Sys. - Permanent
Storage
read only This parameter indicates whether automatic, permanent storage of
parameter changes in the EEPROM is switched on or off.
Display:
OFF
ON
Factory setting:
ON
" Caution!
• The option selected in this function can only be changed by the
Endress+Hauser service organization.
• If OFF is selected, all parameter changes are not permanently stored in the
EEPROM. This means that these parameter changes are no longer
available after a power failure. In these instances, the device starts with
the parameter configurations last stored in the EEPROM.
EPD -
Empty Pipe
Detection
AUTO - OOS Use this parameter to activate the empty pipe detection (EPD). With empty
measuring tubes the density of the fluid falls below the specified value in the
"EPD - Low Value" parameter.
Options:
OFF
ON
Factory setting:
OFF
" Caution!
• Select a correspondingly low EPD response value in the "EPD - Low
Value" parameter so that the difference to the effective density of the fluid
is sufficiently large. This ensures that totally empty measuring tubes and
not partially filled ones are detected.
• For gas measurement, we strongly recommend you switch off empty pipe
detection.
EPD -
Low Value
AUTO - OOS Use this parameter to specify a lower threshold value (limit value) for the
measured density as process problems can occur if the density is too low.
User input:
5-digit floating-point number
Factory setting:
0.2000
EPD -
High Value
AUTO - OOS Use this parameter to set an upper threshold for the measured density value.
User input:
5-digit floating-point number
Factory setting:
6.0000
EPD -
Unit
read only Displays the unit of the empty pipe detection (EPD).
! Note!
The unit is taken from the parameter "System Unit - Density"
( → Page 116).
