The Flow 7 was designed specifically for large complex residential applications in order to cater to the differing needs of such projects.

It can measure water volume in litres or timed usage, shutting off the water supply when a user specified volume/time is exceeded within a selected time period.

The Flow 7 has numerous settings and parameters to create a water leak prevention solution for any application. It will identify different flow levels using a pulse sensor sent to the control panel after every 1 or 10 litres of water flow, identifying leakage rates, e.g. continuous, high and/or low level, over set time periods with a self-learning audit function which monitors normal consumption.

The Flow 7 BREEAM WAT02 compliant water leak detection system reduces consumption of potable water through the effective management and monitoring of a buildings water consumption.

Multiple isolation valves can be added to protect against the damage and disruption caused by leaks. The controller is completely adaptable to suite the user’s requirements and water usage with several adjustable parameters and operational features.

Adjustable Parameters

The Flow 7 can analyse water usage by volume per ½ hour, hour, guard period or 24-hour period. The system has two separate menus for perimeter setting and day to day operation. The Guard Menu is used to input user specific requirements:

  • Maximum litre allowances in each 1/2 HOUR, HOUR, guard period or per 24 hours
  • Maximum override time to allow unlimited water. Override time can be scheduled in advance or initiated manually
  • Guard mode to suit buildings timetable. Or connect to the properties alarm for automatic guard level switching
  • Low guard times for when the building is occupied

Questions and Answers


Tony B, Sandhurst Plumbing

"The client was really happy with the whole process. We use Waterguard time and again for the quality and specifications of the systems. Yes, there are other systems on the market that will monitor water usage but not many with the added features that make it workable in an occupied environment.”


"Your staff are great, great service, thank you."
