System description
The IFM 4110 PF electromagnetic flowmeters are precision instruments designed for the linear flow measurement of electrically conductive liquids, pastes and slurries with a minimum conductivity of 50 µS/cm (µmho/cm). The combination of a magnetic inductive flowmeter and a capacitive height measuring system stands for precise flow measurement in both fully and partly filled pipe lines. The filling degree must be at least 10 percent of the inner diameter.

7.30830.32.006
Part A System installation and start-up
1 Installation of the primary head
1.1 Selecting the installation location
1. Location and position as required, but electrode axis must be approximately horizontal. Max. deviation ± 2°.
2. Slope of measuring section, primary head with in- and outlet sections, is allowed to have maximum deviation of
±1% compared to horizontal.
3. Flow direction +/-, arrow on primary head must point in direction of flow.
4. Bolts and nuts: to install, make sure there is sufficient room next to the pipe flanges.
5. Vibration: support the pipeline on both sides of the flowmeter.
6. Use adapter pipes to permit axial shifting of counter flanges to facilitate installation.
7. Straight inlet run minimum of 5 x DN and outlet run minimum of 3 x DN (DN = meter size), measured from the
electrode axis. These are minimum values! Please take precautions to make sure that the flow profile inside the tube is axially symmetric. If this is not the case, the inlet and/or outlet sections have to be increased. Also, take precautions to minimize the amount of air bubbles in the fluid, i.e. caused by falling water in front of the primary head. Increase the inlet section if air can not be avoided.
8. Vortex or corkscrew flow: increase inlet and outlet sections or install flow straighteners.
9. Strong electromagnetic fields and large “iron masses”: avoid in vicinity of flowmeter.
10. Zero setting is automatic in flowmeters with pulsed DC field. Electrode contamination does therefore not cause any
zero drift. For most applications it is convenient and customary to check the zero by shutting off the flow. Shutoff valves should
therefore be provided upstream and/or downstream of the primary head unless the pipe configuration already rules out the possibility of the primary head being drained of fluid. For zero check see section 7.1.
12 Mixing different fluid products. Install flowmeter upstream of mixing point or at an adequate distance downstream,
minimum 30 x DN (DN = meter size), otherwise output/display may be unsteady.
13 Ambient temperature < 60 °°C / 140 °°F
Refer to sect. 10.1 for process temperature and pressure limits due to material used for measuring section/liner. When the primary head has to be installed in direct sunlight, please install a sunshade if necessary.
14 Long pipelines. Always install control and shutoff valves downstream of flowmeter (vacuum!). 15 Pumps. Never install flowmeter on pump suction side (vacuum!). 16 Service opening. It is strongly advised to construct some kind of service opening at the top of the connecting pipeline,
just before or just after the Tidalflux. In this way it is possible to see the flow, which can be helpful if problems occur. Also, it can be helpful to clean the liner if this gets polluted.
1.2 Grounding rings
Required in conjunction with electrically non-conductive pipes, i.e. synthetic, internally coated or concrete pipes. Especially
for the level measurement system special grounding rings have to be used. These rings have a cylindrical part that must go into the connected pipelines. Therefore the inner diameter of the pipeline must be known so the grounding rings can be made in a way they just fit in the pipeline. This is very important to keep a good flow profile of the fluid with as less disturbances as possible.
Grounding rings form a conductive connection with the fluid in order to get a low-impedance connection
Material CrNi steel 1.4571 or SS 316 Ti-AISI, others on request.
For grounding and connection of the grounding rings, refer to sect. 1.4.

1.5 Electrical connections of primary head
1.5.1 Connection to power Electrical connection in conformity with VDE 0100 / EN 61010-1
“Regulations governing heavy-current installations with rated voltages up to 1000 V” or equivalent national standard.
The electronics unit on top of the primary head needs a power supply of 115/230 V 48-63 Hz (14 VA), other voltages are available as an option. Please observe the information given on the nameplate of the primary head or in the terminal box about voltage and frequency. Please see also connection diagram in sect. 1.5.6.
1.5.2 Data interface between primary head and signal converter
Data cable: 3 x 1,5 mm2, shielded, for example Liycy, standard 10 meter included. For information about the connection, see the connection diagram in sect. 1.5.6. Special attention should be given to the PG9 cable gland, which is necessary to guarantee a faultless operation of data transfer between the signal converter and the primary head. The shielding of the data cable should therefore be connected to the housing by means of the two metal rings behind the rubber part in the gland. The shielding must be put between the two metal rings in a way that the shielding makes contact with the metal rings all around the cable. See also following figure:
1.5.3 Electrode cable General information to signal cables type DS and type BTS
General
Krohne signal cables types DS and BTS with foil and magnetic shields will ensure faultless system operation.
The signal cable must be a rigid installation. Cables must be secured so they do not move, or must be run in conduit.
No separate installation of signal and field power supply cables required - can be run in same conduit along with other signal
and field power cables. Do not run in same conduit with power cables for other devices.
Shields are connected via stranded drain wires.
Suitable for under water and underground installations.
Insulating material flame-retardant to IEC 332.1/VDE 0472
Low in halogen and unplasticized.
Flexible at low temperatures.
For connection of the cable, see the connection diagram in sect. 1.5.6.

