Meet us at Metering Days 2025 in Fulda
On October 28 and 29, 2025, the energy and utilities industry will once again gather at Metering Days in Fulda, the leading trade fair for smart metering systems, digitalization, and IoT in the energy and water industry.
ZENNER will also be there as an exhibitor, presenting practical solutions that enable utilities, network operators, and municipalities to make their metering infrastructure resilient, secure, and future-proof.
We look forward to seeing you there!
The first step toward digital water management
We have been manufacturing water meters for over a century and are constantly driving forward the development of innovative measurement technology. Today, as a smart water solution provider, we offer a portfolio of solutions that enable water utilities to digitize numerous processes in water management, from digital meter reading and water quality monitoring to flood protection.
The IUWS ultrasonic domestic water meter
The IUWS ultrasonic domestic water meter is the perfect way to get started with digital measurement data collection. Thanks to the innovative “parallel radio” function, measured values are transmitted simultaneously via LoRaWAN® and Wireless M-Bus – for reliable data collection even in difficult network conditions.
Metering as a Service (MaaS) by ZENNER
The complete solution for economical and scalable remote reading of water meters. In addition to pure meter reading, MaaS enables additional applications such as pipe network monitoring, water level measurement, or monitoring of pumping stations—without the need for your own infrastructure.
Resilient infrastructures
Whether smart submetering, smart buildings, or smart cities: with LoRaWAN®, you can quickly and easily take your projects to the next digital level. This saves effort, reduces costs, and opens up new possibilities, for example for the smart control of buildings, neighborhoods, or entire cities. Our LoRaWAN® network is now the largest of its kind in the world and continues to grow.
Connection shapes the future
