Water Leak Detection Equipment

Look back at the development of detection of Water Leaks in the Computer & Server Room

Water leak detection appeared in the late 70s when the computer room was still a baby. The computer room as it is today, contains air conditioning that contains water for moisturizers and sometimes cold water for cooling. Because of the large number of electrical cables, data cables, and water pipes needed in the room, the raised floors are still used to hide all services. Unfortunately, the water leaking under the elevated floor will not be found until the power / data connection is dipped in water and the computer stops working.

Until the mid 80’s water was detected using a sensor probe. These units will consist of engraved PCBs or two metal electrodes. Sensing for water is done by using a DC voltage in one sensor while looking for a reverse signal in another. If there is no reverse signal visible on the back sensor, there is no water. The problem with using this type of system is sensor erosion due to electrolysis and limited detection of water, water can flow away from the sensor and not be detected until it’s too late.

During the mid 80’s water detection cables were developed. The advantage of this type of sensing is that water is detected along the cable. This allows the area or equipment containing water to be surrounded to ensure that no leak is found in what direction the water flows.

From the mid-80s to date progress has mainly occurred with alarm panels and water leak reporting. Today you can send SMS, Email, receive phone calls, record it on the building management system or just have a simple bell and lights.

My involvement in water detection

I was first asked to design a water detection system in the late 70s while working as a Vikingshaw Products Ltd. Our parent company Vikingshaw Ltd at that time built computer rooms throughout the country and Vinkshaw Products supplied them with Power Distribution Units etc. The first simple system there is a DC-based design with PCBS for sensors and control units with simple bells and lights. Unfortunately it wasn’t long before I discovered that DC is not the right way to detect water because our copper sensors will disappear if left in water for several hours. From this point I used the AC signal on the sensor to stop it eroding. In the early 80’s I formed a partnership and started a company called Wayscale Ltd.

During the 80s, 90s I developed a process to produce water detection cables and alarm systems to display water leaks from one to 128 different areas or zones. The top of the multi-zone range control unit uses a station that can be addressed with four independent water detection zones and a 24 numeric alpha screen to notify the location of water leaks in words and numbers. In 2003 and with mutual agreement, my partner and I decided to stop trading and closing factories. As part of the Wayscale split, I brought with me the product design rights including the manufacture of water detection cables and started CMR electrical Ltd with my two sons. From 2003 to the present, developments have largely occurred with alarm controllers due to improvements in electronics. Over the past three decades I have been responsible for the design of thousands of water detection systems that have been installed in every application that can be imagined from large government security buildings to small server rooms in the UK and abroad.

Considerations when designing a water detection system

A number of factors need to be taken into account when designing a water diction system. Failure to do so can cause the system not to detect water when asked to do so.

1) The use of alternating current (AC) instead of direct current (DC) in the sensor. Direct current will erode the sensor if left in water for a long time so the system cannot be used for the next alarm.

2) Adjustment of sensitivity to allow moist areas or condensed water from the AC unit to be ignored, but still allow large leaks to be detected.

3) Cross zone talks that lead to false alarms or wrong locations caused by a signal from one zone that uses Earth (floor jacks, channels, etc.) Interferes with other zones that cause one or both zones to enter the alarm without water.

4) Fast sensor recovery after water leakage. Detection cables and spot probes must be able to be removed and wiped with cloth or tissue paper to remove water which allows the zone to quickly reset.

5) Sensitivity of the sensor, electrodes that are too close to each other on both the water detection cable and the spot probe will cause false alarms due to condensation or water droplets.

Using alternating current stops electrolysis which causes the sensor to disintegrate and the system cannot detect water. The use of alternating current also allows the sensor to continuously monitor the water even when immersed in water. This allows the system to automatically set itself automatically once water has been released to the sensor without further action by the operator to return the system to normal operation.

Where does our system go

We have provided a system to look for water leaks in computer rooms, server rooms, plant rooms, UPS rooms, office shower rooms, office tea areas, vending machines, high-level metal beams in ice rinks, high-level water pipes, underfloor heating office pipe, waste overflow, water tank, wall space, drip tray inside and below the air conditioning unit and the bundle area for the tank. Our customers range from one of the largest online betting companies, one of the largest and most well-known centers of storage space in London, Jersey Telecom, various major office blocks in London and many small server rooms in the UK and Ireland.

Moving IT Equipment As Part of Your Office Move

On the one hand, moving IT equipment as part of office relocation is very easy.

You can usually just pull things out and insert the box or box in the carton and then into the vehicle. Of course, some things like server rack may be heavy but can usually be managed.

What can sometimes catch people who are not vigilant are things related to software and risk reduction. So, here are some key tips:

· Some IT equipment needs to be ‘parked’ by software or otherwise told it will be moved before you do it. He then takes steps to ensure that the components are made ready for a little physical shock. Make it clear whether this is needed for the equipment in question.

· Even though IT equipment, especially mobile ones such as laptops, theoretically does not depend on location, some do not. Some may have anti-theft devices in them that need to be handled before they are moved or they can detect your new location when turned on and immediately turn it off again.

· In related subjects, remember to notify your various service providers on the internet or the Cloud that you plan to move. Sometimes geographic changes can cause confusion for telecommunications software and services if the provider doesn’t know what’s happening.

· If a piece of IT kit is not specifically made for mobile devices, then moving it at a significant distance always causes caution. Specialist packaging is highly recommended and don’t be tempted by the “throw in the box” approach simply because you’ve heard that modern IT equipment is ‘strong’.

· In situations where your installation produces and uses fast internet and / or other volume telecommunications systems, it is possible that your communication provider will install special high-capacity equipment locally to deal with your load. It may not be visible to you. So, if you want the same service in your new location, check it out in advance rather than make assumptions or advance only with hope. If given enough notice, your provider must be able to make similar arrangements (if they don’t already exist) for your new location. But be careful, moving from a downtown or urban location to a rural or suburban area can sometimes cause difficulties in this case – so be prepared in advance.

· Although it’s usually not a problem lately, even so, consider the problem of electricity supply. Some locations may have a protected power supply and better power surges and others may not. Check to make sure your new location can accommodate loads and protect your equipment from nails and blackouts.

· Get ​​advice and guidance from people who support IT first. Make sure they are experts in office relocation and the specific types of technology you are moving, given that this is a myth rather than “IT Experts” will automatically know everything about each kit they meet. Some professional office transfer specialists may also advise.
