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)
