manual operation, reducing the working pressure of staff, improving the accuracy of detection, and promoting the stable development of the natural gas industry.

Input process of intelligent automatic instrument

For the input process of intelligent automatic instruments, relevant process regulations need to be installed. When checking the data in the natural gas flow instrument, the technical skills of the auxiliary computer are required. After the relevant staff input the relevant data values, the computer background will select reasonable models and specifications to form a complete automatic form. However, some problems need to be noted in the input process. The staff must be careful when entering, to ensure that the data values entered are based and accurate, and to ensure that the relevant staff is proficient in computer operation.