Bootstrap signal cable type BTS
The signal converter automatically controls the individual shields (3) to exactly the same voltage as that applied to the signal wires (5). Since the voltage difference between signal wires (5) and individual shields (3) is virtually zero, there is no flow of current via the line capacitance 3+5; thus, line capacitance is apparently zero. Much longer cable lengths are then permitted for fluids with low electrical conductivity levels. 1 Dummy glider wire 2 Insulation 3 Special foil, 1st shield 4 Insulation 5 Stranded wire 0.5 mm2 (20 AWG) 6 Stranded drain wire, 1st shield, 0.5 mm2 (20 AWG) 7 Special foil, 2nd shield 8 Stranded drain wire, 2nd shield, 1.5 mm2 (14 AWG) 9 Insulation 10 Mu-metal foil, 3rd shield 11 Stranded drain wire, 3rd shield, 0.5 mm2 (20 AWG) 12 Outer sheath

1.5.4 Field current cable
The cross-section of the field current cable (standard not included) is dependent on the length that is required:
length Cross-section
0 – 150 m (0 – 500 ft) 2 x 0.75 mm2 Cu (2 x 18 AWG)
150-300 m (500 – 1000 ft) 2 x 1.5 mm2 Cu (2 x 14 AWG)
300 – 600 m (1000 – 2000 ft) 4 x 1.5 mm2 Cu (4 x 14 AWG)
1.5.5 Cable lengths: max. allowed distance between primary head and signal converter
Determining the maximum permissible distance between primary head and signal converter
1. The length of signal cable is dependent on the electric conductivity of the liquid product and of the type of cable used.
For BTS cable (optional) the maximum length is 600 m, independent of the conductivity. For DS cable (standard) the maximum length is as followes:
electr. conductivity
γ [µS/cm]
max. length
[m]
50 120 100 200 200 400 400 600
2. The length of field current cable is determined by the cable cross-section AF, see sect. 1.5.4.
3. The length of the data interface cable must not exceed 600 m.
4. The shortest cable length obtained either according to Point 1, 2 or 3 is the maximum permissible distance between
primary head and signal converter!

2.5.7 Standard factory settings
All operating data are set at the factory in accordance with the specifications contained in the order. If no specifications are made in the order, instruments will be delivered with the standard parameters and functions indicated in the table below. To facilitate the start-up of the instrument, current and pulse outputs are set to handle measurements in “two flow directions” so that the current flow rates and volumes are displayed and/or counted independent of the direction of the flow. The figures displayed may have a preceding sign. Such factory settings of current and pulse outputs may lead to measuring errors, particularly when volumes are metered and totalized, for example if pumps are switched off and “backflows” occur which are not within the low-flow cutoff (SMU) range, or if separate displays and counts are required for both flow directions. To avoid faulty measurements, it may therefore be necessary to change the setting of the following functions:
- SMU low-flow cutoff Fct. 1.03.
- display Fct. 1.04.
- current output I Fct. 1.05.
- pulse output P Fct. 1.06.

3 Start-up
Before connecting to power, check that the instrument is correctly installed as described in Sections 1 and 2.
The flowmeter (primary head and signal converter) is delivered ready for operation. All operating data are set at the factory
in accordance with your specifications.
Please also refer to sect. 2.5.7 “Standard factory settings”.
Switch on the power supply. The flowmeter immediately begins to measure the flow.
When the power supply is switched on, the display successively shows START UP and READY. Then the current flow
rate and/or the current totalizer count are displayed. Displays are either steady or cyclic depending on the settings described for Fct. 1.04.
PLEASE NOTE ! (If “YES” is entered in self check function 3.07)
When powered, the signal converter checks the current output by performing a short test with three different currents. To prevent false alarm, controllers or alarm functions should not be activated before the instrument is switched on.
2 light-emitting diodes (LED) in the “diagnostics” field on the front panel of the signal converter indicate the status of
measurement.
LED displays Status of measurement
Green “normal” LED is flashing Green “normal” LED and red “error” LED are flashing alternately Red “error” LED is flashing
