Leakage detection using cable sensor and spot sensor
Introduction
Water or liquid damage caused by leaks can cause serious damage over time if not prevented in time and can cost businesses millions of dollars worth of damage. Water leaks are the most common reasons for data loss, equipment failure or facility damage. The loss of critical data can be devastating to a business, and no amount of money can bring it back once destroyed. By triggering an alert to be sent via e-mail or SMS text message to the personnel a company can have peace of mind knowing that equipment is safe.
System description
Vutlan offers a very powerful, and potentially money-saving water 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.
Vutlan water leakage detection system advantages include:
- The choice between "WLC / Water leak cable" & "Water leak sensor VT591" and "VT590 / spot sensor"
- Detectable liquids include clean, polluted, and distilled water; acids; alkalis; alcohols, and other electrically conductive liquids
- 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 ropes/cables is available and may be deployed on one floor or many levels of the building while being centrally monitored from the most effective locations.
- 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, 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 72 leak sensors independently of each other.
"VT591 / Water leak sensor", "WLC / Water leakage cable", "WDC / Water detection rope"
"VT591 / Water leak sensor" is an early warning system for large areas that alert the personnel or the operator at the operation center at the instant when a few drops of water appear. The whole area can be effectively monitored by placing the leaked cable or leak rope near or along with possible flood sources. VT591 can connect either "WLC / Water leakage cable" or "WDC / Water detection rope". The sensor reacts to just a few drops of liquid on the WDC rope or WLC cable. WDC can also detect the emergence of moisture. The cable is flexible and easy to install. VT591 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. Specifications are as follows.

WLC and WDC usage examples
Multiple spot liquid leakage detection
Vutlan water detection rope/cable can cover large areas and multiple spots for up to 225 meters. if there's an emergence of lipid anywhere along the rope, the system may send an early warning to the appropriate personnel.
Typical uses include:
- Below raised floors
- Along plumbing walls and under windows
- At drip trays and in overhead piping
- Under pipelines, sump pumps
- Under and around boilers, chillers, freezers and etc.
- Around potentially leaking equipment
Example: Leakage detection under raised floors
Raised floors, used sometimes in offices, server rooms, data centers are also particularly vulnerable. Monitoring the status of concealed cables and wires beneath floor panels may be difficult. Cables may be soaking in water for a long period before anyone notices.
Typical uses include:
- Below raised floors
- Along plumbing walls and under windows
- At drip trays and in overhead piping
- Under pipelines, sump pumps
- Under and around boilers, chillers, freezers and etc.
- Around potentially leaking equipment
VT590 / Spot water detector
When water is in contact with the metal cores, the sensor indicates the emergence of moisture. The sensor should be mounted in such a way that its metal cores should be pointing downwards as close as possible to the floor/surface where potential leakage may be. Full description, technical specifications, and manuals are available on the product page: VT590 / Spot water detector
VT590 / Spot water detector
Specifications:
| Size: | 60×18×18 mm | |
| Weight: | 125 g | |
| Inputs: | RJ-12 / RJ-11 | |
| Operating temperature: | Min. -10° C - Max. + 80° C | |
| Operating humidity: | Min. 5% - Max. 95% (Non-Condensing) | |
| Mounting: | Wall mount | |
| Max. distance from RMS: | 100 m | |
| Power Consumption: | 60 mW | |
| Cable length: | 2 m |
Example: Spot leakage detection
VT590 is used to detect pooling/dripping water and is best placed directly beneath equipment or in low-lying areas. For example, the most common reason for flooding server rooms is from leaking CRAC units. The best way to manage this is by deploying a spot water sensor underneath the drip pan of the CRAC unit.

Scalability
It is possible to connect up to 68 water leak sensors to a monitoring unit using "VT408 / Extension unit for analog sensors" on a CAN bus port.
VT591 preferences in the web interface
Inside the Vutlan web interface, You can change the sensor's name, behavior (normal or reverse); see the sensor's graph, or export its data in XML or CSV formats.
