Pulse meter ARF8428AAA

batchcycleIoT

Overview
This sensor is configurable on NB‑IoT and LTE‑Cat‑M1 networks and enables continuous counting and analysis of pulse outputs from water, electricity or heat meters and other equipment. It stores meter indexes periodically and transmits data to IoT platforms using MQTT(S) or LwM2M, and can also count equipment cycles to support maintenance planning. The wireless enclosure is designed for simple connection to meters and field equipment with pulse outputs.

Highlights

• Designed and manufactured in France
• Worldwide cellular compatibility (NB‑IoT, LTE‑M)
• Multi‑platform integration via LwM2M and MQTT(S) standards
• Up to 15 years autonomy with standard configuration
• 2 configurable pulse inputs to connect 1 or 2 meters or pulse‑output equipment (dry contact, REED, S0, open collector)
• Configuration via NFC
• Available in LoRaWAN and Sigfox versions

What actions does the PULSE sensor perform?
The PULSE sensor detects and records pulse‑based meter readings and operational events to enable consumption monitoring, anomaly detection and predictive maintenance.

Main use cases / functions

• Alert: detect leaks and anomalies in consumption
• Monitor: read back water, electricity and heat meter indexes and track excess consumption
• Count equipment cycles to schedule preventive maintenance
• Historization & buffering: batch transmission and local storage to protect data during outages

Services & packaging (summary)
Packaged offers include pre‑configuration of application parameters, SIM selection and installation, device provisioning on management platforms, fleet monitoring dashboards, training modules and access to technical documentation and installation/configuration apps.
