Product features .backup.book Page 4 Thursday, September 9, 2010 1:21 PM 1 PRODUCT FEATURES IFC 300 1.1 The signal converter with the highest performance The electromagnetic signal converter IFC 300 is designed to measure the flow velocity, conductivity, volume and mass flow of electrically conductive liquid media. The signal converter can be combined with any measuring sensor, making it very widely used. In terms of available housing versions, there is a compact variant, in which the signal converter is connected to the measuring sensor, as well as the field, wall-mounted and 19"...

.backup.book Page 7 Thursday, September 9, 2010 1:21 PM PRODUCT FEATURES 1 IFC 300 Remote design in various versions The signal converter in the wall-mounted housing is generally used when it is difficult to access the measuring point or when ambient conditions do not allow the use of the compact version. (signal converter in wall-mounted housing) The signal converter in the 19" rack-mounted housing is typically built into the central control room, away from the harsh ambient conditions that can be present at the measuring point. (signal converter in 19" rack-mounted housing (28 TE))...

.backup.book Page 8 Thursday, September 9, 2010 1:21 PM 1 PRODUCT FEATURES IFC 300 Diagnostics A part of the standard functionality is the comprehensive diagnosis, which consists of three different testing series. Testing the device function Checking the microcontroller, memory and outputs. Out-of-spec diagnosis Online and cyclical verification to determine whether the measuring device is still within its specifications regarding accuracy and linearity. Application testing The detection of potential problems such as gas bubbles, electrode deposits, low conductivity, liner damage, faulty...

.backup.book Page 9 Thursday, September 9, 2010 1:21 PM PRODUCT FEATURES 1 IFC 300 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 flow meter The signal voltage U is picked off by electrodes and is proportional to the mean flow velocity v and thus the flow...

.backup.book Page 12 Thursday, September 9, 2010 1:21 PM 2 TECHNICAL DATA IFC 300 Operating conditions Temperature Process temperature Refer to technical data for the measuring sensor. Ambient temperature Depending on the version and combination of outputs. It is a good idea to protect the converter from external heat sources such as direct sunlight as higher temperatures reduce the life cycle of all electronic components. -40…+65°C / -40…+149°F Ambient temperatures below -25°C / -13°F, may affect the readability of the display. Storage temperature -50…+70°C / -58…+158°F Pressure Medium...
