West Jutland agriculture has long underground pipes leading to irrigation systems, farm buildings and distant paddocks. One section was laid when the system was established. Another was re-laid when the engine house was added, by an owner who has since sold the farm. None of them are marked anywhere, and the pipes that are marked are not always located where the drawing says.<\/p>

That's why a task out here rarely begins with listening. It begins with finding the pipe. If we don't know the process, we're listening in the wrong place, and a measurement without findings means nothing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

We trace pipelines and branch lines and mark the route in the terrain so that it can be drawn in later. On older plastic pipelines without tracer wire, ordinary tracing is not enough, and here tracer gas can find the route because the gas seeks up through the ground above the pipe.<\/p>

The search takes time, but it is rarely wasted. We often find outlets that no one remembered: an old branch pipe to a demolished building or a outlet to a watering place in a paddock that is no longer used. Such an outlet can remain under pressure for decades, losing water all the way, without anyone having had a reason to close it.<\/p>

The result is a drawing you can use again. The next time a foundation needs to be dug or a cable laid, the machine operator will know what lies underneath. And the next time consumption increases inexplicably, we can go straight to measuring.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The loss is felt most when the system is running. A hole that doesn't matter much in February costs pressure and pump hours in the middle of the irrigation season, when water has to be delivered to the cannon every day. The pump runs longer for the same result, and the pressure drops at the far end, long before anyone thinks of a leak.<\/p>

The season also has a technical side. When the system is in operation, there is pressure on the pipe, and a leak produces a measurable sound image. We therefore take the measurements when the operation provides the best conditions \u2014 sometimes during irrigation, other times during a break when consumption is not noisy.<\/p>

Therefore, the timing is worth considering. If you call in March, the progress can be tracked and the sections measured while the system is quiet, and a repair can be planned rather than having to rush through in July. If you have already lost pressure in the middle of the season, we will come out and narrow it down so that the excavation work is kept to one place.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A crop in the field does not change the method, but it does change the planning. We travel in the tramlines and in the tracks between the rows, and we place the probe where we can reach it without trampling the crop. If the conditions are so bad that the result is unreliable, we say so, rather than handing in a measurement that cannot be used.<\/p>

Once the point is found, it is marked in the terrain, and your contractor can dig there instead of following the pipe. DWI A \/ S<\/a> We do not dig or repair, but we are happy to give the measurements directly to the person who will be doing the work. In the event of an emergency break during the irrigation season, we often respond the same day; the emergency telephone number is +45 70 23 98 98<\/a>.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

When you need to check a wire yourself between two visits<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

If you have a large network of your own cables, it may make sense to be able to do the initial check yourself. Search equipment can be purchased or leased from us with service, and as an authorized distributor we are responsible for, among other things: Gutermann<\/a>.
If people want to be able to use it too, hold the DWI Leak Academy basic course in wiring and leak detection<\/a> at DTU Science Park in H\u00f8rsholm. There is theory about the sound image and about choosing a method, and there are practical exercises on the test track, where you look for pipes with known faults.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
