3.5 Installing Deltapilot M
!
Note!
• Due to the orientation of the Deltapilot M, there may be a shift in the zero point, i.e. when the
container is empty or partially full, the measured value does not display zero. You can correct this
zero point shift ä 40, Section "Function of the operating elements" or ä 56, Section 6.4
"Position zero adjustment".
• The local display can be rotated in 90° stages.
• Endress+Hauser offers a mounting bracket for installing on pipes or walls.
ä 15, Section 3.3.5 "Wall and pipe mounting (optional)".
3.5.1 General installation instructions
!
Note!
• Do not clean or touch process isolating diaphragms with hard or pointed objects.
• The process isolating diaphragm in the rod and cable version is protected against mechanical
damage by a plastic cap.
• If a heated Deltapilot M is cooled during the cleaning process (e.g. by cold water), a vacuum
develops for a short time, whereby moisture can penetrate the sensor through the pressure
compensation (1). If this is the case, mount the Deltapilot M with the pressure compensation (1)
pointing downwards.
• Keep the pressure compensation and GORE-TEX
®
filter (1) free from contamination.
• The device must be installed as follows in order to comply with the cleanability requirements of
the ASME-BPE (Part SD Cleanibility).:
