Fuji Electric's wireless data logger LOG V4 are essential tools for water network operators looking to improve their diagnostics and analysis. They provide rigorous monitoring of Electromagnetic flow meter M5000, take precise pipe pressure measurements (with a pressure transmitter powered by LOG V4), record them and transfer them to the central system. This valuable information makes it possible to detect network anomalies such as overpressure or insufficient pressure.
The irreplaceability of data loggers LOG V4 lies in their ability to provide detailed data analysis (daily volumes, maximum flows, night flows) over extended periods. This enables water system performance to be assessed. What's more, this high-precision data enables consumption balances to be drawn up, highlighting the areas most affected by leaks.
Challenges abound for operators seeking to maintain the integrity of wastewater distribution networks subject to environmental constraints such as erosion and ground movement. It is essential to protect water resources and minimize leakage, while meeting the demands of a growing population.
Against this backdrop, and in the face of major economic challenges, the aim is to achieve significant savings. This can be achieved by detecting and reducing leaks to limit unbilled water. The implementation of network sectorization, coupled with remote management, is an effective solution for water stakeholders.
Sectorization aims to quantify the treated water distributed to and from homogeneous sectors (500-3000 subscribers). Sectorization meters are connected to Fuji Electric's LOG V4 Autonomous Data Logger, which takes continuous readings at each network metering point. These autonomous recorders perform pre-calculations of flow rates (average, minimum, maximum) and draw up daily reports.
Operating 24 hours a day, Wireless Data Logger LOG V4 record night-time flow rates, essential information for identifying leakage areas. These data are transmitted daily to the central system for detailed analysis and cross-checking by sector. This makes it possible to quickly identify the emergence of a leak following a breakage.
The WIreless Data Logger LOG V4 features a threshold warning function, guaranteeing optimum reaction in the event of a leak. Using these predefined thresholds, it is possible to detect breakages upstream or downstream of a pipe. If a threshold is exceeded, an alert is automatically sent to the maintenance team's PC and cell phone.
Such data analysis, coupled with sectorization, gives operators the ability toeffectively direct detection campaigns towards priority sectors. The response speed provided by Fuji Electric's Data Loggers LOG V4 becomes a key factor in improving water network performance.
Thanks to the significant reduction in water losses, the investment in remote management equipment quickly pays for itself, demonstrating its essential role in water network management.
For any water distribution network operator, the task of regulation is a delicate one. Ensuring constant pressure throughout the network, providing a quality service to users and preserving infrastructures that can be weakened by the weather are complex missions to be carried out jointly.
Fuji Electric's Wireless Data Logger LOG V4 is an effective solution to these challenges.
With one or two analog inputs depending on the model, Fuji Electric offers continuous pressure measurement on water pipes. Compatible with all 4-20mA sensors on the market, the LOG V4 software powers and controls the sensor. It adapts its recording rate according to an alert threshold, enabling more detailed pressure analysis.
Fuji Electric also distinguishes itself by modulating pressure through intelligent management of a two-stage control valve. By lowering pressure during periods of low water demand, the LOG V4 reduces diffuse leaks, automatically limiting water losses.
