Water metering
Data logger / Water metering
Effective monitoring of water level, water quality and currents
When measuring water, data loggers are indispensable tools for collecting real-time data on everything from groundwater levels and river flows to water quality and rainfall. They are often used in environmental monitoring, sewer systems, agriculture and construction, where accurate documentation of water-related parameters is essential. With data loggers, you can monitor changes over time and react quickly to deviations, supporting both sustainability and efficient resource management.
Data loggers for water quality and level monitoring ensure accurate measurements of:
- Water levels - monitor lakes, rivers and groundwater
- pH value - long-term monitoring of water quality
- Conductivity & salinity - monitoring saline water and runoff from roads and agriculture
- Temperature & oxygen content - ensuring healthy ecosystems. Our software makes it easy to read values remotely.
