Buckley Water Leak Detection Equipment

A peek back at Water Leak Detection in Device & Server Rooms

Detection of water leakage happened in the late 70’s as data rooms were in existence there. Computer rooms, as they are today, are fitted with air conditioning and contains water for humidifiers and often chilled cooling water. Due to the large amount of power cables, data cables and water pipes needed in the room, a raised floor was used to hide all services, and is still used. Sadly, the water contamination will not be detected beneath this elevated floor until power / data interfaces were submerged in water and the machine started running.

Water was observed with spot probe sensors before the mid-80’s. Such devices will either consist of an engraved PCB, or two metal electrodes. Water sensing was done using a DC voltage in one sensor while seeking a return signal in another. The return sensor produced no return signal was detected, no water was found. The issue with this form of device was sensor loss due to electrolyses and the small region of detection of water , water could move away from the sensors and not be identified until too late.

Water detection cable developed in the mid 80’s. It method of sensing has the benefit that water is sensed over the entire length of the cable. It required nearby areas or facilities holding water to insure that no matter what way the water circulated, leaks were detected.

Since the mid-eighties to now, developments have been mostly for warning panels and water leak coverage. You may obtain a phone call, document it on a building control device today, or even have the basic buzzer and light.

Considerations regarding design of a water detection system

When constructing a water dictionary program a range of considerations must be taken into consideration. Failure to do so may result in systems not being able to detect water when required.

1) The usage of alternating current ( AC) in sensors which is not direct current (DC). If kept in water for long periods, the Strong Current can erode the sensors making the device unusable for any future alarms.

2) Sensitivity modification to make it easier to disregard the moist areas or accumulated water from AC systems, but also to spot major leaks.

3) Area cross-discussion contributing to false alarms or inaccurate location triggered by one signal from one region utilizing Earth (floor jacks, ducts, etc.) to interact with another area allowing either or all zones to go into warning without any water present.

4) Regeneration of a fast sensor after water leak. Detection cables and spot samples should be able to be extracted and cleaned with a cloth or tissue paper to remove water which helps the zone to reset quickly.

5) Sensitivity of the sensors, electrodes too close to one another in both the water detection cable and the spot probes may trigger false alarms due to condensation or water droplets.

The use of an alternating current stops electrolysis which causes the sensors to disintegrate and prevents the system from detecting water. The usage of alternating current often allows the sensors to track for water constantly, including while immersed in mud. This allows the system to automatically reset itself quickly once water has been removed by an operator for the sensor without further action to reset the system back to normal operation.
