The coils provide a stronger and more homogeneous 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 3000 flow sensor design, whereby the mean flow velocity and flow profile are optimized within the rectangular and reduced cross section, the additional uncertainty for upstream disturbances is drastically reduced. The water meter can be installed directly behind 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. The Rilsan®coating of the flow sensor is chemically resistant, durable and maintenance-free, flexible and tough, smooth and pore-free and free of solvents. The coating is widely used in the water industry and has received a wide range of drinking water certifications.

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. 3 2 4 1 1) Induced voltage(proportional to flow velocity) 2� Electrodes 3� Magnetic field 4� Field coils Rectangular cross section The minimal height of the measuring tube decreases the distance between the field coils (4), resulting in a stronger and more homogeneous magnetic field (3). In addition, the mean flow velocity v increases due to the rectangular and reduced cross section. The large electrode spacing (D) and the increased flow velocity results in a higher magnetic signal voltage, also in the presence of a low flow rate. 02/2012-4000572002-TD WATERFLUX 3000 R02 en www.krohne.com 7 TECHNICAL DATA 2.1 Technical data • The following data is provided for general applications. lfyou require data that is more relevant to yourspecific 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).

Therefore it is usually recommended to fit a straight inlet length in front of and straight outlet length behind a flowmeter. 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 and in front of and behind a meter are reduced. The NMi has performed tests with various flow and swirl disturbers according to ISO 4064 and EN 14154.
