Overview as standard
WaterMasters has a wide range of built-in functions and user advantages: • bi-directional flow • unique self calibration transmitter (patent), with the highest stability and repeatability • OIML type continuous self-test, with alarm, Ensure the accuracy of sensors and transmitters • Real electrode and coil impedance measurement • Integrated analog mode • Universal switch mode power supply (AC and DC power supply options) • Integrated self diagnosis in line with NAMUR NE107 • Programmable multiple alarm functions • Bus options: HART (4 to 20 mA), PROFIBUS DP (RS485), MODBUS (RS485) • Three configurable pulse/frequency and alarm outputs • Advanced infrared service port supports remote HMI, HART Cyclic data output and parameter download • VeriMaster field verification software optional • Read only switch and super security service password, used for comprehensive security WATERMASTER electromagnetic flowmeter | DS/WM-EN REV. Y 5 The WaterMaster approved by OIML/MID has passed the type test and has been internationally recognized. The highest accuracy level available for hot and cold drinking water meters is Level 1 and Level 2 - OIML R49-1 (International Organization for Measurement). More information can be found at www.OIML OIML R49. org.
Sensor Status
Its requirements are very similar to other international standards, such as EN14154 and ISO4064. WaterMaster has passed the type approval of OIML L49 by the National Metrology Office (NMO), and has passed the highest precision identification of DN40 to DN200 (11/2 to 8 inch NB). Certifications apply to: • Accuracy class 1 and 2 (calibration option) • Ambient class T50 for water temperatures from 0.1 to 50 ° C (32.18 to 122 ° F) • Electromagnetic environment E2 (10 V/m) • Any pipe direction • 5 diameter upstream pipe • 0 diameter downstream pipe • Pressure loss class<0.25 bar (3.62 psi) • Integrated or remote transmitter (<200 m [<656 ft.] cable) • DN40 to DN200 (11/2 to 8 in. NB), A major improvement of the two-way flow WaterMaster is that its self inspection capability meets and exceeds R49 requirements. It is the first electromagnetic flowmeter to pass OIML P-type permanent self inspection during normal operation (not only during startup), and provides the following alarm indications: • Transmitter and sensor status, With accuracy alarm • Program ROM and RAM status • Dual independent storage of accumulator values in sensor and transmitter non-volatile memory • Display test OIML R49-1 certificate of conformity can be obtained from the following website:. Aspx WaterMaster was also approved in accordance with the European Union Measuring Instruments Directive (MID) 2004/22/EC, which covers the use of water meters for certain applications. MID WaterMaster can prevent tamping, and can be used as an option with the fingerprint of ABB VeriMaster's on-site verification products. The printing accuracy of the certificate is ± 1%. The WaterMaster certificate for EC type inspection of measuring instruments can be obtained from the following website:
