IFAT Munich 2024

The world’s leading trade fair for water, sewage, waste and raw materials management

IFAT Munich will once again be the largest platform for water, sewage, waste and raw materials management in 2024. We will be there! Meet us on site from 13 to 17 May 2024 in Hall C1, booth 117 – we look forward to seeing you!

What to expect at IFAT 2024

  • Our water meters from large to small
  • The new IUWS ultrasonic water meter with parallel radio function
  • Exciting IoT solutions and use cases for the water industry
  • Our new complete digital solution Metering as a Service

ZENNER is celebrating 100 years of water meter production this year. The company has been producing its own water meters since 1924 – 100 years of innovation. This also includes the latest generation of the IUWS ultrasonic water meter, which offers the “parallel radio” function. This allows measurement data to be transmitted simultaneously via wM-Bus and LoRaWAN®.

ZENNER is also presenting the new digital complete solution “Metering as a Service”, consisting of meters, gateways and the LoRaWAN® network of ZENNER Connect. Wireless meters record the measurement data and can be read out via wM-Bus or LoRaWAN®. Both meter reading technologies are integrated into a single platform, the ZENNER Datahub, thus ensuring unrivalled meter reading rates. Metering as a Service fulfils all requirements for a future-proof and sustainable water supply. At the same time, this solution lays the foundation for variable water tariffs and supports customers in efficiently managing their water management processes.
