Liquicap M FMI51, FMI52 (PFM) Safety instructions
Endress+Hauser 3
1 Safety instructions
1.1 Designated use
Liquicap M FMI51, FMI52 are compact, capacitance level transmitters for the continuous
measurement of liquids.
1.2 Installation, commissioning and operation
Liquicap M is designed to meet state-of-the-art safety regulations and complies with the applicable
requirements and EC Directives. If used improperly or other than intended, the device can,
however, be a source of application-related danger, e.g. product overflow as a result of incorrect
installation or configuration. For this reason, installation, electrical connection, commissioning,
operation and maintenance of the measuring system must only be carried out by trained technical
personnel authorized to perform such work by the owner-operator. The technical personnel must
have read and understood these Operating Instructions and must follow the instructions they
contain. The device may only be repaired or modified if expressly permitted in the Operating
Instructions.
1.3 Operational safety
When performing configuration, testing and maintenance work on the device, alternative
supervisory measures must be taken to guarantee the operational safety and process safety.
1.3.1 Ex area
When using the measuring system in Ex-areas, the appropriate national standards and regulations
have to be observed. Separate Ex documentation, which constitutes an integral part of this
documentation, is supplied with the device. The installation procedures, connection data and safety
instructions it contains must be observed.
• Make sure that the technical staff has adequate training.
• The special measuring and safety-related requirements for the measuring points must be
observed.

1.4 Notes on safety conventions and icons
To highlight safety-related or alternative processes, we have designed the following safety
instructions where every instruction is indicated by a corresponding pictogram.
Safety instructions
#Warning!
Draws attention to activities or procedures that can result in serious injuries to persons, a safety risk
or the destruction of the device if not carried out properly.
"Caution!
Draws attention to activities or procedures that can result in injuries to persons or the defective
operation of the device if not carried out properly.
!Note!
Draws attention to activities or procedures that have an indirect effect on operation, or can trigger an
unforeseen device reaction if not carried out properly.
Type of protection
0Explosion-protected equipment tested for type examination
If this sign can be found on the nameplate of the device, the device can be operated in hazardous
areas or non-hazardous areas in accordance with the approval
-Ex area
This symbol in the drawings in these Operating Instructions indicates Ex-areas. Devices located in
Ex-areas, or cables for such devices, must have appropriate explosion protection.
.Safe area (non-hazardous area)
This symbol in the drawings in these Operating Instructions indicates non-Ex areas. Devices in non-
hazardous areas must also be certified if connecting cables lead into hazardous areas.
Electrical symbols
%Direct current
A terminal to which direct voltage is applied or through which the direct current flows.
&Alternating current
A terminal to which alternating voltage (sine wave) is applied or through which the alternating
current flows.
)Ground connection
A grounded terminal which, from a user's point of view, is grounded via a grounding system.
*Protective earth connection
A terminal that has to be grounded before any other connections may be established.
+Equipotential connection
A connection that has to be connected to the grounding system of the plant. This can be a potential
matching line or a star grounding system, depending on national or company codes of practice.
Immunity to temperature change of the connecting cables
Means that the connecting cables have to withstand a temperature of 85 °C at least.

1.) Screw in the device
2. a) Loosen clamping screw until the housing rotates easily.
2. b) Align the housing.
2. c) Tighten clamping screw (< 1 Nm) until the housing can no longer be rotated.
3.2 Incoming acceptance, transport, storage
3.2.1 Incoming acceptance
Check whether the packaging or content is damaged.
Check that the goods delivered are complete and compare the scope of delivery against the
information on your order.
3.2.2 Storage
For storage and transportation, pack the device in such a way as to protect it reliably against impact.
The original packaging offers the best protection for this.
The permitted storage temperature is –50°C to +85°C.

3.3 Planning instructions
3.3.1 Installation
The Liquicap M FMI51 (rod probe) can be installed from above and from below.
The Liquicap M FMI52 (rope probe) can be installed vertically from above.
!Note!
• The probe may not come into contact with the container wall!
• Recommended distance from the container floor: ≥10 mm.
• Do not install probes in the area of the filling curtain!
• If using the probe in agitator tanks, make sure the probe is at a sufficient distance from the agita-
tor.
• Rod probes with a ground tube must be used in the event of severe lateral load.

3.3.2 Support with marine approval (GL)
Conductive or nonconductive support can be provided for fully insulated rod probes.
Partially insulated rod probes may only be supported with insulation at the uninsulated end of the
probe.
!Note!
Rod probes with a diameter of 10 mm and 16 mm have to be supported with a length ≥ 1 m (see
drawing).
L00-FMI5xxxx-06-05-xx-xx-077
Example for calculating distances:
Probe length L = 2000 mm.
L/4 = 500 mm
L/2 = 1000 mm
Measured from the end of the probe rod = 300 mm.
3.4 Measuring condition

• Measuring range L1 possible from the tip of
the probe to the process connection.
• Particularly suited for small containers.
• Use a ground tube for nonconductive
media.
Note!
When installing in a nozzle, use inactive
length (L3).
The 0 %, 100 % calibration can be inverted.

3.6 Installation examples
3.6.1 Rod probes
Conductive tanks (metal tanks)
If the process connection of the probe is insulated from the metal tank (e.g. using seal material), the
ground connection on the probe housing must be connected to the tank using a short line.
!Note!
• A fully insulated rod probe may be neither shortened nor extended.
• If the insulation of the probe rod is damaged, this results in an incorrect measurement result.
• These application examples show vertical installation for continuous level measurement.

3.6.3 Shortening the rope
!Note!
See Operating Instructions, rope shortening kit KA061F/00.
3.6.4 Tensioning weight with tension
The end of the probe needs to be secured if the probe would otherwise touch the silo wall or another
part in the tank. This is what the internal thread in the probe weight is intended for.
The bracing can be conductive or insulating to the tank wall.
To avoid too high a tensile load the rope should be loose or guyed with a spring. The maximum
tensile load may not exceed 200 Nm.
