Installation (level)

Before you mount the device
• Compare the operating data with the data on the nameplate of the pressure transmitter.
• Observe the minimum and maximum permissible ambient and medium temperature limits
also under the influence of convection and heat radiation.
• Note the effect of the ambient temperature on the measuring accuracy in the
section Technical data (Page 63).
• For remote seal mounting, observe the notes in the section "Mounting with remote seal" of
the operating instructions.
Mounting location
Verify that the mounting location meets the following conditions:
• Accessible
• Close to the measuring point
• Vibration-free
• Within the permitted ambient temperature values
Protect the pressure transmitter from:
• Direct heat radiation
• Rapid temperature fluctuations
• Heavy contamination
• Mechanical damage
• Direct sunlight
Note
Select the height of the mounting flange such that the pressure transmitter is always mounted
below the lowest fill height to be measured.
Procedure
1. Attach the seal to the container's mating flange.
Ensure that the seal is centrally positioned and that it does not restrict the movement of the
flange's seal diaphragm in any way. Otherwise, the seal of the process connection is not
guaranteed to be tight.
2. Screw on the pressure transmitter's flange.
3. Observe the installation position.
