SEBA Mini current meter type M1 + SEBA Signal Counter Z6; quantifying the discharge of surface flow with laminar flow conditions (flow velocities 0,03 – 5 m/s) SEBA Mini current meter
Q-Trace (discharge measurement method by salt dilution method) This measuring method is used in high gradient channels. At such locations it is impossible to perform measurements with the current meter because of the high turbulent flow. Q-Trace
WTW – measuring tools (water temperature, electric conductivity of the water, pH-value of the water; field chemistry) WTW measuring tools
Electric contact meters (up to 250 m)
Measuring the water level in wells (piezometer)
Electric contact meters
Datalogger
Different datalogger types for measuring stations with several measuring parameters (e.g. water temperature, water level, electr. conductivity of the water, ..); applicable for wells with diameters down to 1 ½ “ (Diver – Schlumberger; Micro, Compact, Gealog S - Logotronic)
