Acoustic Leak Detection:
In very basic terms this lets us listen to leaks by using a microphone to amplify even the quietest of sounds. Acoustic equipment comes in several types that affect their cost and results produced.
The most basic is a ‘listening stick’ that you might see your water company using on the street, not particularly accurate, will only really find large leaks on the street and easily overwhelmed by ambient noise.
The first ‘proper’ acoustic equipment is analogue with a few filters (like tone controls) and has a basic microphone that covers most requirements.
We use a new generation of digital systems, these not only allow us to listen to the leak noise in a broad range, but we can slice the noise up into frequencies to reduce spurious noise like traffic and concentrate on just the leak.
The microphones also vary in cost and function. Low profile for under units, others sit on a small frame, some have a 1000mm spike for sticking in the dirt, and one is even called the ‘Elephants Foot’!
Each has a particular attribute for a particular job; UK Leak Detection carry all these to ensure we have the right tool for the job.
Regardless if it’s a ‘listening stick’ or our digital system, silence is golden and the quieter it is, the better the results, so please don’t be offended if we ask you to switch the TV or radio off etc.…
