Endress+Hauser Proline Prowirl 73 - HART Input Functions

Proline Prowirl 73 Description of device functions
Endress+Hauser 167
11.19 HART INPUT
Function description, HART INPUT group
Prowirl can read in an external pressure, temperature or density value with the HART INPUT function. The external
value can be read in at a rate of up to three values per second. For a detailed connection diagram, see ä 30
Prerequisite
• This mode is not possible for transmitters that are HART-enabled but NOT burst-enabled (e.g. iTemp 162).
• The HART INPUT group is only available if OFF was selected in the BURST MODE function (ä 138).

Note!
If you are using Prowirl 73 electronics on a Prowirl 72 meter body and DSC sensor,
select the PRESSURE 72, TEMPERATURE 72 or DENSITY 72 setting. With these
options, Prowirl 73 fluid temperature measurement is ignored.
Select the option depending on the sensor used or the setting in SELECT FLUID
(ä 143):
Settings other than those indicated here are NOT possible in conjunction with the
SELECT FLUID (ä 143) function.
1)
The internal temperature measurement is used to compensate the K-factor.
2)
The external temperature measurement is used to compensate the K-factor.
3)
If a density value is read in, it is not possible to output the heat flow.
