The water leak detection business is specialized and rather small with only a handful of manufacturers still functioning worldwide today. The original use has been on the ground floor created by "water room floors" in the old days of large central-frame computer networks. The "water room floor" is simply a sub floor with an access pipe leading to an upstairs floor or basement. In many older buildings, the water flow is through a single pipe with a downspout directed to a floor drain. Now, with most buildings now built with insulation and vapor barriers, these old water lines are no longer needed. This alone decreases their usefulness as a source for water leak detection. Newer technology involves the use of an acoustic probe combined with low-level radio waves. When water leaks occur they are detected with the probe causing an electronic signal to be sent up to a monitoring station. The signal is decoded by trained personnel and an audible alert is issued by the monitoring station. Discover more on what are the types of water detection systems on this website. There are other potential sources of water leaks but many companies have either moved away from them or are limiting their exposure to them. One such technology is through the use of low frequency acoustic beams which require extensive training and skill to install and use. Low frequency acoustic beams penetrate many objects including interior Styrofoam and concrete. Although the technology is new, it is being employed worldwide to treat water leaks in the utility and communications industry. These beams are also being used to detect water leaks in automobiles, particularly in the oil and gas sector. Other water leak detection systems are using the principle of piezoelectricity which involves the use of two liquids encapsulated in one membrane. This technology lies at the heart of most computer room leak detection systems. A small pump is then run on the liquid oxygen while a monitor continuously measures the amount of charge generated. If the charge generation level becomes too high, the liquids are moved to a different place for further analysis. This means that the same system can detect leaks in a variety of different liquids. The third type of water leak detection systems is digital and has been widely adopted by utilities and communication companies as the cheapest option. This is based on the principle that the leak can only be detected if the integrity of the system is compromised. For example, when computer rooms are designed the floors must be resistant to vibration which can easily damage computer equipment. In this way water leaks are detected before the damage is done. The final type of detection water leaks use a technology called the drip tray hydrospray alarm type detection system. The reason why this system is more expensive than all other methods is that it requires three individual probes that are placed on the pipe in question. The first two of these trays are placed around the pipe while the third tray is placed over a non-corrosive material like a piece of cloth. When the trays leak, the cloth will absorb the leak and signal the alarm be raised.
