2.2.4 Inlet/outlet runs
The thermal dispersion principle is sensitive to disturbed flow conditions.
As a general rule, the installed thermal flow sensor should always be installed as far away as
possible from any flow disturbances. Further information is provided in ISO Standard 14511.
m In the case of saturated or unclean gases, upward flow in a vertical pipe section is preferred to minimize
condensation/contamination.
n Not recommended if the vibrations are too high or if the installation is unstable.
o Only suitable for clean/dry gases. On horizontal pipes do not mount the sensor from the bottom, if the gas is very damp
or saturated with water (e. g. Bio Gas). Mount the sensor in a position as indicated below (α=135°).

4.2 Terminating resistors
!Note!
If the measuring device is used at the end of a bus segment, termination is required.
This can be performed in the measuring device by setting the terminating resistors on the I/O
board. Generally, however, it is recommended to use an external bus terminator and not
perform termination at the measuring device itself.
Has to be set for measuring devices with the following communication methods:
• PROFIBUS DP
– Baudrate ≤ 1.5 MBaud →Termination can be performed at the measuring device, see
graphic
– Baudrate > 1.5 MBaud →An external bus terminator must be used
• MODBUS RS485 →Termination can be performed at the measuring device, see graphic
#Warning!
Risk of electric shock! Risk of damaging the electronic components!
• All the safety instructions for the measuring device must be observed and all the warnings
heeded →ä3.
• Use a workspace, working environment and tools purposely designed for electrostatically
sensitive devices.
