3 nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn OPTIFLUX 2000 OPTIFLUX 2000 for the water and wastewater industry OPTIFLUX 2000 has been designed for measuring potable water and water with suspended particles. Throughout the history of our company, KROHNE development and application engineers have been continuously pushing the limits of feasibility in developing and testing new instruments. The results are innovations that go far beyond the requirements of the customer, thereby setting new standards for the market. OPTIFLUX 2000 is designed for "commercial" use according to European Directive MI-001. The level of precision complies with the latest stipulations of the ISO/EN and MI-001 standards, with a ratio of 400 between Q1 and Q3 within the legal requirements. However, OPTIFLUX 2000 also means "proved by KROHNE"; this covers specific trials, measurements and tests that go beyond the legal specifications and on which our customers can rely 100 percent. For example, we subject the OPTIFLUX 2000 electronics to a series of extensive temperature change tests, in which the converter is exposed to cyclical fluctuations from C. Every OPTIFLUX 2000 meter that leaves our factory is first wet-calibrated on our officially certified calibration rigs (EN 17025). 3

4 OPTIFLUX 2000 nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn Construction The OPTIFLUX 2000 measuring tube has a smooth, cylindrical shape. This design, consisting of a circular cross section (no internal or moving parts) and a homogeneous magnetic field, forms the basis for a flow-optimized pipe cross section, thereby providing reliable measurements that are largely independent of the flow profile. This design has obvious advantages. OPTIFLUX 2000 can measure the flow bidirectional. As an additional benefit, it optimizes the precision of the measurement results, thanks to high sampling rates. And it does this with minimum consumption, an indispensable advantage, for example during night time operation. In addition, the required straight inlet and outlet runs are only 3D or 2D. The lining of the measuring tube is made of polypropylene or hard rubber and is resistant to corrosion, aging and abrasion. As a result, OPTILFUX 2000 is a food-grade water meter in accordance with KTW/DVGW-W270 and therefore also certified for drinking water. The surface and shape of the measuring tube also minimize mineral deposits, resulting in exemplary measurement quality even over the long term. Communication Bulk water meters are installed in places like remote shafts, deep well-connecting chambers and public drinking water networks. The ability to read the measured results on-site may be standard, but it does not always meet the current and actual needs of the user or operator. That is why OPTIFLUX 2000 comes with optional, state-ofthe-art fieldbus communication systems. The stored data is transmitted (e.g., once a day) by HART, Profibus, Fieldbus or Modbus, and then forwarded to a management system. 4

5 nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn OPTIFLUX 2000 Design and performance Electromagnetic water meters have many important advantages over their mechanical counterparts: outstanding long-term stability, maximum process reliability, no maintenance to name just a few. As a result, OPTIFLUX 2000 can deliver precise and reliable measurements for many years. Yet OPTIFLUX 2000 can do a whole lot more. The water meter has extensive factory-set diagnostic functions that provide continuous self-diagnosis in accordance with the applicable standards such as OIML R-49, EN 14154, ISO 4064 and MI-001. Converter operation is also monitored continuously, as are the sensor electrodes, the flow profile and electronic functions. Malfunctions and irregularities are detected and immediately displayed on the high-contrast, high-resolution display. Operating principle 1 Voltage (induced voltage proportional to flow) 2 Electrodes 3 Magnetic field 4 Field coils 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 main flow velocity v and thus the flow rate q. The signal voltage is quite small (typically 1 mv at v = 3 m/s (10 ft/s) and field coil power of 1 W). Finally, a signal converter is used to amplify the signal voltage, filter it (separate from noise) and convert it into signals for totalising, recording and output processing. 5
