independence The IFC 070 is a battery powered electromagnetic signal converter designed for use in combination with the WATERFLUX 3000 sensor. It is ideal for remote locations in the water industry where no power connection is available and provides certainty in case of power failure. The strengths of the WATERFLUX 3070 lies in its unique flow sensor construction with a rectangular and reduced cross section and its efficient coil construction. The coils provide a stronger and more homogenous magnetic field, leading to an improved signal to noise ratio.The measurement is therefore independent of the flow profile and measurements are very stable. This results in a very good low flow performance. Because of the unique WATERFLUX flow sensor design,whereby the mean flow velocity and flow profile are optimised within the rectangular and reduced cross section, the additional uncertainty for upstream disturbances is drastically reduced. The water meter can be installed directly after an elbow or reducer in the pipe without straight inlet or outlet lengths. A substantial reduction of inlet and outlet sections means smaller measurement pits. Another major benefit of the rectangular sensor construction is the very low power consumption of the signal converter. It has a long battery lifetime of up to 15 years with two internal batteries and 20 years with an external battery pack.

The functionality of the compact and the remote version is identical. 1 1 IP 68 (NEMA 6P)version for submersion The IFC 070 compact signal converter is available in an aluminium and in a polycarbonate housing. The signal converter in a polycarbonate housing is suitable for submersion in flooded measurement chambers and is protected to IP 68/ NEMA 6P. The 1 output cable has plug and play IP 68 KPONNE rated connectors. 1 07/2011-4000663103-TD WATERFLUX 3070 R03 en www.krohne.com 5 p PRODUCT FEATURES NOW"' 1 Internal and external battery pack The WATERFLUX 3070 can be operated using 1 or 2 lithium monocell batteries or an external battery pack. The meter reading is saved internally, which ensures that there is no loss of data when changing the batteries. The signal converter has a very low power consumption because of its rectangular sensor construction. • With two internal batteries it has a battery lifetime up to 15 years. 4 Maintenance free and buriable The flow sensor (IP 68) is submersible in flooded measurement chambers. ( � With its robust construction it can also be buried underground. This can be a major cost saving as it eliminates the need for building a measurement chamber. To protect the flow sensor a special coating can be ordered as an option. The remote version has a IP 68 stainless steel connection box. 6 www.krohne.com 07/2011-4000663103-TD WATERFLUX 3070 R03 en PRODUCT FEATURES 0 KGA 42 data logger and GSM module for remote reading The KGA 42 data logger and GSM module offers an efficient solution for remote reading of water meters and the transmission of data via wireless communication. The KGA 42 sends out SMS/GPRS reports on a daily basis or direct SMS/GPRS alerts to maintenance personnel. The module is easy to install,waterproof UP 68), has a built-in dedicated antenna and operates on batteries.

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 rate q. A signal converter is used to amplify the signal voltage, filter it and convert it into signals for totalising, recording and output processing.

Therefore it is usually recommended to fit a straight inlet length before and straigth outlet length after a water meter. As a result of the unique WATERFLUX flow sensor design,whereby the mean flow velocity and flow profile are optimised within the rectangular and reduced cross section, the additional uncertainty for upstream disturbances are drastically reduced. Therefore the requirements for straight length before and after a meter are reduced. The NMi has performed tests with various flow and swirl disturbers according to ISO 4064 and EN 14154. Based on these results the WATERFLUX 3070 has received a OIML R49 certificate • Diameter range DN25...300 • Accuracy class 1 and class 2 • Minimum straight inlet and outlet pipe length of 0 DN • Bi-directional flow • Any pipe orientation EC-type certificate according MID Annex MI-001 • Diameter range DN25...300 • Minimum straight inlet and outlet pipe length of 0 DN • Bi-directional flow • Any pipe orientation 20 www.krohne.com 07/2011 -4000663103-TD WATERFLUX 3070 R03 en TECHNICAL DATA 2.4 Vacuum load Diameter Minimum operating pressure absolute in mbar(abs) at process temperature [mm] 200C 400C 600C 800C Rilsan® DN25...300 0 0 0 0 Hard rubber DN350...600 500 500 600 600 Diameter Minimum operating pressure absolute in psia at process temperature [inch] 68OF 1040F 140OF 1760F Rilsan® 1...12" 0 0 0 0 Hard rubber 14...24" 7.3 7.3 8.7 8.7 07/2011-4000663103-TD WATERFLUX 3070 R03 en www.krohne.com 21 TECHNICAL DATA 2.5 Dimensions and weights Compact version in b a= 170 mm/6.7" aluminium housing (IP67) b= 132mm/5.2" a c= 140mm/5.5" Total height=H +a 9W0— H L Compact version in b a= 159 mm/6.3" ppoLycarbonate housing 1IP681 b= 161 mm/6.3" i a i Total height=H +a i L 0 o IN flow sensor b a=77 mm/3.1" b= 139mm/5.5" 1Q J a c= 106mm/4.2" Total height=H +a H - --- - L Remote version in b c b= 132 mm/5.2" aluminium housingP.
