Note Dependencies when setting parameters!
‣ By means of the Flow meas. type/FLOW_TYPE ( ä 196) parameter, you can choose
between the following flow types:
• Volume process 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)
‣ The unit selected via the Flow unit/FLOW_UNIT ( ä 197) parameter must be
appropriate for the chosen flow type (Flow meas. type/FLOW_TYPE, ä 196).
‣ In the lower measuring range, small flow quantities (creepages) can lead to large
fluctuations in the measured value. By means of the Set. L. Fl. Cut-off/
CREEP_FLOW_SUPRESSION_OFF_THRES ( ä 198) parameter, you can configure a
low flow cut off.
Description
8Via the DP_FLOW Block:
Select via the Max. press. flow/
FLOW_MAX_PRESSURE parameter or
via the Pressure Transducer Block:
By means of the Scal In/SCALE_IN record
parameter, select the "Set URV/
E_PRESSURE_UPPER_RANGE_VALUE" element.
Enter the maximum pressure, here 400 mbar for
example. See also the layout sheet of the primary
device.
9 Set the Pressure Transducer Block and DP_FLOW
Block to the "Auto" block mode.
10 If necessary, configure the
Channel/CHANNEL ( ä 211),
Linearization Type/L_TYPE ( ä 212),
Transducer Scale/XD_SCALE ( ä 210) and
Output Scale/OUT_SCALE ( ä 211) parameters
by means of the Analog Input Block.
11 Result:
The device is configured for flow measurement.
