Function group "basic setup" (00)
Function "tank properties" (002)
This function is used to select the tank properties.
Selection:
•
standard
•
aluminium tank
•
plastic tank
•
bypass / pipe
•
coax probe
•
concrete wall
standard
The "
standard
" option is recommended for normal containers for rod and rope probes.
aluminium tank
The "
aluminium tank
" option is designed especially for high aluminium silos that cause
an increased level of noise when empty. This option is only useful for probes
longer than (< 4 m). For short probes (< 4 m) select the "
standard
" option.
!
Note!
If "
aluminium tank
" is selected, the device calibrates of its own accord when first filled,
depending on the medium's properties. Slope errors can, therefore, occur when begin-
ning the first filling procedure.
plastic tank
Select the "
plastic tank
" option when installing probes in wood or plastic containers
wit-
hout
metallic surfaces at the process connection (see installation in plastic containers).
When using a metallic surface at the process connection, the "
standard
" option is suffi-
cient.
!
Note!
In principle the employment of a metallic surface area should be preferred at the pro-
cess connection!
