System description

Electromagnetic flowmeters are precision instruments designed for linear flow measurement of liquid products

The process liquids must be electrically conductive:, ≥ 5 µS/cm (for cold demineralized water ≥ 20 µS/cm).

The full-scale range Q

can be set as a function of the meter size: flow velocity of 0.3 - 12 m/s

100%

or 1 - 40 ft/s (s. Section 10.4.).

Product liability and warranty

The electromagnetic flowmeters are designed solely for measuring the volumetric flowrate of electrically conductive, liquid process products.

These flowmeters are available for use in hazardous areas. Special regulations apply in this case, which are given in the special EEx directions.

Responsibility as to suitability and intended use of these electromagnetic flowmeters rests solelywith the operator.

1 Electrical connection: power supply

1.1 Location and important installation notes ……………………. PLEASE NOTE !

• Electrical connection in accordance with VDE 0100 ”Regulations for the erection of power

installations with nominal voltages up to 1000 V” or equivalent national regulations.

• Do not cross or loop cables inside the terminal compartment.

• Use separate wiring (PG screwed cable entries) for power supply, field current lines, signal

lines, outputs and inputs.

• Hazardous areas are subject to special regulations, see Section 6.1 and special installation

instructions for hazardous-duty versions.

• Do not expose signal converter and switchgear cabinets with built-in converters to direct

sunlight. Install a sunshade if necessary.

• Signal converters installed in switchgear cabinets require adequate cooling (e.g. by fans

or heat exchangers).

• Do not expose signal converters to intense vibration.

• Keep the distance between the flow sensor and signal converter as small as possible, for

empty pipe detection (EPD) ≤ 20 m / ≤ 66 ft. Observe maximum lengths of signal and field current lines (see Section 1.3.4).

• Use KROHNE signal line A (type DS, standard) or signal line B (type BTS, bootstrap,

optional), standard length 10 m (33 ft).

• Generally use bootstrap signal lines B (type BTS) for PROFIFLUX 5000 F and VARIFLUX

6000 F flow sensors sized at DN 2.5-15 and 1/10’’-1/2’’ and for contaminated liquids which

tend to form electrically insulating deposits.

• Always calibrate flow sensor and signal converter together. During installation particular care

should therefore be given to identical settings of flow sensor constant GK (see instrument nameplate of flow sensor). In case GK constants are not identical, the signal converter must be adjusted to the flow sensor GK (see Sections 4 and 8.5).

• Dimensions of signal converter see Section 10.3.

IMPORTANT!

For EEx versions, also pay regard to all directions included in Sect. 6.1 and 13.

Only the EEx flow sensor may be installed in the hazardous area. The EEx certified signal converter must be installed outside the hazardous area!

1.3 Electrical connection of flow sensors

1.3.1 General remarks on signal lines A and B and field current line C

Proper operation of the equipment is ensured when KROHNE signal lines A and B are used with foil screen and magnetic shield.

• Signal lines must be firmly installed.

• Shields are connected via stranded drain wires.

• Underwater or underground routing is possible.

• Insulating material flame-retardant to IEC 332.1 / VDE 0742.

• Low-halogen, unplasticized signal lines which remain flexible at low temperatures.

Signal line B (type BTS) with triple shielding (bootstrap line)

8 Outer sheath

The bootstrap technology always controls the individual shields (3) of the signal converter exactly to the voltage which is supplied to the signal conductors (5). As this prevents voltage differences between the individual shields (3) and signal conductors (5), no current flows via the line capacitances between 3 and 5. The line capacitance seems to become ”zero”.

This allows greater cable lengths in case the electric conductivity of the liquid to be measured is low.

2.7 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 flow. The figures displayed may have a preceding sign.

• Such factory setting of current and pulse outputs may lead to measuring errors, particularly

when volumes are metered and totalized.

