1.1 The all-round solution

The IFC 100

IFC 100 electromagnetic signal converter combines an attractive price with a wide range of

IFC 100IFC 100 features and benefits including an excellent measuring accuracy. The signal converter is compatible with almost any flow sensor in the OPTIFLUX and WATERFLUX range.

The signal converter supplies the current required by two field coils to generate a magnetic field. It converts the flow proportional signal voltage into digital values and filters out electrical noise and interference signals. From the filtered signal, the flow velocity, the volume flow and the mass flow are calculated.

The IFC 100

IFC 100 signal converter provides a large variety of flowmeter and process diagnostic

IFC 100IFC 100 functions guaranteeing reliable measurements. Detection of deposits or coating on the electrodes, temperature and conductivity changes in the medium, gas bubbles or solids, and an empty pipe are good examples of process diagnostics functions.

The flow velocity and volume can be read from the display or in analogue form via the current output (4...20 mA) as well as by frequency, pulse and status outputs. Measuring values and

diagnostic information can be transmitted via the HART

1.2 Options and variants

Compact or remote wall-mounted housing

(signal converter in wall-mounted

aluminium housing)

PRODUCT FEATURES

For an optimal reading of the display, the compact

variant comes in a 0° and a 45° version. The signal converter can be rotated in 90°

increments to suit different installation positions.

The compact 0° version is designed for flowmeters in vertical pipelines, the compact 45° version for

horizontal installations.

The wall mounted signal converter can be installed remotely for locations where the sensor is difficult to access, or ambient temperature conditions or vibrations prevent a compact variant.

Variant for use in hazardous areas

(Compact version as 0° version)

The IFC 100 signal converter is available in a variant suitable for hazardous areas with approvals to ATEX, IECEx, FM, CSA and NEPSI.

PRODUCT FEATURES

Stainless steel housing (option)

(signal converter in wall-mounted

stainless steel housing)

IFC 100

Whereas the standard housing material is aluminium with a polyester topcoat, the IFC 100 optionally be ordered in a stainless steel housing.

The robust housing is suitable for many applications in the food and beverage industry. It is designed for environments where extreme chemicals or aggressive cleaning are used.

The housing is dual rated to IP67/69 protection category to resist wash down cleaning and no glass is used for the display window.

The mounting angle for the compact housing and the rounded edges in the wall-mount position prevent dirt and water from building up on the surface.

Diagnostics of device and application

OPTICHECK tool for on-site verification

The primary focus of a user for a flowmeter is that it delivers reliable measurements. To achieve this all our electromagnetic flowmeters are calibrated before leaving the factory.

In addition, the IFC 100 functions on the flow sensor, signal converter and process, integrated in the signal converter.

Potential problems including gas bubbles, solids, electrode corrosion, deposits on electrodes, conductivity changes, empty pipe can be detected by the diagnostics features.

The OPTICHECK provides an inline health check of the device under test by an external tool. When the tool is connected on site, it gathers measuring data to ensure that the flowmeter performs within 1% of its factory calibration.

IFC 100 provides a range diagnostic

IFC 100IFC 100

(Suitcase with OPTICHECK and all cables and

accesssories)

The baseline can be historic repair data from the factory or on-site test results after performing a full verification.

A hard copy of the verification report can be printed for every flowmeter. The verification data are digitally stored.

1.4 Measuring principle

An electrically conductive fluid flows inside an electrically insulated pipe through a magnetic field. This magnetic field is generated by a current, flowing through a pair of field coils. Inside of the fluid, a voltage U is generated: U = v * k * B * D

U = v * k * B * D

U = v * k * B * DU = v * k * B * D

in which: v = mean flow velocity k = factor correcting for geometry B = magnetic field strength D = inner diameter of flowmeter

The signal voltage U is picked off by electrodes and is proportional to the mean flow velocity v and thus the flow rate Q. A signal converter is used to amplify the signal voltage, filter it and convert it into signals for totalizing, recording and output processing.
