Installation
3.3.1 Mounting the sensor
NOTE
The sensor is an optical precision instrument that should be protected against
shocks. Make sure that the distances to the wall, bottom and other installation
surroundings are sufficient. If necessary, protect the end of the sensor against
hitting with the protective ring provided. Mount any fixing elements only on the
sturdy metal shaft.
NOTE
Always make sure the surface of the enclosure is not damaged by sharp-edged
objects. The enclosure of the sensor may not touch any metallic objects in order
to prevent contact corrosion.
NOTE
Do not suspend the sensor on the sensor connection cable. Risk of cable break
and water penetration at the cable gland.
A wide range of mounting accessories is available for the installation of the
ColorVis 705 IQ (see chapter 6 S
). Thus, all prevalent ways of mounting are possible.
Generally, observe the following general rules when mounting the sensor at the
measuring location:
Horizontal
installation
When mounting the sensor horizontally, the measuring gap opening should be
on the side. Thus, any air bubbles can escape upward after cleaning and no sed
-
iment can collect in the measuring gap. The sensor should be aligned in parallel
with the flow direction.
