How to Regulate the Pressure Intelligently in Natural Gas Pipeline Network System


As one of the important clean energy sources in China at this stage, natural gas is closely related to industrial production and people's livelihood. Therefore, the rational use of natural gas and its regulation and management has become an important part of urban construction. At present, China's natural gas storage and transportation are mainly by pipelines, and the huge natural gas pipeline system constitutes the main artery of urban operation.

Why does the natural gas pipeline network need an intelligent pressure regulation system?

The natural gas is flammable and explosive, whether the pressure and flow in the pipeline are always kept within a reasonable value range during transportation and use is an important factor for safe, stable, and continuous gas supply to downstream users. Therefore, accurate monitoring and regulation of the flow and pressure values in the gas pipeline is a key element to reduce the safety risk of the natural gas pipeline network system and improve the efficiency of management and regulation.

At the same time, with the development of smart cities, industrial Internet of Things, and other industries, the demand for intelligent monitoring in industrial control, social livelihood and other aspects is increasing day by day. The intelligent pressure regulation capability of natural gas pipelines has also become an essential part of the upgrading of the gas industry for precise management and efficient operation. Therefore, as an important part of the system, intelligent pressure regulation equipment has also seen a sharp increase in demand.

How to realize remote intelligent adjustment by the equipment?

Intelligent pressure regulation equipment is a relay station that accurately measures the flow and pressure of pipeline nodes. It feeds real-time measurement data back to the execution unit for operation, realizing global pipeline status monitoring and remote operation, to adjust the pipeline gas supply balance in the area in real-time.

However, decentralized pressure regulators are limited by the power supply, and intelligent pressure regulators require lower power consumption front-end devices. This puts forward higher and more applicable requirements for the sensors they use. Sensors used in intelligent pressure regulators need to reduce power consumption as much as possible on the premise of ensuring stability and accuracy, and the output of digital signals is more convenient for the reception and unified processing of the signal processing unit.

How to Choose the Right Sensor?

As mentioned above, high-precision, low-power consumption sensors are the core components of intelligent pressure regulation equipment. The sensors are the most front-end and precise components in the natural gas pipeline network intelligent pressure regulation system, performing important functions of real-time and accurate measurement. Thus, appropriate and specified sensor products are primarily for building a well-functioning intelligent pressure regulation system.
