Pipeline leakage will not only cause resource loss and environmental pollution, but also oil, natural gas and other leakage products will even cause fire, so it is very important to monitor the pipeline in real time, find the leakage and predict the hidden danger in time. The traditional leakage monitoring methods can't locate accurately, can't predict the hidden danger of leakage in advance, and have high false alarm rate.

Advantages of the system:

    The distributed optical fiber temperature measurement system lays the sensing optical fiber around the pipeline. When the pipeline leaks, the temperature of the gas or liquid transported in the pipeline is different from the ambient temperature of the pipeline, and the temperature change of the surrounding environment is monitored in real time. Find out the leakage in time. Dt-412c has a measuring distance of 40km and a spatial resolution of 1m, which can accurately find the leakage situation and locate the leakage point.

Technical features:

1、No electricity detection, intrinsically safe explosion-proof
2、Adopt the ring monitoring method created by Danone, with high system reliability
3、Differential constant temperature compound alarm, accurate and reliable alarm, no false alarm
4、The system can accurately locate the temperature measurement point and fault point, and win time for equipment maintenance and emergency repair
5、The system has self checking function, which can monitor its operation in real time and output the sound and light signals of fault alarm
6、The temperature measuring optical cable used to detect oil tank fire is an anti-static optical cable specially developed by our company for fire detection in oil depot area. Its outer sheath material is metal, which can avoid static electricity between the pipeline and reduce the possibility of fire
7、The system has simple structure and convenient installation and maintenance
