Electromagnetic flow measurementApplication AreasThe M3000 and M4000 flow meters are specifically designed for flow measurement in the pharmaceutical and chemical industries, as well as for all water and wastewater treatment sites classified as hazardous areas.Flange connectionAccuracy: ±0.2% of measured flowFlow range: 0.03 - 12 m/sIP67 protectionFor use in hazardous areasDN 6 - 600 (1/4"- 56")Product DetailsThe transducer is used for flow measurement in hazardous areas classified as Ex zone 1 and 2, in compact or remote mounting. The electronics are housed in a die-cast aluminum enclosure with IP67 protection. An internal divider ensures physical separation from 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 shows the measured flow, totalizers, and various status messages. By adjusting the coil excitation frequency, the M3000 and M4000 converters can be adapted for use in challenging applications. The new electronics offer greater 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, RepeatabilityLess 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 indicatorProgramming3 buttons or via magnetic penInterfaceRS232 for measurement 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 VDC, 25 mA, passive 24 VDC, 20 mA (max. 0.5 W)Frequency outputmax. 10 kHz (open collector)Status indication outputMin/max alarm, preset, flow direction, error message (freely configurable)Empty pipe detectionSeparate electrodeLow speed cut-off0-10%CaseCast aluminumProtectionIP67Cable entry3 x M 20Operating temperatureFrom -20 to +60°CHazardous area approvalsM3000:FM/CSA class I, div. 2 / zone 2ATEX II 3 G Ex nA ia IIC T3 Ta = from -20°C to +50°C, IP66 (complete flowmeter)ATEX II 3 G Ex nA [ia] IIC T3 Ta = from -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 = from -20°C to +50°C, IP66 (complete flowmeter)ATEX II 2 G Ex d [ia] IIC T4 Ta = from -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: from PN 10 to PN 100TypeDiameterFluid TemperatureNeopreneDN 25 to 600From 0 to 80°CHard rubberDN 25 to 600From 0 to 80°CPFADN 6 to 10From -40 to +150°CPTFEDN 15 to 200From -40 to +150°CHalarDN 300 to 600From -40 to +150°CTechnical Specifications / FeaturesElectromagnetic flow measurement for hazardous areas (ATEX)Models: M3000 (zone 2), M4000 (zone 1)Accuracy: ±0.2% of measured valueRepeatability: Range: 0.03 - 12 m/sBidirectional measurementIP67 protectionLCD display, 4 linesRS232 interfaceAnalog and pulse outputsOperating temperature: -20 to +60°CFlange mounting, DN 6 to 600Various liner materials: Neoprene, hard rubber, PFA, PTFE, HalarHazardous area certifications: ATEX, FM/CSA
