Sutron Iridiumlink logger 9602 type, 1308720 serial number
Water level sensors
OTT Radar Level sensor (RLS) 47421 type, 423438 serial number
OTT Pressure Level Sensor 47422 type, 450479 serial number
Yearly maintenance by NVE, short inspection by NP. Discharge measurements carried out on different water level/stages in order to convert from water stages to discharge/runoff.
Sampling water stage at hourly intervals using both radar sensor and pressure transducer during the summer season. Now water in the river during late autumn winter and spring.
TERRESTRIAL HYDROSPHERE>WATER QUALITY/WATER CHEMISTRY>WATER CHARACTERISTICS>WATER TEMPERATURE
Vemco Minilog-II-T the sensor are change every year.
Yearly exchange of logger by NVE. Data not online.
Water temperature measurements are made using a Vemco Minilog-II-T one sample each hour, during the summer season. Now water in the river during late autumn winter and spring.
