The Liberty Gas 220 is our next-generation smart gas meter, part of the time-tested and successful Liberty product family. This compact G4 residential meter uses micro-thermal mass flow measurement technology for accurate gas measurement, providing absolute energy readings in kWh and cubic meters. The meter supports remote communication with head-end systems via NB-IOT, enabling easy remote data collection, tariff upgrades and calorific value configurations. It operates in both credit and pay-as-you-go (PAYG) modes, with the flexibility to switch to either mode remotely during its operating life. Additionally, it offers optional short-range local wireless communication for commissioning and meter operations in areas where WAN connectivity is unavailable.
