Pressure Sensors Use in Smart Natural Gas Pipelines

Pipelines are the primary way to transport the natural gas from drilling sites to residential end users or gas stations. There are superior requirement on the closure of the pipeline in case of any leakage might cause hazardous accidents and mass loss due to the combustible and explosive characteristics of natural gas(90% content is CH4 methane). If any leakage might happen, it’s essential to alarm and find leakage location and cause in fast time as to solve it in time.

A large number of accidents show that the main factors leading to pipeline leakage and damage are corrosion, overpressure, excessive flow velocity, construction damage, material defects, etc. How to incorporate the safety of gas pipelines into intelligent management to effectively ensure the "health" of the entire life cycle of the gas pipeline network?

Through the help of Internet of Things, artificial intelligence, big data, industrial Internet, and other information means to collect and process pipeline life cycle data, provide support for intelligent analysis and intelligent decision-making, and use information means to realize pipeline visualization and intelligent management .

With the supporting system, remote monitoring, early warning and fast alarm can be achieved not only for security purpose, but also to intelligent adjustment to meet residential and other use demand. The installation of temperature, flow and pressure sensors in the gas pipeline can monitor the real-time pipeline pressure, flow and temperature parameters in the process of natural gas exploitation, transportation, metering and consuming, which can efficiently guarantee the safe operation of every gas system and is of great importance to realize automatic monitoring of 24 hours, automatic control of the gas pipe network. Safety and security and work efficiency can be greatly increased, operation and maintenance cost can be optimized as well.

Winsen is a sensor manufacturer with almost 30 years of development experience, providing pressure gas sensors, CH4 methane gas sensors, CO carbon monoxide sensor for process and end use monitoring.
