Leaks and flow

Detect leaks in your water supply

Detecting leaks early, helps you avoid damaging your building from leaking water and water waste, so you can find the leak in time to fix it, by non-intrusive methods like epoxy lining.

Alarms included

  • Leaks: The leak alarm works by monitoring wether the water consumption goes to zero at least once a day. We can detect leaks from about one drop per second, corresponding to four liter per day.
  • Missing flow: If it's difficult to identify any flow in the pipe, you will be warned. Alarms are still raised if they are detected. Missing flow can be due to a sensor installation failure, or because the temperature of the water in the pipe is close to the temperature of the surrounding air, which makes the alarm less sensitive.
  • Missing data: If there has been a data drop out (big enough to make the leak detection invalid) no (false) alarms will be generated, and you will be warned.

The alarms are calculated once a day, at 6 a.m. UTC time.

Alarms setup
Configurations: The included alarms are added automatically if you select the unit type "water pipe" when the unit is registered on ReCalc. No other configurations are needed.

Sensor installation
Sensors used: FlowMoniSpot

Installation: See installation instructions under FlowMoniSpot.


Note: Please remember that no surveillance is perfect in all cases: it means that in rare cases, the system might not identify a leak, and in in some rare cases, it will warn you even when no leak is present.

If a leak alarm is raised, but you doubt it's real:

Take a look and see if a toilet is running or a tap is dripping. If so, it might be you leak, and a good thing is to avoid spilling water, and enable monitoring of more harmful leaks.
Try to close the main valve, and see if the temperature reading off the pipe gets close to the temperature reading of the surrounding air.

If temperature reading of the pipe never reaches three degree Celsius of the reading of the surrounding air, your pipes are likely to have a leak.
