1 Data Sheet SS/MAG/WW Issue 2 Electromagnetic Flowmeter MagMaster Water & Waste Water Version Industry-specific design suitable for all applications found in the water and waste water industries Widest flow range, highest accuracy diameters from 5mm to 22mm (.5 to 84 in.) Submersible sensor suitable for flooded chambers and pits Buriable sensor eliminates chambers and ensures fast, low-cost installation Hazardous area approvals FM, CSA, ATEX ideal for waste water treatment works Built-in earthing (grounding) electrode eliminates the need for earthing (grounding) flanges 2-year warranty as standard high-quality product guarantees reliable maintenance-free operation CalMaster compatible in situ verification of flow meter calibration Remote communications including Profibus DP v MagMaster bringing unsurpassed flowmetering performance to the Water and Waste Water industries

2 Setting the Standard Designed specifically to target the diverse applications found in the supply and treatment of both potable and waste water, MagMaster sets new levels of accuracy, reliability and low cost of ownership. MagMaster's ground-breaking design guarantees long-term calibration stability, coupled with the wide range of sizes, 5 to 26mm (.5 to 2 in.), choice of lining and electrode material quickly established MagMaster as the de facto industry standard electromagnetic flow meter. Calibration Verification CalMaster is the world's first in situ calibration verification system. The system allows the calibration of MagMaster electromagnetic flow meters to be verified without the need for 'wet calibration'. The complex series of tests automatically performed by CalMaster is completed and a certificate produced without costly excavation of the sensor or disruption to the water supply. A complete solution to the regulatory requirement for routine verification and traceability of electromagnetic flow meters. Class-leading Flow Performance The combination of sensors with ultra-linear magnetics, proven technology, signal processing and sensor drive results in unsurpassed accuracy and an operable flow range of 5:. MagMaster's class-leading performance ensures reliable and accurate measurement over the widely varying flow rates, including minimal night flows, which occur in typical water and waste water systems. Assured Quality MagMaster is designed and manufactured in accordance with international quality procedures (ISO 9) and all flowmeters are calibrated on nationally-traceable calibration rigs to provide the end user with complete assurance of both quality and performance of the meter. For further information on CalMaster refer to the brochure PB/CALMASTER ABB operated national and internationally accredited flow calibration facilities in the UK, USA, Australia, Germany and India. 2

3 Electronic Display Unit Comprehensive display Forward, reverse and net totals 4 digital outputs: forward pulse, reverse pulse, alarm and alarm 2 2 analog outputs (output 2 optional) Communications: serial data (RS232), HART and Profibus DP v MagMaster is available with integral or remote transmitters, configuration is achieved either with a configurator of via the optional integral keypad. The software features multi-level password protection to prevent unauthorized configuration changes. In the 2-line display only variant, display data can only be changed using a magnetic wand, no operational parameters can be changed without the use of a configurator and appropriate passwords.

4 Easy, Low-cost Installation MagMaster sensors' rugged and robust construction ensure a long, maintenance-free life under the arduous conditions experienced in the water and waste water industry. The sensors are fully submersible, meeting the requirements of IP68 (NEMA6P) enabling installation in flooded chambers or metering pits. MagMaster sensors in all sizes are buriable. Installation merely involves excavating to the underground pipe, fitting the sensor, cabling back to the transmitter and then backfilling the hole. No metering chambers or pits are required so the installation is simple, fast and low cost. International Approvals Alternative versions of MagMaster are available for general locations with FM Approval and for Hazardous Area locations to ATEX, FM and CSA Standards. A brief summary of these Hazardous Area versions is given below, covering the safety designation inside the pipe. No external safety barriers are required.
