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

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.

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.

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

Measuring principle and function of the system 11

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.:

xB xv x

U = K

where: U = induced voltage K = an instrument constant B = magnetic field strength v = mean velocity D = pipe diameter

Thus the induced voltage is proportional to the mean flow velocity, when the field strength is constant.

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 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

DN from the electrode axis are required upstream of the primary head.

3. Only the tube 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 primary head is generated by a square wave current fed from the 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 primary head 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 primary head or in the connecting cables are similarly suppressed.
