Cerabar S/Deltabar S/Deltapilot S FOUNDATION Fieldbus Flow measurement (FF configuration program)
Endress+Hauser 35
!
Note!
1. By means of the Flow-Meas. Type/FLOW_MEAS_TYPE parameter (→ ä 82), you can choose
between the following flow types:
– Volume operat. cond. (volume under operating conditions)
– Gas norm. cond. (norm volume under norm conditions in Europe: 1013.25 mbar and
273.15 K (0 °C))
– Gas std. cond. (standard volume under standard conditions in USA: 1013.25 mbar (14.7 psi)
and 288. 15 K (15 °C/59 °F))
– Mass p. cond. (mass under operating conditions)
2. The unit selected by means of the Unit Flow/STD_FLOW_UNIT parameter (→ ä 83) has to
suit the flow type selected (Flow-Meas. Type/FLOW_MEAS_TYPE, → ä 82).
3. In the lower measuring range, small flow quantities (creepages) can lead to large fluctuations
in the measured value. You can activate low flow cut-off via the Low Flow Cut-Off/
LOW_FLOW_CUT_OFF parameter (→ ä 84).
Description
9 Select the Scale In/SCALE_IN parameter, EU_100
element.
Enter the maximum pressure, here 400 mbar (6 psi) for
example. See also the layout sheet of the primary device.
10 Set the Pressure Transducer Block to the "Auto" block
mode.
11 Where necessary, configure the Channel/CHANNEL
(→ ä 96), Linearization Type/L_TYPE (→ ä 97),
Transducer Scale/XD_SCALE (→ ä 95) and Output
Scale/OUT_SCALE (→ ä 96) parameters by means of
the Analog Input Block.
12 Result:
The device is configured for flow measurement.