• If e.g. 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, Section 5.3

- display Fct. 1.04, Section 5.5

- current output I Fct. 1.05, Section 5.6

- pulse output P Fct. 1.06, Section 5.7

• For special applications, such as pulsating flows, see Sections 6.5 to 6.10

• Before connecting to power, check that the instrument is correctly installed as described in

Sections 1 and 2.

• The flowmeter, flow sensor and signal converter are delivered ready for operation. All

operating data are set at the factory in accordance with your specifications. Please also refer to Section 2.7 ”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 setting described for Fct. 1.04.

• 2 light-emitting diodes (LED) in the ”diagnostics” field on the front panel of the signal

converter indicate the status of measurement.

The EC type examination certificate has been issued by the Physikalisch-Technische Bundesanstalt (PTB) under: PTB 02 ATEX 2163 X

6.1.2 Main safety features

Both generation of the intrinsically safe electrode circuit and also protection of the non-intrinsically safe field circuit by fusible links form integral parts of the IFC 110 F - EEx signal converter.

• Category / Zone

IFC 110 F - EEx signal converters are associated electrical apparatus required to be installed outside the hazardous area. The intrinsically safe electrode circuit is designed in Category 2 for use in Zone 1.

• Types of protection

The electrode circuit is designed in Intrinsic Safety EEx ib IIC type of protection. The non-intrinsically safe field circuit must be installed inside the hazardous area using a type of protection conforming to European Standard (e.g. Increased Safety "e"). Power supply and signal inputs / outputs are non-intrinsically safe.

• Field current fuse protection

The field circuit is fuse-protected in the signal converter IFC 110F – EEx by two fusible links on the FSV circuit board (TR5, 160 mA F).

• Safety-relevant type code

The following code is used for type designation:

IFC

6.1.3 Installation and electrical connection

Type IFC 110 F - EEx signal converters are type tested as associated electrical apparatus. They are installed outside the hazardous area. The PE/PA connection (housing) must have protective bonding with the potential of the hazardous area (PA).

Insulation ratings

The insulation of signal converters Type IFC 110 F - EEx is rated in conformity with VDE 0110-1, equivalent to IEC 664-1, and the following rated values have been taken into consideration:

• overvoltage category for the line circuit: III

• overvoltage category for the signal and measuring circuits: II

• insulation pollution degree: 2

Important, please note without fail!

• The buffer barrier for the intrinsically safe electrode circuit is an integral part of the

IFC 110 F - EEx signal converter and is safety galvanically isolated.

• The cable entry for the interconnecting cable of the intrinsically safe electrode circuit

is marked in light blue.

• The terminals of the intrinsically safe electrode circuit may only be connected to

intrinsically safe circuits, even if the device is operated in the non-hazardous area.

• Electrical connection between front panel and potential to ground to be made by

way of the fastening screws on the front panel. These must therefore always be properly tightened down (torque approx. 1.3 Nm).

Start-up

Check the following points before starting up:

• that the line voltage (power supply) agrees with the details given on the nameplate.

• that the nominal value of the fuse for field current protection agrees with the maximum

permissible nominal value specified for the flow sensor. Evidence shall be furnished of the intrinsic safety for the electrode circuit together with the safetyrelevant data of the interconnecting cable and of the flow sensor.

Operation

Operator control of the signal converter is permitted during operation. For this purpose, remove the cover of the electronic compartment. Definitely avoid ingress of dirt and moisture when the housing cover is open.

Preventive maintenance

The signal converter does not require any maintenance when used for the intended purpose. Within the scope of checks required to be carried out in hazardous areas to maintain systems in proper working order, visual inspection of the housing, cable entries and interconnecting cables for signs of damage should be carried out at regular intervals.

Maintenance

Maintenance work of a safety-relevant nature within the meaning of explosion protection may only be carried out by the manufacturer, his authorized representative or under the supervision of authorized inspectors.

6.6 Unstable display and outputs

Unstable displays and outputs may occur:

– with high amounts of solids, – with inhomogeneities, – with badly blended mixtures, – after constant chemical reactions in the process liquid or – in ALTOFLUX 4000 F flow sensors when the wrong electrode material is selected for the

process liquid, e.g. Hastelloy B2 for hydrochloric acid.

