Sindcon Lorawan Water Meter

LoRaWAN Smart Water Meter

The Sindcon LoRaWAN Smart Water Meter Mercury LoRa series LXSGF model is an impeller (Turbine) water meter with a built-in valve and dry type register.  It is designed for residential applications with sizes ranging from Dn15 to Dn25, and is intended for metering cold drinking water.  The LXSGF model consists of a mechanical water meter, an electric ball valve, and an intelligent unit (IU) powered by ARM Cortext-M4 core integrated in LoRa SoC (System on Chip) and a built-in lithium battery. With the pre-equipped LorRa SoC, the analogue reading of the water meter can be digitalised and wirelessly transmitted to the meter data collection system.  Taking advantage of the LoRaWAN technology, it significantly accelerates the meter reading speed and avoids the risk of visual reading mistakes.  It also greatly improves meter readers’ safety and customer satisfaction by avoiding intrusion into private facilities.
