5 Installation
5.1 Mounting requirements
5.1.1 General installation instructions
• Devices with a G 1 1/2 thread:
When screwing the device into the tank, the flat seal has to be positioned on the sealing
surface of the process connection. To avoid additional strain on the process membrane, the
thread should never be sealed with hemp or similar materials.
• Devices with NPT threads:
• Wrap Teflon tape around the thread to seal it.
• Tighten the device at the hexagonal bolt only. Do not turn at the housing.
• Do not overtighten the thread when screwing. Max. tightening torque:
20 to 30 Nm (14.75 to 22.13 lbf ft)
• For the following process connections, a tightening torque of max. 40 Nm (29.50 lbf ft) is
specified:
• Thread ISO228 G1/2 (Order option "GRC" or "GRJ" or "G0J")
• Thread DIN13 M20 x 1.5 (Order option "G7J" or "G8J")
5.1.2 Mounting measuring cell modules with PVDF thread
LWARNING
Risk of damage to process connection!
Risk of injury!
‣Measuring cell modules with PVDF thread must be installed with the mounting bracket
provided!
LWARNING
Material fatigue from pressure and temperature!
Risk of injury if parts burst! The thread can become loose if exposed to high pressure and
temperature loads.
‣The integrity of the thread must be checked regularly. Also, the thread may need to be re-
tightened with the maximum tightening torque of 7 Nm (5.16 lbf ft). Teflon tape is
recommended for sealing the ½" NPT thread.

5.2 Installation instructions for devices without diaphragm seals –
PMP51, PMC51
NOTICE
Damage to the device!
If a heated device is cooled during a cleaning process (e.g. by cold water), a vacuum develops
for a short time and, as a result, moisture can enter the measuring cell through the pressure
compensation element (1).
‣Mount the device as follows.

A0028471
• 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 water pocket
pipes. The orientation depends on the measuring application.
• Do not clean or touch the membrane 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):

Cerabar M PMC51, PMP51, PMP55 IO-Link Installation
Endress+Hauser 9
A0028472
5.2.1 Pressure measurement in gases
Mount the Cerabar M with the shutoff device above the tapping point so that any condensate
can flow into the process.
5.2.2 Pressure measurement in vapors
• Mount the Cerabar M with the water pocket pipe below the tapping point.
• Fill the water pocket pipe with liquid before commissioning. The water pocket pipe reduces
the temperature to almost ambient temperature.
5.2.3 Pressure measurement in liquids
Mount the Cerabar M with the shutoff device below or at the same level as the tapping point.
5.2.4 Level measurement
• Always install the device below the lowest measuring point.
• Do not install the device at the following positions:
• in the filling curtain
• in the tank outlet
• in the suction area of a pump
• at a point in the tank which could be affected by pressure pulses from the agitator
• The calibration and functional test can be carried out more easily if you mount the device
downstream of a shutoff device.

Installation Cerabar M PMC51, PMP51, PMP55 IO-Link

5.3 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 membrane of the diaphragm seal with hard or pointed
objects.
• Do not remove the protection on the process membrane until just before installation.
NOTICE
Incorrect 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.
‣If a mounting bracket is used, sufficient strain relief must be ensured for the capillaries in
order to prevent them from buckling (bending radius ≥ 100 mm (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.
NOTICE
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
‣Mount with a bending radius ≥ 100 mm (3.94 in)!
‣Do not use the capillaries as a carrying aid for the diaphragm seals!

A 4-line liquid crystal display (LCD) is used for display and operation. The local display shows
measured values, dialog texts, fault messages and notice messages. For easy operation the
display can be taken out of the housing (see figure steps 1 to 3). It is connected to the device
via a 90 mm (3.54 in) long cable. The display of the device can be turned in 90° stages (see
figure steps 4 to 6). Depending on the installation position of the device, this makes it easy to
operate the device and read the measured values.
