A see forward at the go serve on of Water Leak detection in Computer & Server Rooms
Water leak detection came more or less in the tardy 70's once computer rooms were in there infancy. Computer rooms as today, contain heavens conditioning which contains water for humidifiers and sometimes chilled water for cooling. Because of the large amount of knack cables, data cables and water pipes needed in the room, a raised floor was and is still used to conceal all facilities. Unfortunately, any water leaking below this raised floor would not be discovered until carrying out/data familial were immersed in water and the computer stopped in doings.
Up to the mid 80's water was detected using spot investigate sensors. These units would consist of either an etched PCB or two metal electrodes. Sensing for water was curtains using a DC voltage in one sensor whilst looking for a compensation signal in the added. Providing no recompense signal was seen in the compensation sensor, no water was faculty. The terror using this type of system was erosion of the sensors due to electrolyses and the limited place of water detection, water could flow away from the sensors and not be detected until too tardy.
During the mid 80's water detection cable was developed. The advantage of this type of sensing physical that water is detected along every portion of length of cable. This allowed areas or equipment containing water to be surrounded insuring that leaks were found no mater what government the water flowed.
From the mid 80's through to today advances have mainly been later than the alarm panels and the reporting of water leaks.

My involvement in water detection
I was first asked to design a water detection system in the late 70's whilst vigorous as for Vikingshaw Products Ltd. Our Mother company Vikingshaw Ltd at that grow old-fashioned built computer rooms as regards the country and Vinkshaw Products supplied them considering than Power Distribution Units etc. The first systems were easy in there design bodily DC based when PCBS for sensors and aspiration units subsequent to a all along radio alarm and lamp. Unfortunately it wasn't long in the in the in the past I discovered that DC was not the fiddle once way to detect water as our sensor copper tracks would disappear if left in water for a few hours. It was from this mitigation that I used an AC signal in the sensors to halt them eroding away. In the Early 80's I went into partnership and started a company called Wayscale Ltd.
During the 80's, 90's I developed a process to fabricate water detection cable and alarm systems to display water leaks from one to 128 rotate areas or zones. The extremity of the range multi zone run unit used addressable outstations subsequent to four independent water detection zones and a 24 alpha numeric display to advise of the water leak location in words and numbers. In 2003 and by mutual comply both my connect and myself approved to halt trading and closed the length of the factory. As share of the breakup of Wayscale, I took subsequently than me the product design rights including the fabricate of the water detection cable and started CMR electrical Ltd subsequent to two of my sons. From 2003 to the sustain, developments have mainly been subsequent to the alarm controller due to the improvements in electronics. During the appendix three decades I have been answerable for the design of thousands of water detection systems which have been installed in all application imaginable from large position security buildings through to small server rooms in the UK and abroad.
Considerations once designing a water detection system
A number of factors compulsion to be taken into account taking into consideration designing a water diction system. Failure to reach therefore could lead to systems not detecting water past required to undertaking hence.
1) The uses of an swap current (AC) not focus on current (DC) in the sensors. Direct Current will erode the sensors if left in water for long periods leaving the system unusable for any subsequent alarms.
2) Sensitivity getting used to to song damp areas or shortened water from AC units to be ignored, but nevertheless make a clean breast large leaks to be detected.
3) Zone mad chat leading to faithless alarms or incorrect location caused by one signal from one zone using Earth (floor jacks, conduit etc.) to interfere plus calculation zone causing one or both zones to go into alarm without the presents of any water.
4) Quick sensor recovery after a water leak. Detection cables and spot probes should be glowing of being removed and wiped subsequent to a cloth or tissue paper to remove water allowing the zone to speedily reset.
5) Sensitivity of the sensors, electrodes too stuffy to each added in both water detection cable and spot probes will cause faithless alarms due to synopsis or water droplets.
Using an every second current stops electrolyses which causes the sensors to disintegrate and the system unable to detect water. The use of out of the shadowy current also allows the sensors to all the time monitor for water even in the middle of submersed in water. This allows the system to speedily automatically self reset gone water has been removed for the sensor also no subsidiary undertaking by an operator to reinstate the system to the lead going on to customary operation.
