A magnetic coil located in the probe's measuring head generates a pulsed DC field perpendicular to the measuring head. This togetherwith the movement of the fluid induces a voltage proportional to the mean flow velocity. The voltage is picked up by two electrodes fitted to the front of the probe and forwarded to a signal converter, where it is converted into a measured flow speed. 01/2011 -4001208601-TD OPTIPROBE R01 en www.krohne.com 5 TECHNICAL DATA OPTIPROBE 2.1 Technical data • The following data is provided for general applications. lfyou require data that is more relevant to your specific application,please contact us oryour local representative. • Additional information(certificates, special tools, software,...]and complete product documentation can be downloaded free of charge from the website(Download Center].

Report damage to the carrier and to the local office of the manufacturer. Check the packing list to check if you received completely all that you ordered. Look at the device nameplate to ensure that the device is delivered according to your order. Check for the correct supply voltage printed on the nameplate. 3.2 Installation conditions 3.2.1 Inlet and outlet O O Figure 3-1:Recommended inlet and outlet sections (1) >_10 DN >_5DN 01/2011 -4001208601-TD OPTIPROBE R01 en www.krohne.com 9 p INSTALLATION 3.2.2 Mounting position 1771 03 40 s0 O O O — Figure 3-2:Mounting position 1� Flow profile must be fully developped. 22) Welding instructions:the electrodes must point to the side of the pipeline! 3Z Insert the OPTIPROBE perpendicular. 4� Insertion length>_25mm. 5� DN>_80mm. The OPTIPROBEis a sensor which measures flow speed atone point in the pipe. In case the flow speed has to be converted into a volume,please note that the measured value depends on the used diameter and the insertion length, because the OPTIPROBE decreases the inner surface of the pipe at the measuring section. The corrected GKl value for any other installation condition can be calculated as: 30 * insertion GKl = GKIcaL * (1 - 2 0.79 * DN All measures in mm GKI,,,is GKl on nameplate 3.2.3 T-section i t0 Figure 3-3:Distance after T-sections 1� >_30 DN 10 www.krohne.com 01/2011 -4001208601 -TD OPTIPROBE R01 en INSTALLATION 3.2.4 Vibration Figure 3-4:Avoid vibrations 3.2.5 Magnetic field Figure 3-5:Avoid magnetic fields 3.2.6 Bends Figure 3-6:Installation in bending pipes 01/2011-4001208601-TD OPTIPROBE R01 en www.krohne.com 11 p INSTALLATION Figure 3-7:Installation in bending pipes 3.2.7 Open discharge Figure 3-8:Installation before an open discharge 3.2.8 Control valve J Figure 3-9:Installation before control valve 12 www.krohne.com 01/2011-4001208601-TD OPTIPROBE R01 en INSTALLATION 3.2.9 Pump Figure 3-10:Installation after pump 3.2.10 Temperatures 02 10 1Q Process temperature © Ambient temperature Protect the device from direct sunlight.
