This is a new type of smart water meter that uses a Rotary Type Water Meter as its base.
Internal structure: Equipped with an integrated communication module and SIM card. 4G network enables direct transmission of water meter-collected data (flow rate, temperature, signal strength) to the meter reading system, achieving data collection, remote control, and fault alarm.
External structure(A split design): the electronic unit is installed in an independent fully sealed cavity, with a waterproof performance of IP68 rating. It maintains the structure and accuracy of traditional wet-type water meters.
