Parameter description (FF configuration program) Cerabar S/Deltabar S/Deltapilot S FOUNDATION Fieldbus
84 Endress+Hauser
Customer Unit F/
CUSTOMER_UNIT_
FLOW
Entry
Index: 17
Data type: visible string
Access: read, write
Enter text (unit) for customer-specific flow unit.
You can enter a maximum of eight alphanumeric characters here.
→ See also Cust. Unit Fact. F/CUSTOMER_UNIT_FACTOR_FLOW.
Prerequisites:
• Deltabar S differential pressure transmitter
• Unit Flow/STD_FLOW_UNIT = User unit
!
Note!
Only the first five characters are shown on the local operation. For example, if "crates" is
specified as the customer-specific unit, "crate" is displayed.
If the unit contains a slash, up to eight characters can be shown on the local operation. The
maximum number of characters in the counter is again limited to five. For example, if
"crates/m2" is specified as the customer-specific unit, "crate/m2" is displayed. In the
FF configuration program, the slash counts as a character, i.e. "crates/m2" would be
displayed as "crates/m".

Cust. Unit Fact. F/
CUSTOMER_UNIT_
FACTOR_FLOW
Entry
Index: 18
Data type: float
Access: read, write
Enter the conversion factor for a customer-specific flow unit. The conversion factor must be
entered in relation to an appropriate SI unit, e.g. "m³/s" for the "Volume operat. cond." flow
mode.
→ See also Customer Unit F/CUSTOMER_UNIT_FLOW.
Prerequisite:
• Deltabar S differential pressure transmitter
• Unit Flow/STD_FLOW_UNIT = User unit
Example:
– You want the measured value to be displayed in "bucket/h".
– Primary Value/PRIMARY_VALUE = 0.01 m3/s i 3600 bucket/h
– Enter Customer Unit F/CUSTOMER_UNIT_FLOW: bucket/h
– Enter Cust. Unit Fact. F/CUSTOMER_UNIT_FACTOR_FLOW: 360000
– Result: Primary Value/PRIMARY_VALUE = 3600 bucket/h
Factory setting:

Low Flow Cut-Off/
LOW_FLOW_CUT_OFF
Selection
Index: 19
Data type: UNSIGNED8
Access: read, write, OOS
Switch the "low flow cut-off" function on and off.
In the lower measuring range, small flow quantities (creepages) can lead to large fluctuations
in the measured value. Switching on this function stops these flow quantities from being
recorded. → ä 85, Set. L. Fl. Cut-Off/SET_LOW_FLOW_CUT_OFF.
