See ACR-EX data live
Want to see how the ACR-EX datalogger works in the field? See a live unit on Datacake platform. Explore a real-time dashboard with actual data, including signal strength, consumption graphs, transmission logs. What you see is exactly what you'd get from your own deployment.
Datacake offers a ready-made template for the ACR-EX, setup takes just minutes.
How to get started
For initial testing, we can provide a device with a SIM card and integrate into a partner system. No setup effort required on your side.
We offer OEM units with an open communication protocols to be integrated directly into your services with no added API licensing fees.
We ship fully prepared devices, tailored to your setup. Including your SIM card, your configuration, and installation material if needed.
Trusted by leading gas distributors
With ACRIOS ACR-EX devices, we can retrofit our existing gas meters and ensure compliance with EU requirements. The installation was simple, the system is reliable, and our teams save time and resources.
Future-proof your gas metering with ACR-EX
Reduce operational costs, meet EU compliance, and ensure safe remote reading in ATEX environments. Retrofit your existing gas meters today with ACR-EX.
Frequently asked question
Yes, if they use an S0 or Wiegand output. You can send us the meter type with datasheet and we’ll verify compatibility.
No. On the contrary – ACR-EX is designed to connect to existing meters without replacement.
Yes, device is certified for ATEX zone 2 (depending on the variant). The device meets safety standards and offers IP67 protection.
Device is mounted on a wall, pipe, or bracket (using a strap or screws), connected to the pulse output, and powered on. We can deliver it preconfigured, including network settings and inserted SIM card you provide us with – setup takes around 10 minutes.
Device is configured locally by using an optical head with IEC 62056-21 protocol (compatible with standard technician tools) or remotely via NB-IoT (downlink/OTA).
By default, readings are taken hourly and sent once per day. Intervals can be adjusted as needed.
More than 10 years in standard mode with hourly readings. Battery is monitored using a coulomb counter providing an actual measurement, not an estimate.
Yes, the LCD screen shows the current counter value, so technicians or anyone else can check it directly on-site.
We support open protocols (UDP), standardised data formats, and direct transfer to SCADA/AMI systems. No intermediary platform needed.
Yes. We’re happy to send 1–2 units for pilot testing. We’ll help with configuration and onboarding.
Yes, as long as the meter provides a standard S0 or Wiegand signal. We support a wide range of voltages, frequencies, and output types. If unsure, send us the meter type with the datasheet and we’ll confirm compatibility.
The device stores readings internally for up to 40 days. Once the connection is restored, data is sent automatically. It also includes reconnection and network outage detection mechanisms.
Yes. We already support secure transmissions (DTLS), remote updates (FUOTA), and we’re actively developing full CRA compliance in partnership with Czech universities. Critical infrastructure clients are notified in advance.
We manufacture hardware, not data services and so we won't limit you with your deployment. You can use your own SIM card and transfer data directly to your backend – via UDP, including closed APNs or VPN tunnels.
Yes, we can help ensure future compatibility by following open standards, versioning, and modular architecture.
