Reading Sensus meters with zero hardware changes

Sensus (Xylem) meters are well-proven. But integration is another story. Sensus meters, now part of the Xylem group, are no strangers to water distribution networks. They’re robust, reliable, and can be found in nearly every second utility system. But one recurring challenge is their integration into a unified data infrastructure. As soon as remote reading or automated data collection enters the conversation, questions arise: what protocol is being used and can it actually be connected easily?

Two protocols, two challenges: wM-Bus and Bubble UP

Most utilities today deal with a mix of two communication protocols. One is the open wM-Bus standard, often in a version compatible with the OMS specification. These devices can be connected via standard concentrators or LoRaWAN networks – a common and popular setup. The second option is less flexible: a proprietary protocol known as Bubble UP, or FlexNet. It uses a closed communication model, which becomes a challenge when trying to unify data from different meters in one place.

How ACRIOS handles integration, without touching the meters

When a utility owns a mix of both meter types, which is very common, the key question becomes: is it even possible to bring them all into one system without hardware replacement or complex work arounds? That’s where ACRIOS technology steps in.

We offer a solution designed to handle both protocols simultaneously without deep configuration and without accessing the meters directly. For open wM-Bus devices, integration is straightforward, via LoRaWAN or standard concentrators. Where meters use Bubble UP, ACRIOS converters are deployed to collect data externally, without interfering with the device itself. No need to open anything, reprogram firmware, or depend on the original manufacturer. Data simply arrives and your system can work with it like any other input.

One system, no matter how old or new your meters are

The real benefit of this approach is continuity. There’s no need to decide what to replace and what to keep. Everything already in the field can be integrated into one clean platform. Whether you're dealing with decade-old meters or newly installed digital units. On the data layer, the outcome is the same: automatic, transparent, and hands-free reading.

Digitalisation that respects your infrastructure

For operations management, this means fewer complaints, faster fault diagnostics, fewer truck rolls, and better consumption forecasts. It also lightens the load on your team. No need to juggle multiple systems or manually merge exported data. Water utility digitalisation isn’t just about “smart meters”. It’s about how simply things connect. We at ACRIOS build on openness, easy integration, and respect for what’s already working in the field. That’s why it offers a solution that doesn’t disrupt infrastructure but expands and connects it logically.
