Overview
Built for modern gas utilities, the D‑GR1 smart diaphragm gas meter includes a signal pickup, communication module, and temperature/pressure sensors as standard - supporting remote reading, valve control, and real‑time fault detection. Compatible with both prepayment and postpayment models, it offers gas operators a flexible, future‑ready metering solution.
Available in G1.6, G2.5, and G4 sizes, the meter maintains accuracy through integrated temperature and pressure compensation. Housed in an IP65‑rated steel enclosure with a battery life of over 10 years, it supports NB‑IoT, 4G, LoRaWAN, and NFC for versatile connectivity - enabling tiered pricing, remote top‑up, and automatic alerts for abnormal operating conditions.
