Observator Instruments offers a large range of hydrological sensors as well as complete integrated meteorological/hydrological measurement stations. The hydrological sensors are complemented with data loggers, telemetry and software for storing, processing and visualizing the measured data. For measuring in remote locations, we have solutions using solar power and telemetry using GPRS, VHF/UHF radio links or satellite communication.

Our hydrological sensors are often applied in lakes, rivers, channels, ditches, estuaries, swimming waters, coastal zones, harbors and in ground water. Our customers are mainly related to the dredging sector, fishing and fish farms, municipalities, drinking water supply, environmental organisations, shipping, offshore industry etc.
