Installing/mounting
4.3 Installation (except level)
● 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.
4.3.2
Installation (except level)

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.
