Overview
Designed for homes and light commercial use, this G2.5 Ultrasonic Gas Meter covers a flow range of 0.016–6 m³/h and offers a service life of 12 years or more. Real-time temperature and pressure compensation help maintain accuracy as operating conditions change, while the all-electronic, no-moving-parts design keeps precision stable with minimal maintenance.
Built-in IoT connectivity and a safety shut-off valve support remote monitoring and automatic safety responses. Communication options include GPRS, 4G, NB-IoT, and LoRaWAN. With its rugged IP65 steel housing, it suits both smart-home and utility installations.
