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: ≥ 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 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 Onl

• 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

y for separate systems/signal converters (F versions)

NOTE: Ensure gaskets are fitted correctly and maintain

the following max. torques! 1 Max. torques for PG 13.5,

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

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.

• 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

3.1 Power-on 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

• A light emitting diode (LED) under the cover of the electronic section shows the

measurement status.

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
