Siemens Industry Solutions Siwa LeakControl

September 2010 Vol. 65 No. 9

The new Siemens Siwa LeakControl location and monitoring system, not only continuously checks for leaks in water pipes, but also pinpoints them automatically.

The Siwa LeakControl is based on flow measurements and special software for evaluation. It can be used with all sizes and types of pipes, and helps to keep water losses as low as possible. This is done by setting up district metering areas, in which the inflows and outflows of water are measured by ultrasonic flow meters. Existing measuring systems, such as magnetic inductive flow meters, can also be integrated. The measurements are passed to an evaluation system, which detects leaks and allocates them to the individual zones by statistical methods and a model-based, network-wide mass balance. The suspected leaks are then found by temporarily installed acoustic sensors, and finally pinpointed down to the exact meter by correlators.
