CUST. UNIT FACT. F (609)
Entry
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 CUSTOMER UNIT F.
Prerequisite:
• UNIT FLOW = User unit
• NORM FLOW UNIT = User unit
• STD. FLOW UNIT = User unit
• MASS FLOW UNIT = User unit
Example:
– You want the measured value to be displayed in "bucket/h".
– MEASURED VALUE =0.01 m3/s
i
3600 bucket/h
– Entry CUSTOMER UNIT F: bucket/h
– Entry CUST. UNIT FACT. F: 360000
– Result: MEASURED VALUE = 3600 bucket/h
Factory setting:
1.0
MAX. FLOW (311)
Entry
Enter maximum flow of primary element.
See also layout sheet of primary element. The maximum flow is assigned to the
maximum pressure which you enter via MAX PRESS. FLOW.
!
Note!
Use the LINEAR/SQROOT parameter (
Page 113) to specify the current signal for the
"Flow" measuring mode. The following applies for the "Flow (square root)" setting:
If you enter a new value for MAX. FLOW, the value for SET URV is also changed. Use
SET URV to assign a flow to the upper current value. If you want to assign the upper
current value a value other than that for MAX. FLOW, you must enter the desired value
for SET URV. (
SET URV, Page 100).
Factory setting:
1.0
MAX PRESS. FLOW (634)
Entry
Enter maximum pressure of primary element.
See layout sheet of primary element. This value is assigned to the maximum flow value
(
see MAX. FLOW).
!
Note!
Use the LINEAR/SQROOT parameter (
Page 113) to specify the current signal for the
"Flow" measuring mode. The following applies for the "Differential pres." setting:
If you enter a new value for MAX PRESS. FLOW, the value for SET URV is also changed.
Use SET URV to assign a pressure value to the upper current value. If you want to assign
the upper current value a value other than that for MAX PRESS. FLOW, you must enter
the desired value for SET URV. (
SET URV, Page 100).
Factory setting:
High sensor limit (
see PRESS. SENS HILIM, Page 119)
DAMPING VALUE (247)
Entry
Enter damping time (time constant
).
The damping affects the speed at which all subsequent elements, such as the on-site
display, measured value and current output react to a change in the pressure.
Input range:
0.0...999.0 s
Factory setting:
2.0 s or as per order specifications
