3.3 Installing Cerabar M
!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 ä40, Section "Function of the operating elements" or ä56, Section 6.4
"Position zero adjustment".
• For PMP55, please refer to Section 3.3.2 "Installation instructions for devices with diaphragm
seals – PMP55", ä12.
• Endress+Hauser offers a mounting bracket for installing on pipes or walls.
ä15, 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®filter (1) free from contamination.
• 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.

• Always install the Cerabar M below the lowest measuring point.
• Do not mount the device in the filling curtain or at a point in the tank which could be affected by
pressure pulses from an agitator.
• Do not mount the device in the suction area of a pump.
• The calibration and functional test can be carried out more easily if you mount the device
downstream of a shutoff device.
PVDF interchangeable threaded boss
!Note!
A maximum torque of 7 Nm (5.16 lbs ft) is permitted for devices with a PVDF interchangeable
threaded boss. The thread connection may become loose at high temperatures and pressures. This
means that the integrity of the thread must be checked regularly and may need to be tightened using
the torque given above. Teflon tape is recommended for sealing the 1/2 NPT thread.
3.3.2 Installation instructions for devices with diaphragm seals –
PMP55
!Note!
• Cerabar M devices with diaphragm seals are screwed in, flanged or clamped, depending on the
type of diaphragm seal.
• 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.
• 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.
• 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 mm (3.94 in)).
• 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. ä56, Section 6.4 "Position zero
adjustment".
• 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:
• Vibration-free (in order to avoid additional pressure fluctuations)
• Not in the vicinity of heating or cooling lines
• Insulate if the ambient temperature is below or above the reference temperature
• With a bending radius of 100 mm (3.94 in).

Cerabar M, Deltabar M, Deltapilot M / 4...20 mA HART Installation
Endress+Hauser 13
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 filling oil in the capillaries.
When the pressure transmitter is mounted above the diaphragm seal, the maximum height
difference H1 in accordance with the illustration below left must not be exceeded. 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 container), see illustration below right.
Mounting with temperature isolator
P01-PMx5xxxx-11-xx-xx-xx-008
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. 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 zero point shift of approx. 21 mbar (0.315 psi)
due to the hydrostatic column in the temperature isolator. You can correct this zero point shift.

A1 See the "Welding recommendation" table below
Endress+Hauser recommends welding on the diaphragm seal as follows for the "XSJ - Prepared for
diaphragm seal mount" version in feature 110 "Process connections" in the order code up to, and
including, 40 bar sensors: the total welding depth of the fillet weld is 1 mm (0.04 in) with an outer
diameter of 16 mm (0.63 in). Welding is performed according to the WIG method.
Information on filling
The diaphragm seal must be filled as soon as it has been welded on.
• After welding into the process connection, the sensor assembly must be properly filled with a
filling oil and sealed gas-tight with a sealing ball and lock screw.
Once the diaphragm seal has been filled, the device display should not exceed 10% of the full scale
value of the cell measuring range at the zero point. The internal pressure of the diaphragm seal
must be corrected accordingly.
• Adjustment / calibration:
– The device is operational once it has been fully assembled.
– Once the device has been switched on, the total reset code (7864) must be entered in the path:
"Expert" "System" "Management" "Enter reset code (124)" (see also Section 5.3.7).
The electronics then read all the specific sensor data out of the sensor electronics. The device
then has to be calibrated to the process measuring range as explained in the Operating
Instructions.

3.4 Installing Deltabar M
3.4.1 Installation position
!Note!
• 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 (ä40, "Function of the operating
elements")
– via the operating menu (ä56, "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 (ä23, "Wall and
pipe-mounting (option)").
