Siemens SITRANS DS III Series Compact Operating Instructions page 15

The installation location is to be as follows:
● Easily accessible
● As close as possible to the measuring point
● Vibration-free
● Within the permitted ambient temperature values
Installation configuration
The transmitter may in principle be configured above or below the pressure tapping point. The recommended configuration
depends on the aggregate state of the medium.
Installation configuration for gases
Install the transmitter above the pressure tapping point.
Lay the pressure tubing with a constant gradient to the pressure tapping point, so that any condensation produced can drain
in the main line and thereby avoid corruption of the measured values.
Installation configuration for vapor and liquid
Install the transmitter below the pressure tapping point.
Lay the pressure tubing with a constant gradient to the pressure tapping point so that any gas pockets can escape in the
main line.
3.3.2 Installation (except level)
Note
Damage to measuring cell
When installing the process connection of the pressure transmitter, do not rotate the housing. Rotating the housing may
damage the measuring cell.
To avoid damage to the device, tighten the threaded nuts of the measuring cell using a wrench.
Procedure
Attach the transmitter to the process connection with an appropriate tool.
