System description

Electromagnetic flowmeters with the IFC 020 signal converter are precision instruments designed

for linear flow measurement of liquid products.

The process liquids must be electrically conductive: ≥5µS/cm

(for cold demineralized water ≥20 µS/cm).

The full-scale range Q100% can be set as a function of the meter size:

Q100% = 0.0060- 86 860 m3/hr = 0.03 - 156.672 US Gal/min

This is equivalent to a flow velocity of 0.3 - 12 m/s or 1 - 40 ft/s.

Product liability and warranty

The electromagnetic flowmeters with the IFC 020 signal converter are designed solely for

measuring the volumetric flowrate of electrically conductive, liquid process products.

These flowmeters are not certified for use in hazardous areas. Other flowmeter series are

available for such applications.

Responsibility as to suitability and intended use of these electromagnetic flowmeters rests solely

with the operator.

Improper installation and operation of the flowmeters (systems) may lead to loss of warranty.

In addition, the “General conditions of sale” forming the basis of the purchase contract are

applicable.

If flowmeters need to be returned to Krohne, please note the information given on the last-but-one

page of these Instructions. Krohne regrets that it cannot repair or check your flowmeter(s) unless

accompanied by the completed form sheet.

• Electromagnetic flowmeters with the IFC 020 signal converter meet the protection requirements

of Directive 89/336/EEC in conjunction with EN 50081-1 (1992) and EN 50082-2 (1995),

as well as Directives 73/23/EEC and 93/68/EEC in conjunction with EN 61010-1, and bear the

CE marking.

Installation and operating instructions IFC 020

1/1

Part A System installation and start-up

1 Electrical connection: power supply

1.1 Important installation notes PLEASE NOTE !

1.1.1 Location

• Electrical connection in accordance with VDE 0100 ”Regulations governing heavy-current

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

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

•Use separate cable entries (see below) for power supply, field current cables, signal lines,

outputs and inputs.

•Protect flowmeters or switchgear cabinets with built-in devices from direct sunlight.

Fit a sunshade if necessary.

•When installed in switchgear cabinets, signal converters must be adequately cooled,

e.g. use fans or heat exchangers.

•Do not expose signal converters to intense vibration.

1.1.2 Only for separate systems/signal converters (F- and E versions)

•Keep distance between primary head and signal converter as short as possible.

Refer to Sect. 1.3.4 for maximum permissible length of signal and field current cables.

•Use the supplied Krohne signal cable A (Type DS), standard length 10 m (33 ft).

•Always calibrate primary head and signal converter together. Therefore, when installing,

ensure primary constant GK is identical; refer to instrument nameplate for the primary

head. If the GK is not identical, set the signal converter to the GK of the primary head.

Refer also to Section 4.

• Dimensions of signal converter; refer to Section 10.4.

1.1.3 Cable entries (K- and F- versions)

Number of cable entries: 2 for the compact flowmeters

4for the seperate IFC 020 F signal converter

NOTE: Ensure gaskets are fitted correctly and maintain

the following max. torques!

1Max. torques for PG 13.5,

1/2“ NPT or 1/2“ PF adapters: 4 Nm / 2.8 ft xlbf

2Max. torques for PG 13.5 only: 3 Nm / 2.1 ft xlbf

3Gasket

A) PG 13.5 cable entries

These cable entries may only be used for flexible electrical cables if the relevant electrical

regulations so allow, e.g. National Electric Code (NEC).

Do not fix rigid metal conduits (IMC) or flexible plastic conduits to the PG 13.5 cable entries, refer

to “Point B/C” below (1/2” NPT or PF adapters).

B) 1/2“ NPT adapters C) 1/2“ PF adapters

For most North American systems the regulations require that electrical conductors be laid in

conduits, particularly where power voltages > 100 V AC are concerned.

In such cases, use the 1/2” NPT or 1/2” PF adapters to which flexible plastic conduits can be

screwed. Do not use rigid metal conduits (IMC)!

Lay conduits such that no moisture can penetrate into the converter housing.

Should there be risk of any condensation water forming, fill the cross-section of the conduit

around the cables at these adapters with a suitable sealing compound.

Connection to power 1.2

PLEASE NOTE !

•Rated values: The flowmeter housings protecting the electronic equipment from dust

and moisture must always be kept closed. The selected creepage distances and

clearances have been dimensioned in conformity with VDE 0110 and IEC 664 for

contamination category 2. Supply circuits and output circuits are designed to meet the

standards of overvoltage class II.

•Safety isolation: the flowmeters (signal converters) must be provided with an

isolating facility.

• Note information on instrument nameplate: supply voltage and frequency

•The PE protective ground conductor for the power supply must be connected to the

separate U-clamp terminal in the terminal compartment of the signal converter.

For exceptions (compact systems), refer to installation instructions for the primary head.

• Connection diagrams for electrical connection between primary head and

signal converter: refer to Section 1.3.5 and 1.3.6.

•If connected to a functional extra-low voltage source (24 V AC / DC, 48 V AC),

provide for protective separation (PELV) in conformity with VDE 0100 / VDE 0106 or

IEC 364 / IEC 536, or equivalent national regulations.

• Connection diagrams for power supply and electrical connection between primary

head and signal converter: refer to Section 1.3.6.

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.

1.3.2 Grounding of primary head

• All flowmeters must be properly grounded.

• The grounding conductor should not transmit any interference voltages.

• Do not ground any other electrical device together with this conductor.

• The primary head is connected to ground by means of an FE functional ground conductor.

• Special information on grounding various primary heads is contained in the separate

installation instructions for primary heads.

• These instructions also contain detailed descriptions on how to use grounding rings and

how to install primary heads in metal or plastic pipes or internally coated pipelines.
