System description

Electromagnetic flowmeters with the IFC 010 signal converter are precision instruments designed for linear flow measurement of liquid products.

The process liquids must be electrically conductive: ³ 5 mS/cm (for cold demineralized water ³ 20 mS/cm).

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

DN 2.5.- 1000 / 01/10” - 40” Q100% = 0.010 - 34 000 m3/hr = 0.03 - 151 000 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 010 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.

CE / EMC / Standards / Approvals

Electromagnetic flowmeters with the IFC 010 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.

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 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 GKL is identical; refer to instrument nameplate for the primary head. If the GKL is not identical, set the signal converter to the GKL of the primary head.

Refer also to Sections 4.

Dimensions of signal converter; refer to Section 10.4.

1.1.3 Cable entries

Number of cable entries: 2 for the compact flowmeters

4 for the IFC 010 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 x lbf

2

Max. torques for PG 13.5 only: 3 Nm / 2.1 ft x lbf

3 Gasket

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.

1/1

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 classes III and II, respectively.

Safety isolation: the flowmeters (signal converters) must be provided with an isolating facility.

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.

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, 48 V AC), provide for protective separation (PELV) in conformity with VDE 0100 / VDE 0106 or IEC 364 / IEC 536, or equivalent national regulations.

The pulse and status outputs can be operated in the active or passive mode.

 

Active mode:

The current output is the internal voltage source,

 

 

connection of electronic totalizers (EC)

 

Passive mode:

External DC or AC voltage source required, connection of electronic (EC)

 

 

or electromechanical (EMC) totalizers

 

Digital pulse division, interpulse period is non-uniform. Therefore, if frequency meters or cycle counters are connected, allow for minimum counting interval:

3 Start-up

3.1Poweron and measurement

Before powering the system, please check that it has been correctly installed according to Sect. 1 and 2.

The flowmeter is delivered ready for operational use. All operating data have been factory set in accordance with your specifications.

Please refer to Sect. 3.2 “factory settings”.

Power the unit, and the flowmeter will immediately start process flow measurement.

Basic version, signal converter IFC 010 / B

A light emitting diode (LED) under the cover of the electronic section shows the measurement status.

LED flashing . . .

green: measurement correct, everything all right. green / red: momentary overdriving of outputs

and/or A/D converter.

red: fatal error, parameter error or hardware fault, please consult factory.

Refer to Sect. 6.1 for operator control of the “basic version”.

Display version, signal converter IFC 010 / D

When powered, the display shows in succession: START UP and READY.

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”.

3/1

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
