Attention: Avoid placing the sensors in mud or high vegetation, prevent the sensors
from floating in the water and avoid positions where air bubbles are
present.
The tracer substance has to be mixed up completely. For this purpose, choosing longer
mixing distances is better than shorter ones and using bigger amounts of tracer
substance is preferred to using smaller amounts. Tracer flowing through the sensors has
to be clearly visible in the measurement results and the maximum deflection must fulfill
the minimum requirement (> 200 µS/cm and/or 100% of the base value). After the tracer
passage the measured values should decrease to the base value.
