ACRIOS Systems: Meter interfaces for LoRaWAN and cellular collection

ACRIOS Systems makes meter interfaces that carry selected Modbus, M-Bus and pulse readings into LoRaWAN or NB-IoT networks.

Summary

Best for
Reusing installed meters while adding a suitable wireless collection path.
Less suited to
Assuming a converter creates a measurement absent from its source meter or guarantees a reporting interval independent of power and radio conditions.
Deployment
A converter at the meter, using the selected LoRaWAN or cellular variant and receiving system.
Data in
Product-specific wired M-Bus, wireless M-Bus, RS485 Modbus or pulse inputs; network outputs depend on the converter.

Overview

ACRIOS Systems makes converters for remote meter reading. Its catalogue is organised by the interface already available at the meter, including wired M-Bus, wireless M-Bus, RS485 Modbus and pulse outputs, and by the LoRaWAN or NB-IoT network used to deliver the data. Wireless M-Bus to NB-IoT and wired M-Bus to LoRaWAN are highlighted product combinations.

This is a retrofit-focused offering for installed water, gas and heat meters. The company page also describes custom hardware, firmware and integration work. That combination supports both repeatable meter-reading deployments and projects requiring a specific interface or configuration beyond a standard catalogue unit.

Offering

The Modbus RS485 to NB-IoT converter supports battery or external power and includes an auxiliary supply for connected sensors. Its enclosure is rated IP67, with an SMA antenna connection that allows an antenna to be positioned outside a metal cabinet. A Lua scripting interface configures the reads for the connected equipment.

The S0 pulse-input NB-IoT product targets gas metering, including a named ATEX Zone 2 variant. It has a local display and stores readings for later delivery. ACRIOS also describes a non-ATEX version for water and industrial metering, making the installation environment an explicit choice within this product offering.

Products and platforms

  1. ACR-EX pulse-input device

    Single S0 pulse-input device with a counter display and NB-IoT Release 14 connection; primarily described for gas metering.3

  2. Wired M-Bus to LoRaWAN converter

    Collects wired M-Bus meter data and sends it over LoRaWAN.6

  3. Wireless M-Bus to NB-IoT converter

    Collects wireless M-Bus meter transmissions and forwards data over NB-IoT.6

  4. Modbus RS485 to LoRaWAN converter

    Interfaces compatible RS485 Modbus meters with LoRaWAN.6

  5. Pulse Input S0 to LoRaWAN converter

    Counts S0 pulses and transfers readings over LoRaWAN.6

  6. Wired M-Bus to NB-IoT converter

    Collects wired M-Bus meter data and transfers it over NB-IoT.6

Technology

ACRIOS's Modbus converter uses project-specific configuration rather than claiming universal register discovery. The company describes configuring the Lua script around the connected meter or sensor. That is useful where a serial pressure sensor or heat meter needs a cellular collection path with the appropriate reads already prepared.

Its open-interface article discusses MQTT, HTTP and APIs as ways to make collected data available to other applications. The company page also describes OMS participation alongside support for proprietary meter protocols. These are separate stages of the collection path; a tested Edge integration remains unverified in this research.

Customers

In its October 2025 deployment account, ACRIOS describes commissioning 10,000 wireless M-Bus concentrators connecting 850,000 meters over ten months. The account focuses on an existing mixed meter estate, with concentrators forwarding local readings through NB-IoT. It describes validating real meter samples before rollout and increasing concentrator density where measured collection performance required it.

The same account explains the operational preparation: configured devices, active SIM cards, production metadata and reporting on silent meters and read success. These details make the example useful for understanding ACRIOS's role in a deployment. It is a manufacturer-reported project, rather than an independently audited performance result.

Company

ACRIOS Systems s.r.o. publishes its office and delivery address in Rožnov pod Radhoštěm, Czech Republic. The Czech business register records the company's incorporation on 16 May 2016. ACRIOS separately dates its LoRaWAN and NB-IoT converter development to 2017.

The company page identifies Radim Malinowski as CEO and Marek Novák as CTO, and says development and manufacturing take place within the European Union. It describes deployments across several European countries and beyond Europe. Standard converters sit alongside a custom-development service covering hardware, firmware and integration, reflecting the company's engineering focus on remote collection from an existing meter estate.
