Water leakage and flooding can cause serious damage in homes, offices, technical rooms and industrial facilities. Even a small leak may lead to equipment failure, electrical risks, production downtime and costly repairs if it is not detected early.
The WATERSENS Water Flood Detector is designed to detect water leakage or flooding at an early stage and warn users before the problem becomes more serious. With battery or 24 VDC supply options, siren warning, alarm LEDs, relay output and different probe models, WATERSENS provides a practical and economical solution for water leakage monitoring and water level warning applications.
What Is WATERSENS?
WATERSENS is a water flood detector used to detect the presence of water in homes, offices and similar locations. It is especially useful in areas where water leakage or flooding may occur.
The device can be powered by a 9 V alkaline battery or 24 VDC. It has NO/NC contact output, allowing it to be connected to alarm panels or external control systems.
With its relay output, WATERSENS can also control a solenoid valve to help stop water leakage automatically. At the same time, the built-in siren alerts people nearby so that they can take action quickly.
Why Early Water Detection Matters
Water leakage is often difficult to notice in the first stage. It may start under a cabinet, near a pipe connection, around a machine or inside a technical room. If it is not detected quickly, the leak can spread and damage electrical equipment, flooring, walls, stored materials or machinery.
WATERSENS helps reduce this risk by detecting water at the beginning of a leakage or flooding event. The siren and alarm output allow operators, maintenance teams or users to respond before the damage increases.
Main Application Areas
WATERSENS can be used in many areas where water leakage or flooding risk exists. The catalog lists application areas such as operation rooms, computer rooms, storage areas, generator rooms, compressor rooms, air conditioning rooms, bathrooms, kitchens and all areas where water flooding may occur.
It can also be integrated with fire alarm systems or alarm panels when required.
For industrial facilities, WATERSENS is useful in technical rooms, utility areas, pump rooms, water treatment areas and automation rooms where early leakage detection is important for process safety.
Alarm and Warning Features
The standard WATERSENS unit includes 3 alarm LEDs and 1 siren with an On/Off button. These local warning elements allow users to identify alarm status directly from the device.
The siren attracts attention when water is detected. This is especially important in places where immediate human intervention is required.
The device can also be connected to an alarm panel, providing centralized monitoring in larger buildings or industrial facilities.
Sensor and Probe Connection
The standard sensor structure includes a two-core cable, with 1 meter standard length. Up to 3 sensors can be connected to the device.
The catalog diagram shows example installation with probes placed near the floor and connected to the WATERSENS unit on the wall using double-sided tape. This layout is practical for detecting water accumulation at ground level.
For cabled and terminal models, the catalog shows wiring details for input, relay and supply connections.
Power Supply and Battery Life
WATERSENS can operate with 1 x 9 V 6LR22 battery or 24 VDC supply.
Battery life is specified as 2 years in standby mode. This makes the device suitable for applications where wiring a power supply may be difficult or where a simple standalone solution is preferred.
Relay Output and Solenoid Valve Control
The device provides 2 A / 125 VAC NO/NC output. This relay output allows WATERSENS to be connected to alarm panels or to control external equipment.
One important application is solenoid valve control. When water leakage is detected, the relay output can trigger a solenoid valve to shut off the water supply. This helps stop the leakage source automatically and reduce damage.
Housing and Mechanical Features
The WATERSENS housing is made from ABS plastic. The standard color is black, with light gray available as an option.
The package includes 1 device, 1 battery, 1 double-sided tape and 2 wall mounting accessories. The device weight with package is 190 g, and the dimensions are 70 mm x 100 mm x 22 mm.
This compact structure makes WATERSENS easy to install in homes, offices, machine rooms and technical spaces.
WATERSENS-P / N / R Models
The WATERSENS-P / N / R versions are designed to detect water level in facilities and support preventive action. These models can be used to identify high water level or low water level conditions.
The electronics are located inside the housing and isolated with resin. This design helps protect the electronics from water influence.
The electrode material is stainless steel, and the electronic design is specially developed to prevent electrolysis at the terminals.
Technical Features of WATERSENS-P / N / R
WATERSENS-P / N / R operates with 18–29 VDC supply. The standard cable is 2 meters, available as 3 x 0.22 mm² or 5 x 0.22 mm² depending on output type.
