A look back at the development of Water Leak detection in Computer & Server Rooms
Water leak detection came into being in the late 70's when computer rooms were within infancy. Computer rooms as today, contain air-con which contains water for humidifiers and sometimes chilled water for cooling. Due to the wide range of power cables, data cables and water pipes needed in the area, an elevated floor was and continues to be used to cover all services. Unfortunately, any water leaking under this raised floor would not be discovered until power/data leak detection connections were immersed in water and the computer stopped working.
Around the mid 80's water was detected using spot probe sensors. These units would consist of either an etched PCB or two metal electrodes. Sensing for water was done utilizing a DC voltage in one sensor whilst buying return signal in the other. Providing no return signal was observed in the return sensor, no water was present. The problem using this sort of system was erosion of the sensors as a result of electrolyses and the limited area of water detection, water could flow away from the sensors and not be detected until too late.
Throughout the mid 80's water detection cable was developed. The main advantage of this type of sensing being that water is detected along the whole amount of cable. This allowed areas or equipment containing water to be surrounded insuring that leaks were found no mater what direction the water flowed.
From the mid 80's through to today advances have mainly been with the alarm panels and the reporting of water leaks. Today you can be Texted, Emailed, receive a phone call, record it on a building management system or perhaps have the simple buzzer and lamp.
My involvement in water detection
I was asked to create a water detection system in the late 70's whilst working in terms of Vikingshaw Products Ltd. Our Mother company Vikingshaw Ltd during those times built computer rooms around the country and Vinkshaw Products supplied them with Power Distribution Units etc. The very first systems were simple in there design being DC based with PCBS for sensors and control units with an easy buzzer and lamp. Unfortunately it wasn't a long time before I found that DC wasn't the correct way to detect water as our sensor copper tracks would disappear if left in water for a few hours. It had been from this time that I used an AC signal in the sensors to avoid them eroding away. In the Early 80's I went into partnership and started an organization called Wayscale Ltd.
Throughout the 80's, 90's I developed a procedure to manufacture water detection cable and alarm systems to display water leaks from someone to 128 different areas or zones. The the top of range multi zone control unit used addressable outstations with 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 consent both my partner and myself decided to avoid trading and closed down the factory. Within the breakup of Wayscale, I took with me the merchandise design rights like the manufacture of the water detection cable and started CMR electrical Ltd with two of my sons. From 2003 to the present, developments have mainly been with the alarm controller as a result of improvements in electronics. During the past three decades I have already been responsible for the style of a large number of water detection systems which were installed atlanta divorce attorneys application imaginable from large government security buildings to small server rooms in the UK and abroad.
