Water Leak Detection with a Sensing cable

Water Leak Detection (WLD) uses a WLD sensing cable that detects liquid along the entire length of the sensing cable, which means it can monitor an extended area at once. Even the smallest amount of liquid (a few drops) can send the alert. Several WLD devices are available: WLD2, SD-WLD, NB-WLD, Sensor WLD Relay 1W-UNI.

Advantages of Water Leak Detection with sensing cable by HW group

• WLD sensing cable detects liquid along the entire length of the sensing cable

• Even the smallest volume of water, ethylene glycol, or other conductive liquid triggers the alarm

• Thanks to that you can react very quickly and avoid costly damages that could be the aftermath of flooding

• The cable has unique user-friendly features

  • No Bend limit: The sensing cable is not limited by any bending radius 

  • No Twist limit: The sensing cable can be twisted as any other electrical cable

  • No Grip limit: Water detection functionality is not limited by point pressure within a reasonable range.

Using WLD sensing cable

• Detects water across the extent area
• Detects the first few drops of water, reaction time is 1-5 minutes
• High installation costs

When using Water Leak Detection with a sensing cable you can detect the first drops anywhere in the monitored room/area. Thanks to the early alert significant damages to IT or other infrastructure can be avoided. Water Leak Detection with sensing cable is recommended in IT, data centers, technology, the medical sector, or anywhere else, where any water damage would be highly expensive. 

A sensing cable can be installed under raised floors in datacentres, wrapped along the pipes, routed along the walls, etc. Custom solutions for every need are possible.

Spot water Detection

Flood detectors monitor water presence at one predetermined spot. This means that the detectors aren´t able to detect small water leakage across the room if the water doesn´t cumulate directly around the detector. Flood detectors also have to be entirely flooded for the alarm to be sent out. HW group offers one sensor for flood detection Flood detector 1W-UNI. The advantage of using the Flood detector as a tool for Water Leak Detection is the low price. However, you risk costly damages to your property, hardware or inventory.

Using Flood detector

• Detects water in 1 point only
• Has to be entirely flooded, reaction time is long and the alarm is delayed
• Cost-effective installation and sensor

Unlike WLD, flood detectors detect water only in one spot and have to be entirely flooded. This means you will not be alerted immediately when a water pipe breaks but only after the area is considerably flooded. That is why it is not the ideal solution for data centers etc., where you need to be alerted before the water reaches your IT infrastructure. Only the WLD sensing cable ensures that.

The difference between WLD detection and Spot Detection

The main differences between WLD detection and Spot water detection are summered in the table below.

Both the WLD system and Flood detectors can be connected to HWg monitoring Eco-system with variable devices, for example with Poseidon2 as is shown in the following scheme.

Which product is suitable for your needs?

Each product is made for a different purpose. WLD sensing cable guarantees a quick response to any water present on your premises and is therefore most suitable for areas where water damage would be expensive. The applications are diverse, the sensing cable can be routed under raised floors or along the walls, wrapped along the pipes, or placed under air-conditioning outlets. On the other hand, a Flood detector can be used in places, where the water can´t do much damage and we don´t need to act quickly in case of a flood. Using a Flood detector in the data center equals receiving a swimming invitation among your racks and IT infrastructure, which is something you probably want to avoid.

A very detailed review of STE2 R2 by Csongor Varga. In this video, we are going to look at STE2 R2, how you can set it up and also what are the typical use cases for this device, and a lot more. (29:56 min.)

2. STE2 R2 & SensDesk: How to connect the STE2 R2 to the SensDesk portal - HV07

In order to come to this step, you need to have the device configured on your network. If you are using the ethernet connection this could be as simple as connecting an ethernet cable to the ethernet port of the device
If you want to use Wi-Fi,  you have to set up your Wi-Fi credentials. In this video, we are going to talk about how to connect STE2 R2 to the SensDesk portal. (1:25 min.)

3. STE2 R2 connectivity: How to connect the STE2 R2 to LAN via WiFi or WiFi + LAN - HV06

The STE2 R2 to supports 2 different ways to connect to the internet or your local network. In this video, we discuss how to connect the STE2 R2 web thermometer to LAN via WIFI or WIFI + LAN. (3:39 min.)

4. STE2 R2: How to send emails within the Gmail SMTP server from the STE2 R2 - HV05

This configuration is going to work exactly the same way with other HW group products and we are going to use the STE2 for this demonstration. (3:37 min.)

5. STE2 R2: Where to find technical details about this popular SNMP web thermometer? - HV08

When you are navigating around our website and studying various products the big icons on the product page usually show
you the key features of these products and these icons are shared so it makes it easy to compare the various products. And right in this video, we are going to show you where can find all the technical parameters and how to compare STE2 r2 with other devices. (4:52 min.)

6. STE2 R2 delay and hysteresis about remote temperature monitoring - HV09

STE2 R2 monitoring unit sends SMS, e-mail, and SNMP traps whenever a sensor value is outside of a safe range. However, when the temperature or humidity fluctuates, the unit can send tens or hundreds of messages that are unnecessary and bother the user. This video describes ways of avoiding false alarms. (5:17 min.)

7. STE2 R2- connection to SensDesk and HWg-cloud - HV12

In this video, we are going to talk about how to connect STE2 R2 to the SensDesk.com portal and free portal HWg-cloud. (2:11 min.)
