121.6KHz RFID Marker for Sewage Pipes | Underground Disc Beacon for Drainage Systems

1. Product Introduction

This disc-shaped RFID electronic marker (beacon) is specifically engineered for underground sewer and drainage networks. Operating at a frequency of 121.6 kHz, it is the ideal Tool for managing wastewater, stormwater, and combined sewer systems.

As a passive RFID locator tag, it requires no internal battery and is powered entirely by the electromagnetic field generated by a compatible handheld locator. Encapsulated in high-strength HDPE material, it offers excellent resistance to acid and alkali corrosion, making it suitable for the harsh, damp, and chemically aggressive environments typically found in sewage systems.

By deploying these markers at key nodes—such as manholes, pipe junctions, reducers, and outfalls—municipal maintenance crews can accurately pinpoint pipe depth and location without excavation using a low-frequency detector. This provides significant value for old pipeline surveys, fault detection, and pre-excavation safety warnings, effectively reducing the risk of environmental contamination from broken pipes caused by blind digging.

3. Functions & Applications

Pipeline Inventory & Mapping: Quickly locates the direction of underground drainage networks to establish or update GIS system data.

Fault Localization: Assists in rapidly finding the specific location of inspection points or abnormal pipe segments during blockages or breaks.

Excavation Damage Prevention: Scans construction areas to provide early warnings of major sewer mains, preventing mechanical digging that leads to pipe breaks and environmental pollution.

Critical Node Marking: Ideal for marking pipe start/end points, bends, branch connections, and road/rail crossings.

Continuous Route Tracing: Recommended for installation at regular intervals in complex sections to ensure continuous traceability of the pipeline path.
