Overview
Designed for residential and light commercial settings, this IP65‑rated ultrasonic gas meter measures flow rates from 0.016 to 6 m³/h, with dynamic correction for temperature and pressure fluctuations. Its fully electronic architecture has no moving parts, ensuring consistent accuracy and minimal service requirements over extended periods.
With built‑in IoT connectivity and an integrated safety shut‑off valve, the meter enables remote monitoring and automatic safety intervention. It supports GPRS, 4G, NB‑IoT, and LoRaWAN for adaptable network deployment. Housed in a rugged IP65‑rated steel enclosure and backed by a 12‑year operational life, it is an ideal choice for smart home systems and utility‑grade installations.
