Data Loggers
A wastewater network has points that matter a great deal and are rarely seen: manholes, overflow structures, and collectors. SOFREL data loggers measure flow and level at those sites, record events, and send the information over 2G, 4G, or LPWAN to your supervision system, with no cabling and no inspection rounds.
With them, network self-monitoring no longer depends on manual visits and reports. You know when and how often an overflow structure activates and can back it up with your own data, which is valuable for environmental management and for deciding where to invest. The devices also provide continuous diagnostics: they report their own status, so a fault is detected from the control center and not when someone arrives at the site.
Physico-chemical measurements add to the hydraulic data, helping you understand not only how much water flows through a point, but under what conditions. Everything is integrated into the same supervision system, compatible with SCADA and with the manufacturer's or third-party centralization software, so you can start at the most critical points and grow to cover the entire network.

View productA sewer network works almost entirely out of sight: under streets, in manholes and structures that are only visited when something fails or an inspection is due. Yet that is exactly where the most important information is: how much flow is passing, when an overflow structure is nearing its limit, and what happens to the water during heavy rain. SOFREL data loggers bring measurement to those points with compact, rugged devices designed for underground installations, flooding risk, and remote sites.
The device connects to the flow and level sensors at the site, records their signals at the interval you define, and transmits them over 2G or 4G, or over LPWAN when low power consumption is the priority. The data reaches your supervision system, where it is consolidated with the rest of the network and turned into alarms, reports, and trends.
That information underpins self-monitoring of the sewer system. With continuous records at overflow structures and key points, the utility knows when and how often discharges or overflows occur, and has its own evidence for environmental management and for prioritizing investment. Instead of reconstructing events afterward, it can see them as they happen.
A measurement point that fails silently is almost as problematic as one that does not exist. That is why the devices include continuous self-diagnostics: the data logger itself reports its status to the supervision system. Visits are then scheduled by real need rather than by calendar, which saves time at remote or hard-to-reach points and helps you trust that the data is still arriving.
Physico-chemical measurements add to the hydraulic data, helping you understand not only how much water flows through a point, but under what conditions. This combined view helps distinguish events, detect out-of-the-ordinary behavior, and support the analysis of discharges.
Integration does not mean starting from scratch. The range works with the manufacturer's supervision and centralization software and is compatible with other SCADA systems and with third-party applications used by water operators. Through open interfaces, the data can feed monitoring platforms, geographic information systems (GIS), and asset management systems (CMMS). These devices also complement Discharge Monitoring and Wastewater Treatment Monitoring within the Water Quality solution, by providing data from each point in the network.
The recommended path is to start with the most critical points and add others over time, until the measurement network becomes a permanent surveillance program for the sanitation system. If you are evaluating data loggers for your wastewater network, Marfel's team can help you define measurement points and the right communications architecture.