If the flow is pulsating because of the use of diaphragm or reciprocating pumps please refer to Section 6.5.

Resetting the signal converter, see Sections 4 and 5.

When changing the signal converter settings, the green LED (normal) and the red LED (error)

on the front panel of the signal converter start to flash rapidly and frequently. This indicates that the A/D converter range is frequently exceeded and that not all measured values are evaluated.

Change the following settings to allow the display ripple to be properly evaluated:

Select ”BARGRAPH” in Fct. 1.04 DISPLAY, subfunction ”DISP. FLOW” and select ”YES” in submenu ”DISP. MSG.”.

Press ↵ key 4 times to return to measuring mode.

The following displays are possible in measuring mode:

= A/D converter range exceeded

ADC

and

OVERFL. I, P

PLEASE NOTE:

After each of the following changes check if the display and outputs are unsteady in measuring mode. Do not proceed to the next step unless the display and outputs continue to be unsteady.

• Fct. 1.02 TIMECONST. – Set to ”ONLY I”; set to ”ALL” when pulse output is also unsteady. – Set time constant to approx. ”20 seconds”, check if display remains unsteady and correct if

necessary.

• Fct. 3.06 APPLICAT.

Change setting of subfunction ”FLOW” to ”PULSATING” on a trial basis.

When the green LED and red LED continue to flash, change the setting of subfunction ”ADC GAIN” to 30. Should the green LED and red LED continue to flash frequently, set value to 10.

• Fct. 3.02 FIELD FREQ.

Change the setting to 1/2 on a trial basis. If this has no significant effect, restore the last setting (usually 1/6).

Only recommended for PROFIFLUX 5000 F (DN 2.5-100 and 1/10-4 inch) and ALTOFLUX 4000 F (DN 10, 15, 50-100 and for other types and sizes please consult factory.

• Fct. 3.06 APPLICAT.

– Select ”YES” in subfunction ”SPEC. FILT.” to activate a special noise filter.

– Subfunction ”LIMIT VAL.” defines a window with a width (somewhere around the mean flow) equivalent to the value in PERCENT of the full-scale range Q (Fct. 3.02, subfunction ”FULL SCALE”).

This value must always be a lot smaller than the amplitude of the display ripple

(peak-to-peak).

Example:

The delay required for passing on major changes of flow to the display and outputs is defined in subfunction ”LIMIT CNT.”.

Set subfunction ”LIMIT CNT.” to 10 on a trial basis.

Should the measuring value leave the above window in one direction more than 10 times, this window is temporarily rendered inactive.

Display and outputs follow major changes of flow with the appropriate speed.

This setting provides an additional dead time for display and outputs:

Dead time = LIMIT CNT. x duration of measuring cycle

Duration of measuring cycle = approx. 60 ms (for magnetic field frequency = 1/6 ´ line frequency, see Section 3.02, subfunction ”FIELD FREQ.”).

A ”10” set in subfunction ”LIMIT CNT.” results in a dead time of approx. 600 milliseconds.

By changing the subfunctions ”LIMIT VAL.”, ”LIMIT CNT.” and ”TIMECONST.”

(Fct. 1.02) on a trial basis, a setting can normally be found which ensures

that the display and outputs are sufficiently stable.

Each of the steps described above must be followed by a check

of the ripple of display and outputs in measuring mode.

6.9 Empty pipe detection EPD

The signal converter is equipped as standard with an EPD (Empty Pipe Detection) which only needs to be activated as and when required.

To ensure proper functioning, the following requirements need to be met:

Type of signal cable

A = Type DS B = Type BTS

Settings for empty pipe detection (EPD)

• Fct. 3.06 APPLICATION • EMPTY PIPE • YES (switched on) • NO (switched off)

The calibration mode must be run through during initial start-up!

