Natural gas undergoes a long process of transportation, pressurization, filtration, and pressure regulation from extraction to end-user use. In order to save urban space, many gas pipelines are buried underground, posing significant safety hazards.

Since the "6.13" gas explosion accident in Shiyan, Hubei last year, multiple gas explosion accidents have occurred successively in Shenyang, Dalian and other places in Liaoning, causing multiple casualties and arousing unprecedented attention from government departments and the public to the safety of gas pipelines.

How can pressure sensors serve as the first line of defense for urban gas safety?

The dynamic supervision, interconnection, and data sharing of gas pipelines and facilities cannot be achieved without sensors. Sensors are the bridge between objects and various data, and are the basic components of the perception layer of the Internet of Things. The sensor based front-end perception system for underground pipeline networks can not only provide reliable, effective, and practical automated online monitoring technology for gas companies, but also strengthen gas pipeline safety monitoring, shorten the response time for danger alarms, and quickly handle sudden alarm events in gas pipelines.

In gas safety systems, gas sensors are widely used, and combustible gas methane sensors, carbon monoxide sensors, and other gas sensors are indispensable and important components, as well as the first line of defense for safeguarding urban gas safety.

Pressure transmitters can monitor the pressure of gas pipelines in real time. Once a leak occurs, the pipeline pressure will decrease. If it exceeds the pre-set safe pressure value, an alarm will be triggered and abnormal positioning will be prompted.

The development and application of sensors and IoT technology can not only reduce the operation and maintenance costs of gas networks, but also improve operational efficiency. The monitoring and early warning, emergency rescue, and inspection and maintenance of gas pipelines are all developing towards intelligence with the participation of sensors and IoT technology.

With the development of the times, more and more cities are choosing to use IoT solutions to improve and protect residents' lives, and sensor technology will also make more contributions to urban safety!
