NOTICE

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,  Chap. "Function of the operating elements" or  ä 86,  Chap. 8.3 "Position zero adjustment".

• For PMP55, please refer to Section 4.5.2 "Installation instructions for devices with diaphragm seals – PMP55",  ä 18.

• Endress+Hauser offers a mounting bracket for installing on pipes or walls.  ä 22,  Chap. 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

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:

‣ 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). ‣ Do not use the capillaries as a carrying aid for the diaphragm seals!

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

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 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, 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 86, "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 30, "Wall and pipe-mounting (option)").
