Connect your meters to the IoT network with the ARF8428AAA, an IP68-rated pulse counter designed for water, electricity, and heat meters. This NB-IoT and LTE-Cat-M1 enabled sensor reads consumption data to help you monitor energy usage and plan equipment maintenance based on cycle counts.
The wireless sensor connects easily to any meter or equipment with pulse output—including dry contact, REED, S0 relay, or open collector types. It continuously counts pulses, stores meter readings, and transmits data via MQTT(S) or LwM2M protocols to your IoT platform.
Built and tested in France, this sensor offers worldwide cellular compatibility with up to 15 years of battery autonomy under standard configuration. Two configurable pulse inputs let you monitor multiple meters simultaneously, while NFC configuration keeps setup simple and field-friendly.
