INST. FACTOR
In narrow installation conditions, the conductivity
measurement is influenced by the sensor’s dis‑
tance to the wall and the wall material. This effect
can be compensated for by the installation factor.
The meter corrects the cell constant by multiplying
it with the installation factor. The value of the in‑
stallation factor depends on the diameter and the
conductivity of the pipe as well as on the sensor’s
distance from the wall. If the distance from the wall
is sufficient (> 15 mm (0.59"), DN 80 or larger), it
is not necessary to consider the installation factor
(1.00). If the distance from the wall is smaller, the
installation factor increases (> 1) when the pipe is
electrically insulating and decreases (< 1) when the
pipe is electrically conductive. See the instructions
in the sensor manufacturer’s documentation.
