2. Water detector - Wikipedia

   en.wikipedia.org/wiki/Water_detector

   Most modern leak detection systems developed around the use of a water sensitive cable [1] which can be laid in long lengths and complex patterns around the base of the floor; around the perimeter of rooms; as a "barrier" over which water has to flow; following, tracing or attached directly to lines of water pipes.

3. Leak detection - Wikipedia

   en.wikipedia.org/wiki/Leak_detection

   A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.

4. Hydrostatic test - Wikipedia

   en.wikipedia.org/wiki/Hydrostatic_test

   The test involves filling the vessel or pipe system with a liquid, usually water, which may be dyed to aid in visual leak detection, and pressurization of the vessel to the specified test pressure. Pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss.

5. Water metering - Wikipedia

   en.wikipedia.org/wiki/Water_metering

   These innovations aim to address challenges such as leak detection, water quality monitoring, and reverse flow detection. For instance, Pressure sensors are being tested to identify anomalies like pipe bursts or blockages, [37] Temperature sensors are evaluated for their ability to detect freezing risks or thermal variations in water supply ...

6. Pipe marking - Wikipedia

   en.wikipedia.org/wiki/Pipe_marking

   In the process industry, chemical industry, manufacturing industry, and other commercial and industrial contexts, pipe marking is used to identify the contents, properties and flow direction of fluids in piping. It is typically carried out by marking piping through labels and color codes. Pipe marking helps personnel and fire response teams ...

7. Double check valve - Wikipedia

   en.wikipedia.org/wiki/Double_check_valve

   A double check valve or double check assembly (DCA) is a backflow prevention device designed to protect water supplies from contamination. [1] It is different from the two-way check valves (sometimes erroneously referred to as double check valves) used in air brake systems on heavy trucks which select from the highest pressure source.
