Siemens 7MF8 23-Serie Kompaktbetriebsanleitung Seite 12

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 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.
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.
