2 Basic safety instructions
2.1 Requirements for the personnel
The personnel must fulfill the following requirements for its tasks:
‣Trained, qualified specialists must have a relevant qualification for this specific function
and task
‣Are authorized by the plant owner/operator
‣Are familiar with federal/national regulations
‣Before beginning work, the specialist staff must have read and understood the instructions
in the Operating Instructions and supplementary documentation as well as in the
certificates (depending on the application)
‣Following instructions and basic conditions
2.2 Designated use
Application and measured materials
The measuring device described in these Operating Instructions is intended only for level and
interface measurement of liquids. Depending on the version ordered the device can also
measure potentially explosive, flammable, poisonous and oxidizing materials.
Observing the limit values specified in the "Technical data" and listed in the Operating
Instructions and supplementary documentation, the measuring device may be used for the
following measurements only:
‣Measured process variable: Level and/or interface
‣Calculated process variable: Volume oder mass in arbitrarily shaped vessels (calculated
from the level by the linearization functionality)
To ensure that the measuring device remains in proper condition for the operation time:
‣Use the measuring device only for measured materials against which the process-wetted
materials are adequately resistant.
‣Observe the limit values in "Technical data".
Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated use.
Verification for borderline cases:
‣For special measured materials and cleaning agents, Endress+Hauser is glad to provide
assistance in verifying the corrosion resistance of wetted materials, but does not accept any
warranty or liability.
Residual risk
The electronics housing and its built-in components such as display module, main electronics
module and I/O electronics module may heat to 80 °C (176 °F) during operation through heat
transfer from the process as well as power dissipation within the electronics. During operation
the sensor may assume a temperature near the temperature of the measured material.
Danger of burns due to heated surfaces!
‣For high process temperatures: Install protection against contact in order to prevent burns.

5.1 Storage conditions
• Permitted storage temperature: –40 to +80 °C (–40 to +176 °F)
• Use the original packaging.
5.2 Transport product to the measuring point
฀WARNING
Housing or probe may be damaged or break away.
Risk of injury!
‣Transport the measuring device to the measuring point in its original packaging or at the
process connection.
‣Do not fasten lifting devices (hoisting slings, lifting eyes etc.) at the housing or the probe
but at the process connection. Take into account the mass center of the device in order to
avoid unintended tilting.
‣Comply with the safety instructions, transport conditions for devices over 18kg (39.6lbs).
A0013920
NOTICE
Shipping lock for FMP5x with coax probe
‣For FMP5x with coax probe the coax tube is not fixed permanently to the electronics
housing. For shipping and transport it is secured with two cable ties. In order to prevent the
spacer at the probe rod from moving along the probe, these cable ties must not be loosened
when transporting and mounting the device. They may only be undone directly before
screwing the device flange to the process connection.

• Pipe diameter: > 40 mm (1.6") for rod probes
• Rod probe installation can take place up to a diameter size of 150 mm (6 in). In the event of
larger diameters, a coax probe is recommended.
• Side disposals, holes or slits and welded joints that protrude up to approx. 5 mm (0.2")
inwards do not influence the measurement.
• The pipe may not exhibit any steps in diameter.
• The probe must be 100 mm longer than the lower disposal.

Mounting Levelflex FMP55 HART

• Within the measuring range, the probe must not get into contact with the pipe wall. If
necessary, use a center washer or centering star (see feature 610 of the product structure).
• Within the measuring range, the probe must not get into contact with the pipe wall. If
necessary, use a PFA centering star (see feature 610 of the product structure).
• Coax probes can always be applied if there is enough mounting space.
For bypasses with condensate formation (water) and a medium with low dielectric
constant (e.g. hydrocarbons):
In the course of time the bypass is filled with condensate up to the lower disposal and for
low levels the the level echo is superimposed by the condensate echo. Thus in this range
the condensate level is measured instead of the correct level. Only higher levels are
measured correctly. To prevent this, position the lower disposal 100 mm (4 in) below the
lowest level to be measured and apply a metallic centering disk at the height of the lower
edge of the lower disposal.
With heat insulated tanks the bypass should also be insulated in order to prevent
condensate formation.
For information on bypass solutions from Endress+Hauser please contact your Endress
+Hauser sales representative.
Non-metallic vessels
When mounting Levelflex in a non-metallic vessel, use a coax probe.
