4.5 Installing Cerabar M
• 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 47, Section "Function of the operating elements" or
ä 64, Section 8.4 "Position zero adjustment".
• For PMP55, please refer to Section 4.5.2 "Installation instructions for devices with
diaphragm seals – PMP55", ä 17.
• Endress+Hauser offers a mounting bracket for installing on pipes or walls.
ä 21, Section 4.5.5 "Wall and pipe mounting (optional)".
4.5.1 Installation instructions for devices without diaphragm seals –
PMP51, PMC51
Damage to the device!
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.
• The device must be installed as follows in order to comply with the cleanability
requirements of the ASME-BPE (Part SD Cleanability):
filter (1) free from contamination.

NOTICE
NOTICE
4.5.2 Installation instructions for devices with diaphragm seals –
PMP55
• Cerabar M devices with diaphragm seals are screwed in, flanged or clamped, depending on
the type of diaphragm seal.
• Please note that the hydrostatic pressure of the liquid columns in the capillaries can cause
zero point shift. The zero point shift can be corrected.
• Do not clean or touch the process isolating diaphragm of the diaphragm seal with hard or
pointed objects.
• Do not remove process isolating diaphragm protection until shortly before installation.
Improper handling!
Damage to the device!
‣ A diaphragm seal and the pressure transmitter together form a closed, oil-filled
calibrated system. The fill fluid hole is sealed and may not be opened.
‣ When using a mounting bracket, sufficient strain relief must be ensured for the
capillaries in order to prevent the capillary bending down (bending radius 100
(3.94 in)).
‣ Please observe the application limits of the diaphragm seal filling oil as detailed in the
Technical Information for Cerabar M TI00436P, "Planning instructions for diaphragm
seal systems" section.
In order to obtain more precise measurement results and to avoid a defect in the device,
mount the capillaries as follows:

Vacuum application
For applications under vacuum, Endress+Hauser recommends mounting the pressure
transmitter below the diaphragm seal. This prevents vacuum loading of the diaphragm seal
caused by the presence of fill fluid in the capillary.
When the pressure transmitter is mounted above the diaphragm seal, the maximum height
difference H1 in accordance with the illustrations below must not be exceeded.
A0023994
Fig. 9: Installation above the lower diaphragm seal
The maximum height difference depends on the density of the filling oil and the smallest
ever pressure that is permitted to occur at the diaphragm seal (empty vessel), see illustration
below:

Mounting with temperature isolator
Endress+Hauser recommends the use of temperature isolators in the event of constant
extreme medium temperatures which lead to the maximum permissible electronics
temperature of +85 °C (+185°F) being exceeded.
Depending on the filling oil used, diaphragm seal systems with temperature isolators can be
used for maximum temperatures of up to 400 °C (+752 °F). For the temperature
application limits, see technical Information, "Diaphragm seal filling oils" section.
To minimize the influence of rising heat, Endress+Hauser recommends the device be
mounted horizontally or with the housing pointing downwards. The additional installation
height also brings about a maximum zero point shift of 21 mbar (0.315 psi) due to the
hydrostatic column in the temperature isolator. You can correct this zero point shift at the
device.
The temperature restrictions are lowest with an insulation height of 30 mm (1.18 inch).
Full insulation exhibits virtually the same behavior as no insulation!
The temperature limits with an insulation height of 30 mm (1.18 inch) are illustrated in the
following graphic.

Information on filling
The diaphragm seal must be filled as soon as it has been welded on.
• After welded into the process connection, the sensor asse mbly must be p rop erl y fil led wit h
a filling oil and sealed gas-tight with a sealing ball and lock screw.
Once the diaphragm seal has been filled, at the zero point the device display should not
exceed 10% of the full scale value of the cell measuring range. The internal pressure of the
diaphragm seal must be corrected accordingly.
• Adjustment / calibration:
– The device is operational once it has been fully assembled.
– Perform a reset. The device must then be calibrated to the process measuring range as
described in the Operating Instructions.

4.6 Installing Deltabar M
Incorrect handling!
Damage of the device!
‣ Disassembly of the screws with item number (1) is not permissible under any
circumstances and will result in loss of warranty.
4.6.1 Installation position
• Due to the orientation of the Deltabar M, there may be a shift in the measured value, i.e.
when the container is empty, the measured value does not display zero. You may correct
this zero point shift by a position adjustment in one of the following ways:
– via the operation keys on the electronics module ( ä 47, "Function of the operating
elements")
– via the operating menu ( ä 64, "Position zero adjustment")
• General recommendations for routing the impulse piping can be found in DIN 19210
"Methods for measurement of fluid flow; differential piping for flow measurement devices"
or the corresponding national or international standards.
• Using a three-valve or five-valve manifold allows for easy commissioning, installation and
maintenance without interrupting the process.
• When routing the impulse piping outdoors, ensure that sufficient anti-freeze protection is
used, e.g. by using pipe heat tracing.
• Install the impulse piping with a monotonic gradient of at least 10%.
• Endress+Hauser offers a mounting bracket for installing on pipes or walls ( ä 29, "Wall
and pipe-mounting (option)").
