From January to December 2025, we supported fiber optic leak monitoring work for Company G's district heating supply and return pipelines.

Accurate leak location is essential when repairing urban heating pipelines. Fiber optic cables were installed to enable precise location measurement using DTS.

Sensing cables were fitted to both supply and return pipes. Test points for connecting optical patch cords were brought above ground so that DTS equipment could be connected for measurement.

This arrangement enables automatic leak measurement and identifies leak locations at one-meter intervals.

Topics: DTS, pipeline and district heating leak monitoring, distributed temperature sensing and automatic leak location.
