Upgrade Old Meters to Smart with HAC WR-G Pulse Reader | LoRa/NB-IoT Compatible

Short Description:

The HAC-WR-G is a robust and intelligent pulse reading module engineered for mechanical gas meter upgrades. It supports three communication protocols — NB-IoT, LoRaWAN, and LTE Cat.1 (selectable per unit) — enabling flexible, secure, and real-time remote monitoring of gas consumption for residential, commercial, and industrial environments.

With a rugged IP68 waterproof enclosure, long battery life, tamper alerts, and remote upgrade capabilities, HAC-WR-G is a high-performance solution for smart metering projects worldwide.

Compatible Gas Meter Brands

The HAC-WR-G is compatible with most gas meters equipped with pulse output, including:

ELSTER / Honeywell, Kromschröder, Pipersberg, ACTARIS, IKOM, METRIX, Apator, Schroder, Qwkrom, Daesung, and others.

Installation is fast and secure, with universal mounting options available.
