Technical Datasheet Signal converter for electromagnetic flowmeters • Extended accuracy option • Diagnostics of device and application • Certified for use in hazardous areas The documentation is only complete when used in combination with the relevant documentation for the flow sensor.

1.1 The all-round solution The IFC 100 electromagnetic signal converter combines an attractive price with a wide range of 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....

Highlights For operation with a wide range of OPTIFLUX and WATERFLUX flow sensors For flow sensors over a diameter range from DN2.5 up to DN1200 Housing in aluminium with a polyester topcoat or in stainless steel (option) Tropicalized electronics to protect it from humidity (option) Available outputs: 4...20 mA current output, pulse/frequency output and status output/limit switch • Control input option • • • • • • HART® as standard • Power supply via 100…230 VAC (standard) or 24 VDC or 24 VAC/DC (optional) • Clearly readable values due to angle of the signal converter housing which prevents dirt...

1.2 Options and variants Compact or remote wall-mounted housing 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 flow sensor is difficult to access, or ambient temperature conditions or vibrations prevent a compact variant. (signal converter in wall-mounted...

Stainless steel housing (option) Whereas the standard housing material is aluminium with a polyester topcoat, the IFC 100 can 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...

1.3 Signal converter/flow sensor combination possibilities Flow sensor Flow sensor + signal converter IFC 100 Compact (0°/45° version) Remote wall-mounted housing 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 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...

Operating conditions Temperature Process temperature Refer to the technical data of the flow sensor. Ambient temperature -40…+65°C / -40…+149°F For compact devices is the maximum ambient temperature reduced depending on the flow sensor type and the process temperature. For details refer to the flow sensor manual. It is advised to protect the signal converter from external heat sources such as direct sunlight as higher temperatures reduce the life cycle of electronic components. Ambient temperatures below -25°C / -13°F may affect the readability of the display. Storage temperature Pressure Medium...
