Areas underneath the raised floors in data centers, IT rooms of other facilities are not visible and provide a hiding place for several threats to these critical spaces - conductive fluids, mold, rust, condensation, moisture, corrosion of equipment. Issues may not be identified until it becomes a much larger leak that wreaks havoc on the facility. The costs to repair them are then enormous. Having a water ingress detection system is therefore very important.

Causes

  • Dripping coolant from HVAC, CRAC, chillers
  • Seepage of the Water-Cooled Server Racks
  • A burst of a water pipe, drips, seeping clamp in your air conditioner system
  • Water from the soil or ground on the foundation of your site due to heavy rain or a thunderstorm.
  • Rare inspection of spaces and equipment due to short staff
  • Water pipe damaged by frost or a blocked sewage pipe, plumbing installations, water pipes, or water tanks
  • Unwarranted surge of water from a sprinkler system
  • Water Damage Through Vandalism as a Result of Burglary
  • Trickles from adjoining walls.

Leak detection system

Vutlan offers a very powerful, and potentially money-saving liquid leak detection system offering: leak detection cable sensors; water leak spot sensors; monitoring systems with built-in notifications (SNMP, E-mail, SMS, Syslog) for notifying the personnel; 12V control of alarm beacons and strobe lights; relay and dry contact outputs for control of devices

Detectable liquids:

  • clean, polluted and distilled water;
  • acids; alkalis; alcohols
  • other electrically conductive liquids

Advantages

  • Damage to the sensor does not cripple the entire monitoring system.
  • A robust web interface that gives the ability to independently track many leaks at once, with local, networked or remote alarms and diagnostics.
  • Different length of leak detection cables are available and may be deployed on one floor or many levels of the building while being centrally monitored from the most effective locations.
  • Pinpoint the location of the leak by using multiple sensors for each area.
  • Possibility to extend the WLC leakage cables by connecting them to each other.
  • Support of SNMP for integration to building management systems, E-mails, SMS, SNMP and Syslogs.
  • Configuration options that automatically shut off equipment or pumps/valves where appropriate (e.g. using dry contact outputs or relays).
  • Ability to monitor up to 208 leak sensors independently of each other.

Using VT591 & WLC cable sensor

The whole area can be effectively monitored by placing "WLC / Water leakage cable" near or along with possible flood sources. The sensor reacts to just a few drops of liquid on WDC rope or WLC cable. The cable is flexible and easy to install. "VT591 / Leak sensor" is an analog plug-and-play sensor, it is integration-friendly and quick to reset. After the flooding, the leak detection cable can be dried and reused. The sensor does not produce false alarm signals when bent or twisted. WLC can work in high humidity, pollution, and hazardous waste.

Scalability using VT408 & VT408DIN

Using CAN extensions it is possible to connect multiple sensors to the system using. VT960ii monitoring system can connect up to 208 leak sensors. VT335 monitoring system can connect up to 30 leak sensors.

Example: VT335 monitoring unit has x4 analog inputs for x4 leak sensors. But it is possible to connect x4 VT408 CAN extension units and provide connection for additional x26 leak sensors.

Vutlan monitoring units

Any Vutlan monitoring units can be used to monitoring VT591 leakage sensors.

Embedded Web Interface

All Vutlan monitoring units come with a built-in multi-language Web Interface for monitoring an control of the device. Here you can configure notifications & alerts, logic schemes, user access permissions, sensors and elements. You can also inspect sensor graphs, logs or view cameras.

Configuring Leakage notifications

  • Logic schemes are used for notification and equipment control.
  • Multiple leak sensors can be grouped for notifications.
  • If there's a leakage we can activate equipment (e.g. a light tower) or shut down the equipment.
  • Send alerts such as E-mails, SMS, SNMP Trap, record video, Dial a phone, or HTTP request.

Map panel

  • Leak sensors can be mapped on to a picture map depicting the floor map of the IT room.
  • Sensors highlighted in Green are in Normal state
  • Sensors highlighted in Red are in alarm state.
