We will be there! On May 21 and 22, 2025, the Gas Water Congress and Trade Fair will take place in Graz – the central platform for innovations and future topics in gas and water supply.
The focus will be on practical solutions, current challenges and an open exchange with experts from network operation, supply, industry and planning. At the accompanying trade fair, we will be presenting our latest products and digital technologies for water supply – from classic water meters to smart IoT and LoRaWAN® solutions.
- Remote meter reading with Metering as a Service
- Our water meter portfolio, such as the new IUWS ultrasonic water meter with parallel radio function
- Exciting IoT solutions and use cases relating to the water industry
We look forward to your visit and exciting discussions!
The first step towards digital water management
Water meters from ZENNER
With water meters from ZENNER, you can intelligently solve all tasks in drinking water supply and distribution. A real innovation is the latest generation of the IUWS ultrasonic water meter, which offers the ‘parallel radio’ function. Measurement data can be transmitted simultaneously via wM-Bus and LoRaWAN®. This guarantees the most seamless metering possible.
Metering as a service
Discover the complete solution Metering as a Service, consisting of meters, gateways, data solutions and our LoRaWAN® network. Wireless meters record the measurement data and can be read out via wM-Bus or LoRaWAN®. Both reading technologies are integrated into a single platform, the ZENNER Datahub, thus ensuring optimum reading rates.
IoT solutions for the water industry
The Internet of Things has become a driver of digitalisation in municipal utilities, local authorities and the municipal cross-sector network and offers technologies that are easy to install and can be scaled as required – without great effort or high economic risks.
With innovative solutions in the areas of smart metering, water management, flood protection and smart city, we are demonstrating that we play a key role in the digital transformation of cities and municipalities.

Monitoring of water levels
With LoRaWAN® you can monitor water levels in real time.
Monitoring the water quality
With IoT from ZENNER, you can monitor water quality consistently and reliably.
Smart leakage detection
With this solution, water damage caused by burst pipes or leaks is a thing of the past!
