How to Find a Water Leak

Our highly trained engineers at L.D.S. Leak Detection Specialists Ltd. will choose the approriate testing and inspection process specifically chosen to suit your home or commercial business to find the leak.

Our engineers at L.D.S. carry all the latest technology in leakage detection. We have listed the main Leak detection methods and equipment below. Inspection cameras. Protimeter mms damp meter survey kits, pressure gauges both hydraulic and digital and salts diagnostic kits also form part of the L.D.S. engineers equipment.

Leak Detection Methods to Find A Leak

Acoustic profiling uses ground and pipe sensitive microphones to enhance the sound of the leak. This method can help in pinpointing precise leak location.

Is a way of finding and pinpointing leaks in water pipes. A leak in a pipe under pressure creates noise that travels through the pipe walls, the surrounding ground and along the contents of the pipe. Correlators are a very accurate sound testing device which are used to identify the acoustic frequency caused when a pipe is leaking. The correlator uses two identical sensors located along the pipe to calculate the leek location by logging the signal delay, sensor distance and the sound velocity.

Tracer Gas
The trace gas, a safe mixture of hydrogen and nitrogen, is introduced into the pipe with the suspected leak. The gas, is the lightest in the atmosphere and is made up of of small molecules. The gas will exit at the leak and make its way to the surface where it is detected using gas sensitive detection pobes.

Thermal Imaging
Thermography is the use of an infrared imaging and measurement camera to see and measure thermal energy emitted from an object. Thermography cameras can identify problem areas that can’t be seen with the naked eye, detecting hidden water leaks. The infrared inspection camera can detect not only hidden water leaks and their origin, but also moisture that cannot be physically reached with moisture meters. Read more

Pipe, Cable and Metal Detection and Tracing
Often the exact position of pipes and cables is unknown due to innacurate or non existant network plans. In order to carry out precise water leak detection and to avoid damage to utilities and operators during excavations, it is essential to know the precise position of all services. We use high performance equipment which can locate and trace buried pipes and cables.

Network Monitoring with Noise Loggers
Noise Loggers are used for early detection of leaks in water supply networks.The longer it takes to identify that a network is leaking the more revenue is lost and the greater the loss of precious water resources. In addition to the more conventional methods of leak detection the installation of permanent noise loggers has proved to be a cost effective tool in early identification of water loss. By permanently monitoring sections of the system, which have previously been proven leak free, it will alert you when a potential leak does develop. Read more .

Course Synopsis

Music Production – MP100/8.5
Introduces students to the basic principles of audio recording and music production through classroom lecture, and handson training, as well as guided and individual studio projects. Students learn about the principles of sound, signal flow, microphones, mic placement techniques, dynamics, large format consoles, and the entire recording process. Student must exhibit a working knowledge of audio concepts, facilities, and gear handling as a requirement for completion. Emphasis is on training for an entry-level position as an assistant engineer in a music production studio.

Music Production – MP200/9.0
Introduces students to the Solid State Logic 4000 E/G+ series console and computer, including theoretical console and computer study, pre-production, tracking, overdubbing, and mix down sessions. Students will practice extensive signal flow overview through application classes and clinics. Students will continue to refine the skills necessary to obtain a job in the audio industry through advanced recording and mixing clinics, using analog and digital recording mediums, and adding skills like automation. MP200 also exposes students to Post Production and Commercial Production. Through hands-on applications, students will recreate all audio elements for film and television projects using professional production techniques designed to prepare them for a wide variety of recording industry employment options.

Music Production – MP300/1.5
Introduces students to hybrid console technologies using the SSL AWS948 console and Pro Tools recording software. Students will engage in tracking, overdub, mixing, and mastering clinics. Clinics will start to introduce the concept of a “producer” into the room, providing students the most accurate real-world recording scenarios. MP300 classes will also teach students to start planning for internship and industry life, incorporating classes on personal networking, budgeting, and job interview techniques.

Audio Business – AB100/1.0
Offers students an overview of the music industry, including copyright law, publishing and song income, contracts, record production, record labels, scams and dangers, personal finance and many other industry-related topics.

Audio Business – AB200/1.0
Continuing the concepts introduced in AB100, AB200 classes focus on a deeper examination of the audio industry. Includes in-depth study of songwriting, recording and other contracts. Also examines trademark law, practical application of copyright law, contracts for engineers, career planning, interview techniques, industry etiquette, industry-topic forums and discussions.

Core Technologies – CT100/3.5
Provides students with a basic understanding of various technologies that are fundamental to many disciplines within audio production. Basic electronics, analog and digital audio, control protocols and fundamental computer and networking technologies will be explored in the context of audio production. Students will also see and use these systems in a variety of practical applications. During this course students will make extensive use of their laptop recording package, including Apple’s Logic Pro audio production software.

Pro Tools – PT100/4.0
Utilizing the latest Pro Tools software, students will learn about session and system configurations, audio recording, track and file management, session navigation, and editing of dialog, music, and sound effects.
