PRODUCT FEATURESD 1.1 Solution for nuclear environments The AFC 030 electromagnetic flow converter is designed to measure flow velocity of electrically conductive liquids in radiation areas, for both safety as non-safety applications. The AFC 030 can be combined with two types of measuring sensors: POWERFLUX 4000 and POWERFLUX 5000. For maximum reliability and durability the AFC 030 does not contain any programmable electronic components (PEC). It features an adjustable flow range. The flow is indicated as a percentage of the maximum flow with the LED bar or with a 4 - 20 mA output. Figure...

1.3 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 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...

2.4 Measurement accuracy Every electromagnetic flowmeter is calibrated by direct volume comparison. The wet calibration validates the performance of the flowmeter under reference conditions against accuracy limits. The accuracy limits of electromagnetic flowmeters are typically the result of the combined effect of linearity, zero point stability and calibration uncertainty. Reference conditions Medium: water Temperature: +5...+35°C / +41...+95°F Operating pressure: 0.1...5 barg / 1.5...72.5 psig Inlet section: ≥ 5 DN Outlet section: ≥ 2 DN Figure 2-1: X [m/s] : flow velocity Y [%]:...
