A water detector is an electronic device designed to detect the presence of water and provide timely warnings to allow for water leakage prevention. The general design is a small cable or device that lies flat on the floor and relies on the electrical conductivity of water to reduce barriers in two contacts. The device then sounds a audible alarm along with signal forward with enough water to bridge the contacts. This is useful in areas normally occupied near potentially water-leaking infrastructure, such as HVAC, water pipes, drain pipes, vending machines, humidifiers, or water tanks.

Water leakage detection
Water leakage detection is a more common expression used for larger integrated systems installed in modern buildings or containing valuable artifacts, materials or other important assets where early notice of potentially destructive leaks would be beneficial. In particular, the detection of water leaks has become a necessity in data centers, trading floors, banks, archives and other critical infrastructure.
Water leak detection industry is small and specialized with only a few manufacturers operating worldwide. The original application was in a vacuum created by "computer room" flooring in the days of major computer systems-large frames. It uses modular, raised floors based on a structural "floor tile" typically 600 mm square and supported at an angle with a pole. The created void provides easy access and routing for the masses of power, networks and other interconnected cables associated with larger computer systems - processors, drives, routers, etc. Mainframe computers also generate large amounts of heat so that vacancies beneath the floor can also be used as plenary to distribute and spread cold air around the computer room. Therefore the void tends to have a cold water pipe that flows through it along with the condensate water channel associated with the cooling installation. In addition, the designer found the empty floor a very convenient place to route other wet service to eat bathroom, radiator and other facilities.
A leak that occurs inside the void floor will therefore escape the attention until the hydrostatic pressure head means that the water finds its way through to the floor below where it drips through the ceiling will be recorded or, and more confusingly, the water will penetrate the joints and power connectors or cable network and cause system failure of short circuit.
Current digital water leak detection systems can find several water leaks in 1 meter resolution through a complex cable network that runs several kilometers. This functionality reduces downtime and potential damage caused by inaccurate reporting that is common in older analog-based systems.
Water leak detection systems can be integrated with Building Management Systems using several protocols such as Modbus. Using the SNMP protocol, leak detection systems can inform IT staff responsible for monitoring data centers and server rooms. It is not only important to detect water leaks but also to be sufficient and immediately alert; if it does not take automatic corrective action.

Integrated multi-zone system
Therefore computer space becomes the initial application for a system that will alert operators to leaking pipes in sufficient time for corrective actions to be taken to prevent disaster.
Since computer space can be very simple, the "point of use" of the detector is not really precise although the Point Sensor has a value in which simple, single point detection is required in, say, basements and beds. Most modern leak detection systems are developed around the use of water-sensitive cables that can be laid in long and complex patterns around the floor floor; around the room; as a "barrier" in which water must flow; follow, trace or stick directly to the water pipe.
General apps
Most mainframe computer rooms have been replaced with Data Centers but fixed applications with almost universal use of "computer room" raised floors in almost all new commercial and office construction. To ensure the installation of leak detection, operators must understand the risks in addition to those circumstances, but most Electrical and Electrical Engineering Engineers will see the risk of damage from leaks in terms of affecting the operations, services, and services of the clients themselves. assets and, often equally important, from neighboring neighbors and those downstairs.
The installation of a leak detection system is therefore becoming more common in most new commercial office construction schemes along with clearer targets of museums, galleries and archives.
Leak detection systems should be unobtrusive, effective, and robust enough to withstand dirty and moderate physical abuse against other work undertaken under the same floor.
The zoned system has a secure, reliable reputation and is not vulnerable to the same type of false alarm that its systems use cumulative resistance techniques.
Manufacturers like TTK from France have introduced hi-tech variants such as FG-NET touch screen panels with interactive maps on the screen. The sensing cable is equipped with a patented micro-controller, allowing the unique ability to point-point errors on each individual sensory cable simultaneously.
The leak detection industry is very small and it can be expected that the manufacturer will also offer installation and after-sales service.
