Combination measuring devices for gas supply with integrated ethane detector

The EX-TEC HS 680 is perfect for detecting leaks in underground natural gas pipelines. Its multi-array sensor suite includes infrared for pinpointing the exact location of leaks along the pipeline. This system avoids unnecessary and costly excavations. Its optional integrated ethane-C-2H6 detector provides easy verification whether the gas leaking from the underground is a natural gas product from the pipeline or simply a natural occurring biogas (i.e., marsh or swamp gas).

Precision leak pinpointing is achieved using the optional oxygen-O2 sensor. The O2 sensor indicates the minimum O2 level while simultaneously measuring the maximum methane-CH4 level. This "minimum" with its smaller diffusion area in conjunction with the maximum methane indication provides easy pinpointing of complex leaks.

More Precise Gas Leak Pinpointing

If a gas leak has dispersed over a wide area, it is often difficult to precisely pinpoint the leak source.
Often the gas gathers under the surface and spreads over long distances.
The oxygen content decreases nearer the source of a leak and the methane gas level increases.
By utilizing the optional oxygen sensor the user can measure and display the oxygen minimum at the same time as the methane maximum. This minimum oxygen level, with its smaller diffusion area, makes it easier to locate complex leaks more precisely.
