4G LTE-M/NB-IoT IIoT data logger for wastewater quality monitoring, with 2 analogue 4-20 mA inputs, autonomous sampler control and IP68 watertightness

The SOFREL NEO WWQ (Quality Control) is the IIoT data logger in the SOFREL NEO range dedicated to wastewater quality monitoring in sewer networks. It is designed and manufactured by LACROIX Environment (LACROIX Sofrel), a French company specialised since 1971 in remote management and wireless data transmission for water and energy operators.
The device provides 2 analogue inputs and powers the connected sensors through a 4-20 mA loop at 12 V or 20 V. According to the manufacturer, it is intended for powering and controlling physico-chemical sensors such as conductivity, pH or redox potential, and for autonomous sampler control. It time-stamps every measurement, stores up to 100,000 data points and transmits them periodically, on schedule or on event to one or two SCADA central stations over 4G LTE-M / NB-IoT, with 2G fallback.
Its IP68 enclosure and waterproof connectors allow installation in manholes and underground chambers exposed to immersion. It runs on an internal lithium battery with up to 5 years of autonomy, depending on configuration, is configured on site via Bluetooth and detects sensor faults. It immediately reports threshold exceedances, enabling a prompt response to an abnormal discharge. The SOFREL NEO range received the Innovation Award in the instrumentation category at the H2O 2021 exhibition in Bologna, Italy.
Data is exploited in the SOFREL WEB LS cloud platform, in the SOFREL PCWin2 central station, or in third-party applications through web services and FTP, with analysis from a PC, tablet or smartphone. The NEO WWQ can also communicate in M2M mode with SOFREL RTUs on threshold exceedance, for remote site control.
