Legionella is a genus of bacteria commonly found in natural water sources such as rivers and lakes. However, when these bacteria enter man-made water systems, such as plumbing and cooling towers, they can multiply rapidly under favorable conditions. The most concerning species, Legionella pneumophila, can cause Legionnaires’ disease - a severe form of pneumonia - and Pontiac fever, a milder illness. This makes controlling Legionella in water systems essential, particularly in buildings such as hospitals, hotels, and residential complexes.
Traditional Legionella Monitoring is Expensive
Preventing Legionella bacteria growth has traditionally relied on manual checks and analog monitoring. Staff routinely inspect water systems to ensure water is flowing and maintained at safe temperatures. This often involves:
- Listening to pipes to confirm flow
- Flushing unused taps and showers to avoid stagnation
- Using thermometers to check that hot water stays above 50°C and cold water below 20°C
- Recording temperature readings and actions in logbooks for compliance
- Collecting water samples for occasional lab testing to detect bacteria
While this approach can be effective, it is time-consuming, depends heavily on human accuracy, and provides no real-time insight into potential risks.
Water Grip - An Advanced Defense Against Legionella
The Water Grip is an innovative, non-invasive water meter designed to provide comprehensive monitoring of water systems, playing a vital role in Legionella prevention. Its ultrasonic technology offers high-accuracy flow and temperature readings while requiring no plumbing expertise for installation.
Here’s how the Water Grip safeguards your property:
Temperature Monitoring
Legionella thrives in water between 20°C and 50°C, but with Water Grip, you stay one step ahead. It continuously monitors water temperature from 0.1°C to 70°C with outstanding ±2% accuracy, helping you spot conditions that could support bacterial growth.
Catch potential risk zones early. The Water Grip empowers property managers to act fast, to stop bacterial growth before it starts.
Prevent Stagnation
Still water can be a hidden risk, it’s the perfect breeding ground for Legionella.
With Water Grip, you get accurate detection of water flow and instant insights into whether flushing has taken place, helping you stay safe and compliant
Data Insights, Wirelessly
Through the Quandify portal and app, property owners can remotely monitor water flow, temperature, and system integrity.
With API:s, the possibility to integrate are endless.
Remote Temperature Readings
Follow your water temperature to establish wether the water is within safe temperature spans, or if heating is required.
Hourly datapoints are available on the Quandify Portal.


Wondering how long the water has been still?
See if your water has been stagnant for some time, down to an hourly basis.
Flush pipes only where and when necessary - no more redundant work.
The volume data is available both through the smartphone app and on the Quandify Portal.
