It has a very long battery life of up to 15 years, making it especially suitable for applications where no power connection is available. The WATERFLUX 3070 has been designed for custody transfer applications. It meets the requirements of the OIML R49 and can be verified according to MI-001 for DN25...300. The strength of the WATERFLUX lies in its unique flow sensor construction with a rectangular cross section. The coils are arranged so that a strong, homogeneous magnetic field is formed 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 and allows for no in- and outlet sections. t0 OO OO 1� Unique flow sensor design with rectangular cross-section 2� Highly resistant Rilsan®coating 3� Built-in reference electrode 04/2010-4000663102-TD WATERFLUX 3070 R02 en www.krohne.com 3 p PRODUCT FEATURES WATERFLUX Highlights • Low inaccuracy of±0.2% of measuring value + 0.5 mm/s • Suitable for custody transfer according to OIML R49 and MI-001 • Excellent performance in low flow conditions • Bi-directional measurement • No in- and outlet conditions (0 DN and 0 DN) • Low energy consumption and self providing energy by internal batteries for up to 15 years • Rilsan®polymer coating. • Buriable sensor (IP 68), installation in chambers is not necessary • Maintenance free operation, no moving parts, no wear and obstruction free • Optional battery powered data Logger/GSM module for remote data transfer • Very attractive cost of ownership • No grounding rings due to integrated reference electrode Industries • Dewatering • District metering • Irrigation • Revenue metering • Water abstraction Applications • Measurement of raw water, potable water, irrigation water • Well chambers • Monitoring of distribution networks • Pipeline leak detection • Measuring of water consumption 4 www.krohne.com 04/2010-4000663102-TD WATERFLUX 3070 R02 en PRODUCT FEATURES 0 1 .2 Options ,��• Remote version r� The WATERFLUX is also available in a remote field version with buriable IP 68 sensor as WATERFLUX 3070 F. 1 WATERFLUX as flowmeter opWhere mains power is available, the WATERFLUX sensor can be combined with the economical IFC 100 signal converter or the fully featured IFC 300 signal converter. GSM and data logger module: KGA 42 There is an increased demand by water utilities for remote reading of water meters. They are often installed at remote locations in the drinking water distribution networks or sites difficult to reach such as metering manholes below the ground. For all these applications the KROHNE KGA 42 data Logger and GSM module offers an efficient wireless communication solution for the transmission of data. It fulfils most customer requirements as it is easy to install, waterproof (IP 68), has a built-in dedicated antenna and operates on batteries. Connected with WATERFLUX 3070, KGA 42 sends out SMS reports on a daily basis or direct SMS alerts to maintenance personnel. 04/2010-4000663102-TD WATERFLUX 3070 R02 en www.krohne.com 5 H PRODUCT FEATURES WATERFLUX 1 .3 Measuring principle An electrically conductive fluid flows inside an electrically insulating 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 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.

WATERFLUX 3070 has a certificate of compliance with OIML R49, issued by NMi. The OIML R49 recommendation sets out the conditions to which water meters shall comply to meet the requirements of the services of legal metrology in countries where these instruments are subject to state controls. The measuring range of the water meter is determined by Q3 (nominal flow rate) and "R" (ratio). The WATERFLUX 3070 meets the requirements for water meters of accuracy class 1 and 2. For accuracy class 1, the maximum permissible error for water meters is±1%for the upper flow rate zone and ±3% for the lower flow rate zones. For accuracy class 2, the maximum permissible error for water meters is±2%for the upper flow rate zone and ±5% for the lower flow rate zones.
