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

Description
Due to the orientation of the device, there may be a shift in the measured value, i.e. when the container is empty or partly
filled, the measured value does not display zero. Deltabar S and Cerabar S offer three different ways of performing a
position adjustment.
Recommendation:
• The pressure difference between zero (set point) and the measured pressure need not be known.
– POS. ZERO ADJUST: Deltabar S or Cerabar S with gauge pressure sensor or Deltapilot S.
– POS. INPUT VALUE: Cerabar S with absolute pressure sensor.
• The pressure difference between zero (set point) and the measured pressure is known.
– CALIB. OFFSET: Deltabar S, Cerabar S with gauge pressure sensor, Cerabar S with absolute pressure sensor or
Deltapilot S.
