High throughput leak detection
How can you improve leak testing precision and throughput? Various methods have historically been used to check leaks in systems and components—from bubble tests to rotameters and pressure loss detection. While these traditional methods have their place, they each have serious drawbacks in accuracy, throughput, and automation. You may be faced with more demanding situations that call for ...

Development of a long duration, free swimming, inline acoustic leak detection inspection tool
Abstract Acoustic leak detection inspection tools have become a common technique to identify minute pipeline leakage before the leak and the defect producing it can become a larger problem or even a rupture level event. While these inspection tools only identify small defects once they reach the through wall stage and result in leakage, they can be an effective means of demonstrating the ...

GPS Verification for Leak Detection and Repair (LDAR)
Pen and paper, as well as barcode scanners with handheld computers, have been used in the past to record locations and times for each inspection, but that information can be easily falsified. Many companies face the critical problem of not being able to verify and prove that data was taken correctly and accurately by field technicians. Audits have revealed false numbers that were recorded in ...

PERMALERT® Leak Detection System: Protecting Data Centers Since 1990
As data centers are getting increasingly larger in scale, efficient HVAC and cooling systems have become high priorities for major data center operators. To ensure maximum uptime of these critical supporting systems, effective leak detection and monitoring solutions are essential. The majority of leak detection systems in the market today are based on resistive technology that relies on a liquid ...

Risk-based sensor placement methods for burst/leak detection in water distribution systems
The optimal placement of sensors for burst/leak detection in water distribution systems is usually formulated as an optimisation problem. In this study three different risk-based functions are used to drive optimal location of a given number of sensors in a water distribution network. A simple function based on likelihood of leak non-detection is compared with two other risk-based functions, ...

EPA Method 21 Leak Detection Using Ion Science PIDs
Introduction EPA Method 21 is the standard procedure for leak detection and fugitive emissions monitoring for VOCs. A continuously detecting meter is used to check joints and valves on pipelines and vessels, and if a significant leak is detected, repairs must be done. Any instrument can be used as long as it meets the specifications listed in Table 1. The Ion Science Tiger PID meets all these ...

An electromagnetic-based method for pinpointing leaks in buried pipes: a practical validation
In this paper, a time domain reflectometry (TDR)-based solution for detecting water leaks in underground pipes is described and experimentally validated. The proposed method strongly reduces the inspection time that is typically required by traditional leak detection methods. In fact, it can successfully inspect pipes that are hundreds of meters long. In this work, two different configurations ...

Leak detection by inverse transient analysis in an experimental PVC pipe system
Leakage reduction in water supply systems and distribution networks has been an increasingly important issue in the water industry since leaks and ruptures result in major physical and economic losses. Hydraulic transient solvers can be used in the system operational diagnosis, namely for leak detection purposes, due to their capability to describe the dynamic behaviour of the systems and to ...

F-Gas Regulations - An Update
How does the latest F-Gas Regulation affect refrigerant leak detection? January 2014 saw the revised EU Regulation of F-Gases following publication of a draft proposal by the European Commission at the end of 2012. The much anticipated regulation changes aim to strengthen the existing F-Gas Regulation and to ‘encourage’ the industry to move towards a HFC free market and use of low ...
