121.6KHZ Sewer Pipelines Marker Ball, Underground RFID Tag ED1500 have two models(ID or Non ID). It consists of a sealed shell containing a passive antenna - a low-frequency resonance circuit tuned to a certain frequency. The ID version integrates an ID chip. Depending on the resonant frequency and the color, the ED1500 are used to mark a wide range of underground facilities, such as telecommunication lines, power supply networks, cable television networks, water supply pipelines, wastewater networks, oil and gas pipelines, and so on.
1、APPLICATIONS
ED1500 can be installed at a certain interval, or at the turning of changing trend and at some event points, such as connection points, valves, well covers, T-shaped branches, etc. According to the project importance and project budget, the instralling density can vary from several meters to tens of meters, usually 10-20 meters.
