4.3.1 Installing the Container Probe
For installation of the probes, please keep in mind:

Select the installation site such that good mixing and a ho-
mogeneous product are ensured and no bubbles are present
in the probe. A sample tap should be available in the direct
vicinity to allow representative sampling.

The probe must be flanged to the container so that the ma-
terial to be measured flows between the two measuring
rods. That means the fork (both measuring rods) must be
installed perpendicular to the material flow.

The distance between the measuring rod tips and any metal-
ized walls (heating element, stirrer, container wall) should
be at least
60 mm .

The following mounting hole dimensions in the fitting
flange are required for installation of the probe:
Flange Minimum mounting hole size  (mm)
DN 65 / PN 6 102  0.3
others 104  0.5

For further installation dimensions, such as the required in-
stallation depth, please refer to
chapter 8.6 and 8.7 Assem-
bly Sheets .

Use the appropriate flat gasket (standard accessory) to
compensate for minor surface tolerances in the fitting
flange.
Installation on process containers
Figure 3-26 shows the position of the container probe on the
container. This position is also valid for the container flush
probe. Follow the instructions in
chapter 3.9 Assembly on a
Container.
The assembly sheets in chapters 8.6 and 8.7 include all the in-
formation required for installation.
Depending on the process, the probe flange may stick to the
process flange. In such case, during the dismounting process,
