2 Basic safety instructions
2.1 Requirements concerning the staff
The staff must fulfill the following requirements for their tasks:
►Trained staff: Must have a qualification which corresponds to their function and tasks.
►Authorized by the plant operator.
►Familiar with the national regulations.
►Before starting their work: Must have read and understood all instructions in the operating
manual and supplementary documentation as well as the certificate (depending on the
application).
►Must comply with all instructions and the regulatory framework.
2.2 Designated use
2.2.1 Application and media
The Deltabar FMD72 is a differential pressure transmitter for measuring differential pressure and
level in pressurized tanks. The device has two sensor modules, which measure the operating

Deltabar FMD72 Basic safety instructions
Endress+Hauser 7
pressure (High Pressure HP and Low Pressure LP). The differential pressure/hydrostatic level is
calculated in the transmitter unit. The sensor signal is transmitted digitally. In addition, sensor
temperatures and the individual process pressures present at the respective sensor modules can
be individually evaluated and transmitted. If the limit values specified in the "Technical Data"
and the conditions listed in the instructions and additional documentation are observed, the
measuring device may be used for the following measurements (process variables):
Measured process variables
• Pressure HP and Pressure LP
• Sensor temperature
Calculated process variables
• Differential pressure
• Level (level, volume or mass)
2.2.2 Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated use.
Verification for borderline cases:
►For special fluids and fluids for cleaning, Endress+Hauser is glad to provide assistance in
verifying the corrosion resistance of fluid-wetted materials, but does not accept any warranty
or liability.
2.2.3 Residual risks
Due to heat transfer from the process as well as power loss in the electronics, the temperature
of the electronics housing and the assemblies contained therein (e.g. display module, main
electronics module and I/O electronics module) may rise up to 80 °C (176 °F). When in
operation, the sensor may reach a temperature close to the medium temperature.
Danger of burns from contact with surfaces!
►For elevated fluid temperature, ensure protection against contact to prevent burns.
2.3 Workplace safety
For work on and with the device:
►Wear the required personal protective equipment according to federal/national regulations.
►Switch off the supply voltage before connecting the device.
2.4 Operational safety
Risk of injury!
►Operate the device in proper technical condition and fail-safe condition only.
►The operator is responsible for interference-free operation of the device.
Conversions to the device
Unauthorized modifications to the device are not permitted and can lead to unforeseeable
dangers
►If, despite this, modifications are required, consult with Endress+Hauser.

Product description Deltabar FMD72
8 Endress+Hauser
Repair
To ensure continued operational safety and reliability,
►Carry out repairs on the device only if they are expressly permitted.
►Observe federal/national regulations pertaining to repair of an electrical device.
►Use original spare parts and accessories from Endress+Hauser only.
Hazardous area
To eliminate a danger for persons or for the facility when the device is used in the hazardous
area (e.g. explosion protection, pressure vessel safety):
►Based on the nameplate, check whether the ordered device is permitted for the intended use
in the hazardous area.
►Observe the specifications in the separate supplementary documentation that is an integral
part of these Instructions.
2.5 Product safety
This measuring device is designed in accordance with good engineering practice to meet state-
of-the- art safety requirements, has been tested, and left the factory in a condition in which they
are safe to operate.
It fulfills general safety requirements and legal requirements. It also conforms to the EC directives
listed in the device-specific EC declaration of conformity. Endress+Hauser confirms this fact by
applying the CE mark.

Installation Deltabar FMD72
12 Endress+Hauser
6 Installation
When measuring in media containing solids, such as dirty liquids, installing separators and drain
valves is useful for capturing and removing sediment.
6.1 Mounting dimensions
For dimensions, see the "Mechanical construction" section in TI01033P.
6.2 Mounting location
The FMD72 is best suited to level measurement in tanks with pressure overlay, high distillation
columns and other containers with changing ambient temperatures.
The sensor module HP is mounted on the lower measuring connection and the sensor module
LP is mounted above the maximum level. The transmitter can be mounted on pipes or walls
with the mounting bracket.
6.3 Orientation
• Transmitter: Any orientation.
• Sensor modules: The orientation can cause a zero point shift .
This position-dependent zero point shift can be corrected directly at the device via the
operating key, and also in hazardous areas in the case of devices with external operation.
6.4 General installation instructions
Mounting the sensor modules and transmitter is very easy
• The housings of the sensor modules can be rotated up to 380°.
• The transmitter is freely rotatable in the mounting bracket.
The sensor modules and transmitter can be easily aligned when mounted.
Your benefits
• Easy to mount by optimally aligning the housing
• Good, accessible device operation
• Optimum readability of the onsite display (optional)
• Simple pipe installation through optional alignment of the modules

A0017506
6.5 Installing the sensor modules
• The nameplate on the sensor module specifies where the sensor module is typically installed:
HP (bottom)
LP (top)
For further information see the "Function" section.
• Due to the orientation of the sensor modules, 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: see "Commissioning without an operating menu"(® ä 28) or
the "Position adjustment" section(® ä 32) .
• Always install the sensor module HP below the lowest measuring point.
• Always install the sensor module LP above the highest measuring point.
• Do not mount the sensor modules 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 sensor modules in the suction area of a pump.
• The adjustment and functional test can be carried out more easily if you mount the sensor
modules downstream of a shutoff device.
• If a heated sensor module 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 (3). If this is the case, mount the sensor with the pressure compensation (3)
pointing downwards.
• Keep the pressure compensation and GORE-TEX® filter (3) free from contamination.
• Do not clean or touch process isolating diaphragms with hard or pointed objects.

NOTICE
Distorted measurement results.
The seal is not allowed to press against the process isolating diaphragm as this could affect the
measurement result.
►Ensure that the seal is not touching the process isolating diaphragm.
6.7 Installing the transmitter
The transmitter is installed with the mounting bracket supplied. The mounting bracket can be
installed on pipes with a diameter of 1¼" to 2" or on walls.
In the case of pipe mounting, the nuts on the bracket must be tightened uniformly with a torque
of at least 5 Nm (3.69 lbf ft).
