THE COOL ONE 9
4 Installation
For all work performed on the level sensor, observe the
national safety regulations and accident prevention
regulations as well as all the safety instructions in this
manual of operating instructions.
For the installation and operation of the level sensor, the
regulations of the equipment safety law as well as the
generally recognised rules and regulations of technology
and this manual of operating instructions shall prevail.
For the installation of the level sensor, make sure that the
response point is not located in areas of intensive gas
flow.
The installation position of the level sensor in the container
must be selected so that neither splashes of liquid nor excessive
gas flow can result in premature response of the level sensor.
The level sensor should be installed as perpendicularly as
possible so that any residual liquid can drop down from the
detector.
With the permissible filling degree in the container, you define
the response height (A) of the level sensor (types 1 and 2) (see
Fig. 2). The response length of the level sensor type 3 is not va-
riable (see Chap. 6 "Technical data").
When using the level sensor as an overfilling safety device,
the permissible filling degree is calculated according to
TRbF (technical rules and regulations for flammable liquids)
280, Section 2.2. Take into account the switching delay
tim
e (see Chap. 6 "Technical data").
Each probe length (Z) is permanently impressed at the top end
of the probe. The probe length is provided as a distance
dimension between this mark and the response point of the
level sensor. (see Fig. 2)
