WFS International hydrological monitoring delivers real-time tracking of key parameters. Hydrological parameters: water level, flow velocity, discharge, and precipitation. Water quality indicators: pH, dissolved oxygen, COD, ammonia nitrogen, heavy metals, and more. Environmental data: water quality, air quality, and soil moisture to support ecological analysis. Main devices: water level meters, flow meters, rain gauges, and multi-parameter water quality sensors. Applications include flood control, with real-time water level and rainfall monitoring; water resource management, covering reservoirs for agricultural and urban water supply; pollution prevention, tracking industrial discharges and water quality anomalies; and urban waterlogging, monitoring water levels and reporting to traffic departments.
