Data Logger Sofrel NEO DMA

The SOFREL NEO DMA (District Metering Area) is the IIoT data logger in the SOFREL NEO range dedicated to district metering of drinking water networks, leak detection and pressure measurement. 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 combines 2 digital inputs for meters or flowmeters, with standard or bidirectional metering, and 2 analogue inputs for pressure or level measurement with SOFREL CPR / CNPR sensors or third-party sensors powered through a 4-20 mA loop. From this data it computes the daily district metering balance (night flow, maximum flow, minimum flow and daily volume) and stores up to 100,000 data points locally. Data is transmitted 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 direct installation in valve chambers and underground pits subject to flooding, at the inlet of each district. It runs on an internal lithium battery with up to 5 years of autonomy, depending on configuration, and is configured on site via Bluetooth. Unlike the NEO LC model, the NEO DMA detects sensor faults and powers the connected pressure transmitters. 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 DMA can also communicate in M2M mode with SOFREL RTUs on DI status change or threshold exceedance, for remote site control.
