Abstract
The salt dilution method is suitable for measurement of flow in open channel. However, the customary method is based on the temporary and inaccurate data obtained by some preparatory measurements, and accordingly the method is unreliable in spite of the complicated procedures.
We present in this paper fine conductivity data of brine, useful for the salt dilution method.
Utilising the data, the salt dilution method becomes more reasonable and simpler, without the preliminary experiments and the procedure of calibration, which are necessary for the customary method.
Moreover, these conductivity data improve the accuracy and reproduction of flow measurements.
Some practical ideas to achieve uniform distribution of injected brine are proposed.
