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.

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.

Only part of the totalizer count is shown in the display because it is not possible to output a 14-digit number. Unit and format of the display are freely selectable, see Fct. 1.04, subfunction “DISP. TOTAL” and Sect. 5.4. This determines which part of the count is to be displayed. Display overflow and totalizer overflow are independent of one another.

6.7 HART®for IFC 090

HART®interface

The HART interface is a smart interface, in other words a communication signal superimposed on the current output. All functions and parameters can be accessed via this interface.

The following HART features are supported by the IFC 090 signal converter:

• point-to-point connection

• multidrop (up to 15 HART devices)

The burst mode is not normally used and is therefore not supported. Further information about HART is available from the HART Communication Foundation, of which Krohne is a member.

Electrical connection

HART connection active

to HART communicator or smart converter

HART connection passive

4 mA

to next HART device

power supply unit

to HART communicator or smart converter

Factory setting for the point-to-point mode with HART

• In Menu 1.05, the “FUNCT.I” parameter must be set to “1 DIR”. or “2 DIR.”.

• IMPORTANT: In Menu 1.05, the “RANGE I” parameter must be set to “4-20 mA”, or, in the case

of variable setting, the value for “I

” must be at least 4 mA.

• In Menu 3.09, the “COM1” parameter must be set to “HART” and the “ADDRESS” parameter to “0”.

• The current output may be operated in the active or passive mode.

Factor

y setting for the multidrop mode with HART

• In Menu 1.05, the “FUNCT.I” parameter must be set to “OFF”.

• In Menu 3.09, the “COM1“ parameter must be set to “HART” and the “ADDRESS” parameter to

a value of “1-15”. This address may only be set for one device in the HART multidrop network.

• IMPORTANT: the current output may only be operated in the passive mode.

6/5

Page 51

Minimum load im

pedance

A minimum load impedance of 250 Ωis required to enable the HART signals to be modulated on the current output. Series-connect an appropriate resistor if the devices located in the current output circuit should not attain this value. It will then be possible via the minimum load impedance e.g. to connect the HART communicator or smart converter in parallel without interrupting the current output. Please note that the load impedance should not exceed a maximum of 500

Ω

HART o

perating tools / DD

The IFC 090 can be operated either via its local operator interface or by means of the HART communicator or the CONFIG program. Both operating tools are available from KROHNE. Operator control by means of the HART communicator requires a device description (DD) which we can load for you into the communicator. We can, of course, also load the DDs of all manufacturers who have filed their DDs with the HART Communication Foundation. If you wish to use the IFC 090 in your operating tool, for example, please ask for the description of the HART command used so that you can address the complete IFC 090 functionality via HART.

In the near future we shall also be supporting the ASM tool from Rosemount and the SIPROM tool from Siemens.

Power supply units / isolation switchin

g amplifiers

You will need an appropriate power supply unit if the current output is to operate in the passive mode. Please ensure that this power supply unit is also suitable for HART communication. This applies equally to isolation switching amplifiers that are sometimes used in the active mode.

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.:

U = K xB xv xD 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 pipe 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 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.
