Intelligent water management with smart measurement technology

Automatically read and monitor water meters so as detect system issues and leaks at an early stage. At ZENNER we offer a comprehensive solution for measurement technology and system solutions. Innovative M-Bus and radio solutions, the Internet of Things (IoT) and in particular LoRaWAN® technology offer a wide array of options.

The automated reading of shaft meters or leak detection, minimise water losses and gradually convert your water network into a smart water network. We are utilising precise measurement technology with software and network technologies to deliver a tailored solution for Water Industry 4.0.

Innovative technology for all measurement tasks

ZENNER offers a full range of water meters, allowing you to effortlessly complete all measurement tasks in drinking water supply and distribution. Our product portfolio ranges from single-jet meters, to various multi-jet and positive displacement meter versions, through to the full range of Woltman meters.

By combining precise measurement technology and innovative remote reading technology, you can transmit all consumption data with minimal effort in an accurate and secure manner. Our solutions are ideal for water consumption reading per apartment (submetering), applications in the drinking water supply and in the fields of waste water and agriculture.
