Electromagnetic Flow MeasurementApplication AreasThe M3000 and M4000 flow meters are specially designed for flow measurement in the pharmaceutical and chemical industries, as well as for all waterworks and water treatment plants in hazardous areas.AdvantagesFlange connectionAccuracy: ±0.2% of measured flowFlow range: 0.03 - 12 m/sIP67 protectionUsable in hazardous areasDN 6 - 600 (1/4"- 56")FeaturesThe transmitter enables flow measurement in Ex-classified hazardous areas of Zone 1 and 2 in compact or remote installation. The electronics are housed in a cast aluminum enclosure with IP67 protection. An internal partition allows physical separation of the various connection terminals. Configuration can be performed with the cover closed using a magnetic pen or with the cover open using 3 buttons. The 4-line display allows the display of measured flow, totalizers, and various status messages. The adjustment of the excitation frequency of the coils allows the M3000 and M4000 converters to be adapted to difficult applications. The new electronics offer higher measurement accuracy, especially at low flow rates.Power supply85 - 265 VAC, 45-65 Hz less than 20 VA, 24 VDC optionalAccuracy±0.2% of measured flow, ≥0.5 m/s±1.25 mm/s of measured flow, <0.5 m/sRepeatabilityLess than 0.1% of full scaleRange0.03 - 12 m/sConductivitymin. 5 µS/cm (20 µS/cm for demineralized water)Flow directionBidirectionalDisplayLCD, 4 lines / 16 characters, backlit, flow, 3 totalizers and status displayProgramming3 buttons or via magnetic penInterfaceRS232 for measured values and programmingAnalog output0/4-20 mA ≤750 Ohm, flow direction indicated on a separate logic outputPulse outputActive or passive, 2 open collectors and 2 relaysOpen collector: active 18 V DC, 25 mA, passive 24 V DC, 20 mA (max. 0.5 W)Frequency outputmax. 10 kHz (open collector)Status outputMin./Max. alarm, preselection, flow direction, error message (freely configurable)Vacuum tube detectionSeparate electrodeLow cut-off0-10%HousingCast aluminumProtectionIP67Cable entry3 x M 20Operating temperature-20 to +60°CHazardous area approvalsM3000:FM/CSA class I, div. 2 / Zone 2ATEX II 3 G Ex nA ia IIC T3 Ta = -20°C to +50°C, IP66 (complete flow meter).ATEX II 3 G Ex nA [ia] IIC T3 Ta = -20°C to +50°C, IP66 (converter only)M4000:FM/CSA class I, div. 1 / Zone 1ATEX II 2 G Ex d e ia IIC T3 Ta = -20°C to +50°C, IP66 (complete flow meter)ATEX II 2 G Ex d [ia] IIC T4 Ta = -20°C to +50°C, IP66 (converter only)Flange mounting for hazardous area type VAvailable diameters: DN 6 to 600 (M3000) or DN 6 to 300 (M4000).Nominal pressure: PN 10 to PN 100TypeDiameterLiquid temperatureNeopreneDN 25 to 6000 to 80°CHard rubberDN 25 to 6000 to 80°CPFADN 6 to 10-40 to +150°CPTFEDN 15 to 200-40 to +150°CHalarDN 300 to 600-40 to +150°CPower supply: 85 - 265 VAC, 45-65 Hz, less than 20 VA, 24 VDC optionalAccuracy: ±0.2% of measured flow, ≥0.5 m/s; ±1.25 mm/s of measured flow, <0.5 m/sRepeatability: Less than 0.1% of full scaleRange: 0.03 - 12 m/sConductivity: min. 5 µS/cm (20 µS/cm for demineralized water)Flow direction: BidirectionalDisplay: LCD, 4 lines / 16 characters, backlit, flow, 3 totalizers and status displayProgramming: 3 buttons or via magnetic penInterface: RS232 for measured values and programmingAnalog output: 0/4-20 mA ≤750 Ohm, flow direction indicated on a separate logic outputPulse output: Active or passive, 2 open collectors and 2 relays; Open collector: active 18 V DC, 25 mA, passive 24 V DC, 20 mA (max. 0.5 W)Frequency output: max. 10 kHz (open collector)Status output: Min./Max. alarm, preselection, flow direction, error message (freely configurable)Vacuum tube detection: Separate electrodeLow cut-off: 0-10%Housing: Cast aluminumProtection: IP67Cable entry: 3 x M 20Operating temperature: -20 to +60°CHazardous area approvals: See above
