The ElecTo SJ is the single-jet meter that offers integrated data communication thanks to its innovative multi-protocol radio electronic register. This variant is designed for both indoor and outdoor residential applications and is available for cold and hot water. The LCD display simplifies data reading and makes additional information available to users and operators. Thanks to dual wM-Bus and LoRaWan communication, it offers maximum flexibility in short and long distance data communication and can be used with both mobile and fixed reading systems.
