Diagnosis of pipe systems by the SLE: first results

In this study, an algorithm is presented for pipe system diagnosis. The algorithm is the Successive Linear Estimator (SLE) previously used in groundwater hydrology to estimate the hydraulic proprieties of soils. The SLE is an iterative cokriging-like technique which provides statistically the best unbiased estimates and quantifies the associated uncertainty. In this paper the algorithm has been ...

Don’t Let Your Control System Control You

Regular maintenance ensures valves remain healthy. If your system is operating properly, you should physically inspect all valves at least every 12 weeks to check for tubing leaks and other abnormalities. Pressure gauges should be checked to ensure each valve is performing as designed. If you find something wrong, refer to the appropriate instruction manual, which may be available online. ...

Three separate water leaks located over a distance of 826m using the AQUASCAN TM2 - Case Study

Introduction Locating leaks on large diameter water mains can be very difficult due to poor sound propagation and increased distances between fittings that can be used to perform correlations from. For a correlator to highlight a potential leak each sensor must be able to receive the signal from that leak. Once a correlation is highlighted it is then down to the software and the user of the ...
