System description

Electromagnetic flowmeters with the IFC 090 signal converter 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 DN 2.5.- 1000 / 01/10” - 40” Q

can be set as a function of the meter size:

100%

= 0.010 - 34 000 m3/hr = 0.03 - 151 000 US Gal/min

100%

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 090 signal converter are designed solely for measuring the volumetric flowrate of electrically conductive, liquid process products.

Special codes and regulations apply to their use in hazardous areas and these are referred to in the special “Ex” Installation and Operating Instructions (supplied only with hazardous-duty equipment).

Responsibility as to suitability and intended use of these compact 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.

CE / EMV / Standards / Approvals

• Electro magnetic flowmeters with the IFC 090 signal converter meet the requirements of the EU-EMC Directives and bear the CE symbol.

• All factories and production sequences are ISO 9001 certified.

• Flowmeters are approved as hazardous-duty equipment to the harmonized European Standards and to Factory Mutual (FM). Further details are given in the “Ex” supplementary instructions provided only with hazardous-duty equipment.

Items included with supply

• Signal converter as ordered

• Installation and operating instructions

Part A System installation and start-up

1 Electrical connection: power supply

1.1 Location and important installation notes PLEASE NOTE !

• 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 (PG screwed conduit entries) for power supply,

field current cables, signal lines, outputs and inputs.

• Hazardous locations are subject to special regulations, see Section 6.1 and special installation instructions for hazardous-duty (”Ex”) versions.

• 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.

Onl

y for separate systems/signal converters (F 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 Sections 4 and 8.5.

• Dimensions of signal converter; refer to Section 10.2.

1/1

PLEASE NOTE !

Connection to power 1.2

• 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 classes III and II, respectively.

• Safet

y 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 I and II for power supply and electrical connection between primary head and signal converter: refer to Section 1.3.5.

• Note information on instrument nameplate: supply voltage and frequency.

• For measurement reasons, connect an FE functional ground conductor to the separate

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

• If connected to a functional extra-low voltage source (24 V AC / DC), provide for protective separation (PELV) in conformity with VDE 0100 / VDE 0106 or IEC 364 / IEC 536,

or equivalent national regulations.

This is followed by display of the current flow rate and/or the current totalizer count on either a continuous or alternating basis, depending on the setting under Fct. 1.04.

• Refer to Sect. 4 and 5 for operator control of the “display version”.

Factory settings 3.2

All operating data are factory set according to your order specifications. If you have not made any particular specifications at the time of ordering, the instruments will be

delivered with the standard parameters and functions listed in the Table below. To facilitate easy and rapid initial start-up, current output and pulse output are set to process flow

measurement in “2 flow directions”, so that the current flowrate is displayed and the volumetric flow counted independent of the flow direction. On instruments equipped with a display, measured values may possibly be shown with a “ – ” sign.

This factory setting for the current and pulse outputs may possibly lead to measuring errors, particularly in the case of volume flow counting:

for example, if pumps are switched off and a “backflow” occurs which is not within the range of the low-flow cutoff (SMU), or if separate displays and counts are required for both flow directions.

To avoid faulty measurements, therefore, it may be necessary to change the factory setting of some or all of the following functions: – low-flow cutoff SMU, Fct. 1.03, Sect. 5.3 – current output I, Fct. 1.05, Sect. 5.6 – pulse output P, Fct. 1.06, Sect. 5.7 – display (option), Fct. 1.04, Sect. 5.4

For special applications, for example “pulsating flow”, see Sect. 6. Instrument o

peration:

Display versions: IFC 090 _/ D, operation: refer to Sect. 4 and 5. Basic versions: IFC 090 _/ B, operation: refer to Sect. 6.2.
