Cell constant and installation factor

The electrolytic conductivity of the liquid predominantly depends on the ion concentration.
The geometrical conditions of the sensor surroundings and the geometry of the sensor
itself have to be taken into consideration with the measurement.
The geometry of the sensor is fully described by the cell constant
The geometrical conditions of the sensor surroundings are described by the installation
[f] . The installation factor [f] does not need to be considered if the sensor head is

installation factor is higher than 1 with electrically isolating pipes (1) and lower than 1 with
electrically conducting pipes (2), see Fig. 3
