Acoustic Leak Detection System

We are a prominent Importer and Supplier of precision engineered Acoustic Leak Detection System. Acoustic Leak Detection System, available with us, has been installed worldwide on pipelines including gas, liquid and multiphase flow. The Acoustic Leak Detection System is known for its reliability. Clients can avail Acoustic Leak Detection System from us at the industry leading prices. Working Principle At the instant of a breakdown of the pressure boundary (leak), the release of the elastic force couples with the system fluid to create a transient acoustic wave. This acoustic wave travels outward from the source at the speed of sound for that fluid, guided by the pipe wall, to be detected by sensitive acoustic sensors situated at the ends of the pipeline and some intermediate valve sites. From times of arrival of the acoustic waves at different sensor locations, the location of the leak is determined. With the use of GPS receivers, the leak detection and time stamping functions are performed at each local processor, the Acoustic Leak Detection System will continue to detect leaks in case of communication fault or loss of communication. Advantages Of Acoustic Leak Detection System

• Minimal time to detect and locate leaks, typically within one minute of leak occurrence
• Very accurate leak location calculation, typically to within +/- 30 meters or +/- 0.1% of monitor span
• Extremely low false alarm rate (typically less than one per year)
• Used for most of pressurized pipelines, including single phase liquid, single phase gas and multi- phase flow pipelines
• Very sensitive, detect and locate very small leaks
• Detect leaks with or without (shut-in) flow, steady state as well as various transient operations (valve open/close, pump shut down/startup, flow increase/decrease, etc.)
• Very easy to install and operate
• Continuous leak detection with loss of communications
• Minimum maintenance, no calibration required
• Used for automatic valve shut off upon detection of leak
• Decreased risk to people and environment
• Reduced financial loss for product and for clean-up in case of accidents

Acoustic Leak Detection Systems (ALDS) employs proprietary hardware for on-line real-time leak detection and associated hardware and software for supervising communications, structuring databases, data analysis, decision-making, report and display generation and issuing alarms. Acoustic Leak Detection Systems employ combinations of radio, fiber optic and hardwire communications with either personal or mainframe computers for operator interface. Applications include liquid, gas and multi-phase flow pipelines, and consist of single transmission lines, networks, gathering lines, subsea lines, single and multiple product transfer lines. The WaveAlert® system is the only leak detection system with an establish record of not only detecting leaks but automatically shutting in pipeline valves to limit environmental damage and possible casualties. This can only be accomplished with a minimum number of false alarms. Why We Need Pipe Line Leak Detection System? Rising oil prices, environmental awareness and focus on prevention of catastrophic accidents have brought to the forefront the need for a truly reliable, fast, accurate, and sensitive on-line real-time leak detection system (LDS). In evaluating on-line real-time leak detection systems for environmental concerns, four important criteria are applied, namely: detection time, sensitivity, leak location accuracy, and most importantly reliability (or false alarm rate). In addition, factors such as the ease of system installation, operation and maintenance are taken into account. Based on these considerations, Acoustic Leak Detection System has shown to be the most effective and reliable leak detection system for single phase gas, liquid, as well as multiphase flow pipelines. Does Acoustic Leak Detection System really detect the Leak? Due to its low false alarm rate and reliable performance in actually detecting and locating leaks under various operation conditions, Acoustic Leak Detection System is the only LDS successfully used for automatic valve shut-off upon detection of leak. For example, in November 2000 a WaveAlert® VII system installed in Australia detected and located a leak on an LPG pipeline and automatically shut-in the pipeline within one minute of leak occurrence preventing potential casualties and environmental disaster.
