Endress+Hauser Cerabar M - 9.8 Flow Measurement (Deltabar M)

Cerabar M, Deltabar M, Deltapilot M Commissioning with the FF configuration program
Endress+Hauser 155
9.8 Flow measurement (Deltabar M)
In this chapter the parameter text as well as the parameter name are indicated.
In FF configuration programs only the parameter text is displayed (exception: in the NI-
FBUS configurator you can select if the parameter text or the parameter name is displayed).
Example:
9.8.1 Adjustment
Example:
In this example, a volume flow should be measured in m
3
/h.
• The "Flow measurement" measuring mode is only available for the Deltabar M differential
pressure transmitter.
• For a description of the parameters mentioned, see

Description
1 Before configuring the device for your application,
the pressure piping must be cleaned and the device
filled with medium.

A See Table, step 7.
B See Table, step 8.
2 Open the Pressure Transducer Block and DP_FLOW
Block and set the block mode to OOS.
3 Select the measuring mode if necessary:
• Select the "Flow" option via the Primary Value
Type/PRIMARY_VALUE_TYPE parameter.
4 By means of the Press. eng. unit/CAL_UNIT
parameter or via Scale In/SCALE_IN, select a
pressure unit, here mbar for example.
5Via the DP_FLOW Block:
Select the "Volume operat. cond." option via the Flow
meas. type/FLOW_TYPE parameter.
6Via the DP_FLOW Block:
By means of the Flow unit/FLOW_UNIT parameter,
select a flow unit, here m
3
/h for example, or
via the Pressure Transducer Block:
By means of the Scale In/SCALE_IN record
parameter, select the "Press. eng. unit/
PRESSURE_1_UNIT" element.
7Via the DP_FLOW Block:
By means of the Flow Max/MAX_FLOW parameter,
select the EU_100 element or
via the Pressure Transducer Block:
By means of the Scale Out/SCALE_OUT record
parameter, select the "EU at 100% /
E_ENGINERING_UNIT_100_PERCENT" element.
Enter the maximum flow value of the primary
device, here 6000 m
3
/h for example. See also the
layout sheet of the primary device.
