AK-IWM LR4 Water meter


AK-GMDM Water meter can be used to measure liquid


IWM-LR4 has been designed to allow wireless remote reading in different types of applications in commercial and industrial sectors. The radio module thanks to the presence of the inductive target into the meter dial allows the reading of the volume consumption without any constraints of access to the site thanks to the Long Range LoRa radio technology and the compliance to the LoRaWAN standard can be intergated into multi-service networks.
