Water flow detection came about in the late '70s when computer rooms were in their infancy. There are many leak detection companies that can help you in detecting leaks. For complete information about water leak detection, you can visit https://totalleakdetection.com/.
Computer rooms as now, comprise air conditioning that contains water to humidifiers and occasionally heated water for heating. Due to a lot of power cables, data cables, and water pipes needed from the room, a raised floor has been and is still used to hide all services.
Up to the mid-'80s water was discovered using place probe detectors. These components would consist of an etched PCB or two metal plates. Sensing for liquid was performed utilizing a DC voltage in one detector whilst searching for a return sign in another.
Supplying no recurrence signal was seen in the return sensor, no water was present. The issue using this type of system was the erosion of the detectors due to electrolytes and the limited region of water discovery, water could flow away from the sensors and not be discovered until too late.
During the mid-'80s water detection cable was developed. The advantage of the sort of sense being that water can be detected along the whole length of cable. This allowed areas or equipment containing water to be encompassed ensuring that leaks were found no matter what direction the water flowed.
