A0016449

LP Sensor module LP (low pressure)
HP Sensor module HP (high pressure)
p2 Head pressure
p1 Hydrostatic pressure
1 Transmitter

The FMD71/FMD72 is best suited to level measurement in vessels with pressure overlay
or in vacuum vessels and tanks, high distillation columns and other vessels 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.

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.

NOTICE

Incorrect sizing/order of sensor modules

In a closed system, please note that the sensor module is affected by the superimposed

‣

head pressure (p2) in addition to the hydrostatic pressure (p1). This must be taken into
account when sizing the sensor module on the high-pressure side (HP).

All the process values represented on the diagram are updated in a measurement cycle.
The sensor module allocation is determined by the configuration when setting up the
device. The connection to the transmitter defines the corresponding sensor module as the
master. After commissioning, the second sensor module is detected as the slave. This
configuration can be modified as desired. However, a modification must take place with
the unit disconnected from the power supply.

The sensor modules have a designation independent of the master/slave configuration.
This indicates where the sensor module is typically installed:

• Sensor module LP

LP = Low pressure; top

• Sensor module HP

HP = High pressure; bottom

For identical sensor module ranges, this assignment can likewise be changed, but this then
has to be configured in the menu.

If you change both sensor modules or the electronics, this allocation must likewise be
carried out. See the "Transm. connect. (286)" parameter .

5.6 Installing the sensor modules

5.6.1 General installation instructions

• 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 →  13.

• Due to the orientation of the sensor modules, there may be a shift in the zero point, i.e.
when the vessel is empty or partially full, the measured value does not display zero.
You can correct this zero point shift: see the "Commissioning without an operating menu"
→  42or the "Position adjustment"→  47 section.

• 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.

7.2 Operation with an operating menu

7.2.1 Operation concept

Operation with an operating menu is based on an operation concept with "user roles" .

User role Meaning

Operator Operators are responsible for the devices during normal "operation". This is usually limited to

reading process values either directly at the device or in a control room. If the work with the
devices extends beyond value read-off tasks, the tasks involve simple, applicationspecific
functions that are used in operation. Should an error occur, these users simply forward the
information on the errors but do not intervene themselves.

Maintenance Service engineers usually work with the devices in the phases following device commissioning.

They are primarily involved in maintenance and troubleshooting activities for which simple
settings have to be made at the device. Technicians work with the devices over the entire life
cycle of the product. Thus, commissioning and advanced settings and configurations are some of
the tasks they have to carry out.

Expert Experts work with the devices over the entire life cycle of the device, but, at times, have high

device requirements. Individual parameters/functions from the overall functionality of the
devices are required for this purpose time and again. In addition to technical, process-oriented
tasks, experts can also perform administrative tasks (e.g. user administration). "Experts" can
access the entire parameter set.

7.3 Structure of the operating menu

User role Submenu Meaning/use

Operator Language Only consists of the "Language" parameter (000) where the operating language for

the device is specified. The language can always be changed even if the device is
locked.

Operator Display/

operat.

Maintenance Setup Contains all the parameters that are needed to commission measuring operations.

Contains parameters that are needed to configure the measured value display
(selecting the values displayed, display format, display contrast, etc.). With this
submenu, users can change the measured value display without affecting the actual
measurement.

This submenu has the following structure:

• Standard setup parameters
A wide range of parameters, which can be used to configure a typical application,
is available at the start. The measuring mode selected determines which
parameters are available. After making settings for all these parameters, the
measuring operation should be completely configured in the majority of cases.

• "Extended setup" submenu
The "Extended setup" submenu contains additional parameters for more indepth
configuration of the measurement operation to convert the measured value and
to scale the output signal. This menu is split into additional submenus depending
on the measuring mode selected.

Maintenance Diagnosis Contains all the parameters that are needed to detect and analyze operating errors.

This submenu has the following structure:

• Diagnostic list

integration into a distributed control system.

• Measurement
Contains all the parameters for configuring the measurement.

• Output

9.10.4 "In pressure" level selection Calibration without reference pressure (dry calibration)

Example:

In this example, the volume in a tank should be measured in liters. The maximum volume
of 1 000 l (264 gal) corresponds to a pressure of 450 mbar (6.53 psi).

The minimum volume of 0 liters corresponds to a pressure of 50 mbar (0.73 psi) since the
device is mounted below the start of the level measuring range.

Prerequisite:

• The measured variable is in direct proportion to the pressure.

• This is a theoretical calibration i.e. the pressure and volume values for the lower and

upper calibration point must be known.

• The values entered for "Empty calib./Full calib.", "Empty pressure/Full pressure" and
"Set LRV/Set URV" must be at least 1% apart. The value will be rejected, and a
warning message displayed, if the values are too close together. Further limit values
are not checked, i.e. the values entered must be appropriate for the sensor module
and the measuring task for the device to be able to measure correctly.

• Due to the orientation of the device, there may be pressure shifts in the measured
value, i.e. when the vessel is empty or partly filled, the measured value is not zero.

9.10.5 "In height" level selection Calibration with reference pressure (wet calibration)

Example:

In this example, the volume in a tank should be measured in liters. The maximum volume
of 1 000 l (264 gal) corresponds to a level of 4.5 m (15 ft).

The minimum volume of 0 liters corresponds to a level of 0.5 m (1.6 ft) since the device is
mounted below the start of the level measuring range. The density of the fluid is 1 g/cm
(1 SGU).

Prerequisite:

• The measured variable is in direct proportion to the pressure.

• The tank can be filled and emptied.

The values entered for "Empty Calib./Full Calib.", "Set LRV/Set URV", and the applied
pressure values must be at least 1% apart. The value will be rejected, and a warning
message displayed, if the values are too close together. Further limit values are not
checked, i.e. the values entered must be appropriate for the sensor module and the
measuring task for the device to be able to measure correctly.

During this wet calibration, a level of 20% is used as the calibration point for "Empty" and a
level of "80%" is used as the calibration point for "Full".

The calibration is then extended to 0% to 100% and lower range-value (LRV)/upper
range-value (URV) are adapted accordingly.

• Only specialist personnel or Endress+Hauser-Service can carry out repairs to Ex certified
devices.

• Relevant standards and national regulations as well as safety instructions (XA) and
certificates must be observed.

• Only genuine Endress+Hauser spare parts may be used.

• When ordering spare parts, please check the device designation on the nameplate.
Identical parts may only be used as replacements.

• Carry out repairs according to the instructions. Following a repair, the device must fulfill
the requirements of the individual tests specified for that device.

• A certified device may be converted to another certified device version by Endress
+Hauser Service only.

• All repairs and modifications must be documented.

12.1.3 Replacing sensor modules or main electronics

Once both sensor modules or the main electronics have been replaced, the sensor
module that is connected to the transmitter must be selected. To do this, follow these
steps:

1. Switch off the supply voltage

2. Replacing the sensor module or main electronics

3. Switch on the supply voltage.

4. Select sensor module LP or sensor module HP: Menu path: Expert → System →
