TracerJect - tracer gas procedure Exact locating of leaks with tracer gas during running operations All locating procedures are ultimately based on acoustics. These procedures are increasingly finding their limits. Worsening factors include, for example, the increasing „environmental contamination“ by disruptive noise, even at night. Acoustic measuring points (fittings) are economised on. This extends the length the sound needs to bridge. Plastic lines are especially difficult, as they inherently conduct sound poorly. TracerJect: What is new in comparison to the classic tracer gas...

An approved, detectable gas with a hydrogen proportion of approximately five percent is added to the flow of water in the network section to be tested. The proportion of the additive is in turn oriented to the prevailing water temperature and the water pressure and lies between two and more than ten percent of the water flow rate. This amount can be easily absorbed in the water and causes no problems during running operation in terms of distribution. Even if the leak is located in the most unfavourable position, at the invert, the water-gas mixture exits there. Gas and water then separate...

Note: Depending upon the depth of the conduit and the soil structure, it can take up to approx. 0.5 – 2 hours until detectable gas can be measured at the surface of the earth. It should be ascertained that the line does not run at an incline in the flow direction. And this for as long as it takes for the gas to mix adequately. The tracer gas will otherwise be inadequately transported by the water and collect at the highest point. The injected gas is so pure that it can be consumed by humans. However, hygiene measures must be observed when feeding in. The feed-in hydrant must first be rinsed...
