Instructions for installation (except level)

Conditions
Note
Compare the desired operating data with the data on the nameplate.
Please also refer to the information on the remote seal if this is fitted.
Note
Protect the transmitter against:
• Direct heat radiation
• Rapid temperature fluctuations
• Heavy contamination
• Mechanical damage
• Direct sunlight
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.
