Hydropower

Monitoring the impact of Hydropower plant activities on water bodies can be important for regulatory compliance and modeling purposes.

Hydrolab instruments can measure total dissolved gas (TDG) levels around Hydropower activities and both Hydrolab and Sea-Bird Coastal instruments can be used to monitor temperature and dissolved oxygen upstream and downstream from plants to ensure regulatory levels are met and power production is optimal.

OTT sensors can be used to measure water level and flow of the reservoirs feeding the hydropower plants, as well as the in-flows and out-flows from the plant and sluice monitoring.
