FLOW_UNIT_TEXT/
CUSTOMER UNIT F
Entry
Index: 70
Data type: Visible String
Access: Auto, OOS
Enter text (unit) for customer-specific flow unit.
You can enter a maximum of eight alphanumeric characters here. → See also
FLOW_UNIT_SCALE/CUST. UNIT FACT. F.
Prerequisite:
• Deltabar S differential pressure transmitter
• FLOW_UNIT/UNIT FLOW = user unit
!
Note!
Only the first five characters are shown on the on-site display. 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 on-site display. 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".

FLOW_UNIT_SCALE/
CUST. UNIT FACT. F
Entry
Index: 71
Data type: Float
Access: Auto, OOS
Enter conversion factor for a customer-specific flow unit. The conversion factor must be
entered in relation to an appropriate SI unit, e.g. m
3
/s for the "Volume p. cond." flow
mode.→ See also FLOW_UNIT_TEXT/CUSTOMER UNIT F.
Prerequisite:
• Deltabar S differential pressure transmitter
• FLOW_UNIT/UNIT FLOW = user unit
Example:
– You want the measured value to be displayed in "bucket/h".
– PRIMARY_VALUE =0.01 m3/s i 3600 bucket/h
– Entry FLOW_UNIT_TEXT/CUSTOMER UNIT F.: bucket/h
– Entry FLOW_UNIT_SCALE/CUST. UNIT FACT. F: 360000
– Result: PRIMARY_VALUE = 3600 bucket/h
Factory setting:
1.0
CREEP_FLOW_
SUPPRESSION_ENABLE
/LOW FLOW CUT-OFF
Selection
Index: 72
Data type: Unsigned8
Access: Auto, OOS
Switches "low flow cut-off" function on and off.
In the lower measuring range, small flow quantities (creepages) can lead to large measured
value fluctuations. Switching on this function stops these flow quantities from being
recorded. → See also Page 49, LOW_FLOW_CUT_OFF/SET. L. FL. CUT-OFF.
Prerequisite:
• Deltabar S differential pressure transmitter
Options:
•Off
•On