• If“YES“ selected, the impedances for EMPTY and FULL PIPE need to be determined.

• Select subfunction VALUE FULL and CALIB. YES (determine impedance for “full pipe“)

WAIT (approx. 20 s)

• Select subfunction VALUE EMPTY and CALIB. YES (determine impedance for “empty pipe“)

WAIT (approx. 20 s)

• Store values after completion of calibration for “Full” and “Empty” values; quit operator control

after the second calibration.

When the electrodes are not wetted (= empty pipe), typically a response time of approx. 20 seconds is required before “empty pipe“ is indicated. In this time undefined display values and output signals are possible.

Functional description

A high-resistance AC voltage is applied to the electrodes. The process liquid in the measuring tube forms a voltage divider together with the internal resistance of the circuit. The voltage ratio is measured and weighted (see figure on right). Impedance and length of electrode cable will also affect the result.

The result is a numerical value proportional to the impedance at the input. The switching point of the Empty Pipe Detector is defined when the system is calibrated for “full pipe“ and “empty pipe“(at approx. 2/3 of the range between the two calibration points). In order to function properly there must be a difference of at least “10“ between the two calibration points. In operation, the display indicates in the range between 0 and 150 (non-dimensional). The value for “FULL PIPE“ must be lower than that for “EMPTY PIPE“.

Always switch off the power supply before opening the housing.

Required measuring instruments and tools

• Ohmmeter with at least 6 V measuring voltage range

• or AC voltage/resistance bridge

• Note:

accurate measurements in the electrode area can only be obtained with an AC voltage/resistance bridge. The measured resistance also heavily depends on the electrical conductivity of the process liquid.

Preparations

• Switch off the power supply.

• Remove the cover from the terminal compartment (remove 2 screws).

• Pull out the two plug-in terminals SC (5-pin, signal line) and FP (4-pin, field current supply

line), see illustration in Section 8.1.

• Fill the measuring tube of the flowmeter completely with process liquid.

• Please note:

the following measurements must only be carried out for plug-in terminals which are occupied (used).

Sect. 11 Part D Technical Data, Measuring Principle and Block Diagram

11 Measuring principle

The flowmeter is designed for electrically conductive fluids.

Measurement is based on Faraday’s law of induction, according to which a voltage is induced in an electrically conductive body which passes through a magnetic field. The following expression is applicable to the voltage:

U = K × B × v × D

K an instrument constant B magnetic field strength v mean velocity D pipe diameter

Inside the electromagnetic flowmeter, the fluid passes through a magnetic field applied perpendicular to the direction of flow. An electric voltage is induced by the movement of the fluid (which must have a minimum electrical conductivity). This is proportional to the mean flow velocity and thus to the volume of flow. The induced voltage signal is picked up by two electrodes which are in conductive contact with the fluid and is transmitted to a signal converter for a standardized output signal.

This method of measurement offers the following advantages:

1) No pressure loss through pipe constriction or protruding parts.

2) Since the magnetic field passes through the entire flow area, the signal represents a mean value over the pipe cross-section; therefore, only relatively short straight inlet pipes 5 x DN from the electrode axis are required upstream of the flow sensor.

3) Only the pipe liner and the electrodes are in contact with the fluid.

4) Already the original signal produced is an electrical voltage which is an exact linear function of the mean flow velocity.

5) Measurement is independent of the flow profile and other properties of the fluid.

The magnetic field of the flow sensor is generated by a square wave current fed from signal converter to the field coils. This field current alternates between positive and negative values. Alternate positive and negative flowrate-proportional signal voltages are generated at the same frequency by the effect of the magnetic field, which is proportional to the current. The positive and negative voltages at the flow sensor electrodes are subtracted from one another in the signal converter. Subtraction always takes place when the field current has reached its stationary value, so that constant interference voltages or external or fault voltages changing slowly in relation to the measuring cycle are suppressed. Power line interference voltages coupled in the flow sensor or in the connecting cables are similarly suppressed.
