Installation instructions

Note!
• Due to the orientation of the Cerabar 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 25, Section 5.1.2 "Function of the operating elements".
• For PMP55, please refer to Section 3.3.2 "Installation instructions for devices with diaphragm
seals – PMP55",  ä 12.
• Endress+Hauser offers a mounting bracket for installing on pipes or walls.
 ä 15, Section 3.3.5 "Wall and pipe mounting (optional)".
3.3.1 Installation instructions for devices without diaphragm seals –
PMP51, PMC51
Note!
• If a heated Cerabar 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 Cerabar M with the pressure compensation (1)
pointing downwards.
• Keep the pressure compensation and GORE-TEX
• Cerabar M transmitters without diaphragm seals are mounted as per the norms for a manometer
(DIN EN 837-2). We recommend the use of shutoff devices and siphons. The orientation depends
on the measuring application.
• Do not clean or touch process isolating diaphragms with hard or pointed objects.
