Aqualeak offer a range of different sensing techniques which will allow you to tailor your leak detection system to suit your application.

These include sensor cable, sensor probes and sensor pads. The type of sensing method used depends on the environment and requirement you have for leak detection. All the sensors work on the principle that water is a conductive element and can in effect close an open circuit. Sensor range and sensor accessories details
Water Leak Detection Valve Range

Solenoid valves are available for controlling the water flow to either switch off the supply in the event of a leak, or switch it on when demanded.

Valves are available in sizes between ½” and 2” and have zero lift specification and do not require any pressure differential for them to operate.  Water Leak Detection Valve Range Details
Autocall Telephone Dialling Unit

The AutoCall automatic dialing system can dial out to 10 different telephone numbers and plays a voice message to inform the recipient that there is an alarm.

There are four alarm inputs and a different message can be assigned for each channel. The Autocall will work with any of the Aqualeak alarm systems via a volt free contact.  Autocall Telephone Dialling Unit Details
SMS Alarm

The SMS alarm can be used to send text messages to up to five different phones when an alarm is triggered.

Up to four different devices can be connected to the alarm inputs and a bespoke message for each transmitted. It works with any mobile network SIM card and requires no fixed telephone line to operate making it ideal for working in remote locations. SMS Alarm Details
Beacon and Sounder

When positioned on the outside of a room or on the outside of a building the beacon/sounder can be used to alert that an alarm has been triggered.

It has a very load klaxon and a bright flashing light that would be difficult to ignore even from a considerable distance away. Beacon and Sounder Details
