1.4 Functional principle
The flowmeter operates in accordance with the float measuring
principle.
A metal cone is installed in the measuring unit H54, in which
a suitably formed float can move freely up and down.
The flowmeter is inserted into a vertical pipeline and the
medium flows through it from bottom to top.
The guided float adjusts itself so that the buoyancy force
A acting on it, the wave resistance W and its weight G are
in equilibrium (G = A + W).
An annular gap which depends on the flow rate results.
The height of the float in the measuring unit, which depends
on the flow, is transmitted by a magnetic coupling and
displayed on a scale. Strong magnetic fields can lead to
deviations in the measured value.
The installation of several instruments in immediate vicinity to
each other does not cause notable influences.
5 H54 Installation and operating instructions
2 Installation and Start-up
2.1 Protection during shipment
The sensing arm and cam plate are secured by a rubber band.
2.2 Prerequisite for the installation
The operating pressure of the plant may not exceed the value indicated on the rating plate.
Ensure that the parts coming into contact with the medium are compatible with the material. (For the list
of the materials please refer to the chapter on the materials of the instrument designs.)
The ambient and medium temperatures may not exceed certain maximum values.
The variable area flowmeter has to be installed vertically (float measuring principle - flow direction from
bottom to top).
In order to prevent distortions the connecting flanges have to face each other axially and in parallel.
2.3 Preparation of the pipeline
The pipeline is to be supported by suitable installation measures, so that vibrations at the pipeline are
prevented and axial stresses on the instrument are minimized.
A straight unimpeded inflow section of ≥ 5 x DN before the instrument and a straight
outflow section of ≥ 3 x DN behind the instrument are recommended.
Shutoff and control devices are to be positioned in the flow direction behind the measuring unit.
For installation recommendations please also refer to the Directive VDE/VDI 3513, Sheet 3.
2.4 Installation in the pipeline
The instrument may not be subjected to tensile or compressive stresses through the pipelines.
Immediately before carrying out the installation check whether the instrument is free of foreign particles.
Screws, bolts and seals (provided by customer) are to be selected in accordance with the pressure stage
of the connecting flange or the operating pressure.
The inside diameter of the flange deviates from the standard dimensions.
Flange seal standard DIN 2690 (ASME B16.21) can be applied without any limitation.
Align the seals. Tighten the nuts with the tightening torques of the corresponding pressure stage.
2.5 Fastening torque
The flange bolts are to be tightened with the following maximum torques in case of measuring units with
PTFE liner or of measuring units with ceramic lining and PTFE sealing surface:

6 H54 Installation and operating instructions
2.6 Magnetic filters
Magnetic filters are used when the medium contains particles which can be influenced magnetically. The
magnetic filter is to be installed in the flow direction before the flowmeter. Magnetic bars are positioned
helically in the filter so that an optimal efficiency at a low pressure loss is achieved. All the magnets are
coated individually with PTFE to protect against corrosion. Two models are available:
Type F Type FS
Fitting part with flange Fitting part without flange
Overall length 100 mm Overall length 50 mm
Materials 1.4571 (316 Ti)
2.7 Observance of the IP degree (NEMA Type) of protection
The following instructions are to be observed in order to observe the IP degree (Nema Type) of electrical
built-in parts.
- After the connecting cable has been introduced, tighten the outlet nut.
- All the cable glands which are not used remain closed with blanking plugs.
- Do not kink lines directly at the cable gland.
- Provide a drain bend
- The feed lines may not be subjected to mechanical strains. Refer to the description
of the electrical supplementary components for this device.
Cable glands / screwed glands: PG11 - line diameter 8 to 10mm
2.8 Start-up
A minimum operating pressure (pre-pressure) is required to operate the instrument.
Medium Pressure loss : Operating pressure
Liquids 1 : 2
Gases (without damping) 1 : 5
Gases (with damping) 1 : 2
For the pressure losses please refer to the flow tables
2.9 Measurement of liquids
Vent the pipeline during starting-up in order to avoid liquid beats.
Open valves slowly!
2.10 Measurement of gases
Pulsations of the medium are to be kept away from the instrument.
In case of gases increase the operating pressure slowly.
The flow is to be varied by means of adjusting valves, so that the float is not subjected to blows
(e.g. through solenoid valves) thus ensuring that damage to the measuring unit cannot occur.
Instruments for measuring the flow rate of gases can be equipped with a gas damping, in order to avoid
possible compression vibrations of the float.
If vibrations nevertheless occur at the float, these can be eliminated by installing a throttle valve or a
suitable aperture hole (on request) behind the instrument.
A float damping is recommended for gas measurement.

10 Electrical signal output ESK3-PA
10.1 Bus cable
The statements of the FISCO model only apply if the bus cable used fullfills the following specifications:
R´ = 15...150 Ohm/km
L´ = 0.4...1 mH/km
C´ = 80...200 nF/km.
10.2 Shielding and grounding
In order to ensure optimum electromagnetic compatibility of systems it is very important that the system
components, and in particular the bus cables which connect the components, are shielded and that
these shields form an electrically unbroken envelope as far as possible.
10.3 PROFIBUS-PA connection
For the connection of the bus cable refer to the adjacent figure.
Connect the cable conductors to D and D- (polarity reversal
does not have any influence). The cable shield should be connected
with minimum length to the functional grounding FE.

11 Maintenance
The flowmeter is also to be inspected for soiling, corrosive erosion and mechanical wear or damage to the
measuring tube and the display in the context of the routine operational maintenance of the installation and the
pipelines. We recommend at least annual inspections. In order to clean the instrument remove it from the
pipeline.
Note
Pressurized lines have to be relieved before the measuring unit is removed.
Corresponding safety precautions with regard to residual liquids in the measuring unit in case of instruments
which are used to measure aggressive media.
New seals must always be used when remounting the measuring unit in the pipeline.
Electrostatic charges are to be avoided when the surfaces (e.g. viewing window) are cleaned!
Information on returning instruments
Your instrument has been manufactured carefully
and tested several times. If installed and operated in
accordance with these instructions your instrument
will rarely present any problems. Should you
nevertheless need to return an instrument for
checking or repair, please pay strict attention to the
following points:
Due to statutory regulations concerning protection
of the environment and safeguarding the health and
safety of our personnel, KROHNE may only handle,
test and repair returned instruments that have been
in contact with liquids if it is possible to do so
without risk to personnel and environment.
This means that KROHNE can only service your
device if it is accompanied by a certificate in line
with the following model confirming that the device
is safe to handle.
If the instrument has been operated with toxic,
caustic, flammable or water-endangering liquids,
you are kindly requested:
- To check and ensure, if necessary by rinsing
or neutralizing, that all the cavities in
the instrument are free from such dangerous
substances. (Directions on how you can find out
whether the primary head has to
be opened and flushed out and neutralized
are obtainable from KROHNE on request.)
- To enclose a certificate with the device confirming
that the device is safe to handle and
stating the liquid used.
KROHNE regret that we cannot service your device
unless it is accompanied by such a certificate and
thank you for your understanding.
