The installation location is to be as follows:
● Easily accessible
● As close as possible to the measuring point

Installation configuration
The transmitter may in principle be configured above or below the pressure tapping point.
The recommended configuration depends on 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
condensate produced can drain in the main line and thereby avoid corruption of the
measured values.
