Why choose Floodline?

Andel’s Floodline leak detection system, installed within critical areas of a building, provides a failsafe early warning system that allows for quick response to prevent damage, reduce disruption and limit loss. Andel's comprehensive range of sensors can detect water, commercially used gases and oil leaks as well as monitor temperature and humidity across multiple zones in any building.

Andel has over 25 years’ experience in the design, supply, commissioning and maintenance of leak detection and monitoring systems for all types of buildings including data centres, apartment blocks, office buildings, banks, museums and galleries, historic buildings, schools, hospitals and fuel storage facilities.


Floodline is a robust and reliable zone-based water, gas and oil leak detection and environmental monitoring system installed in sensitive and critical areas within buildings.

Saves time and money

Floodline systems allow early action to be taken to significantly limit the damage, disruption and loss that occur when leaks in buildings are allowed to go unchecked.

Unrivalled value for money

Floodline is cost-effective, easy to install and maintain, easy to use and totally dependable.

A range of sensors

Floodline offers a comprehensive range of water, gas and oil leak sensors, as well as temperature and humidity monitoring. Floodline gas leak sensors can be calibrated to detect the full range of commercially used gases including refrigerant gases, ammonia, methane, hydrogen, carbon monoxide, carbon dioxide and natural gas.

Multi-function control panel

Floodline leak detection sensors and monitoring equipment connect to a unique, single, multi-function control panel – more cost-effective to install, easy to maintain and monitor. Control panels connect to BMS via Modbus with a range of onward communications and output relays.

A zoned system

Floodline is unlike many other technologies, consistently delivering accurate warnings for multiple leak detection. It is highly resistant to false alarms that can be common with other technologies. All zones are electrically isolated from each other and If an alarm is activated, other zones remain unaffected, continuing to provide full leak detection monitoring. If a sensor or cable within a zone is accidentally damaged, the repair to the zone is simple and cost-effective, and importantly the system continues to provide full leak detection monitoring.

Long Line option

Floodline RANGER Long Line sensing cable and sub-panel provides even more choice to customers. RANGER can function as a zone in its own right, providing local meterage detection for longer areas up to 1500 metres and can be installed as a stand-alone system or connected to other Floodline control panels as part of a larger monitoring system.

Easily maintained

Choosing Floodline means that all electronic intelligence is contained within the single, hybrid multi-function control panel, which is always located above floor level and fully accessible. With some other systems, electronic intelligence can be located at numerous locations and often under floor level and difficult to access. Choosing Floodline significantly reduces disruption to core activities, saves money and avoids costly repairs.

Variable sensitivity

Floodline systems allow the sensitivity of each zone to be calibrated to take into account the environment and working conditions for that zone, significantly reducing the risk of false alarms.

Addressable system

Each zone can be equipped with any combination of leak detection and monitoring sensors.

BMS compatible

Floodline multi-function control panels allow alarm notifications to be relayed via single Modbus connection to BMS.

Future proof

Floodline systems allow additional zones, sensors and upgrades to be added easily and cost-effectively.
