Electromagnetic flow measurementApplication FieldsThe M3000 and M4000 flowmeters are specifically designed for flow measurement in the pharmaceutical and chemical industries, as well as for all water treatment facilities classified as hazardous areas.BenefitsFlange 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 zones 1 and 2, in compact or remote mounting. The electronics are housed in a die-cast aluminum enclosure with IP67 protection. An internal partition allows physical separation of the different 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 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, 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 magnetic penInterfaceRS232 for measured values and programmingAnalog output0/4-20 mA ≤750 ohms, 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)Output frequencymax. 10 kHz (open collector)Status indication outputMin./max. alarm, preset, flow direction, error message (freely configurable)Empty pipe detectionSeparate electrodeLow velocity cut-off0-10%CaseDie-cast 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 flowmeter)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 flowmeter)ATEX II 2 G Ex d [ia] IIC T4 Ta = -20°C to +50°C, IP66 (inverter 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 100TypeDiameterFluid 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, Repeatability: 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 indicatorProgramming: 3 buttons or magnetic penInterface: RS232 for measured values and programmingAnalog output: 0/4-20 mA ≤750 ohms, flow direction indicated on a separate logic outputPulse output: Active or passive, 2 open collectors and 2 relays; Open collector: active 18 VDC, 25 mA, passive 24 VDC, 20 mA (max. 0.5 W)Output frequency: max. 10 kHz (open collector)Status indication output: Min./max. alarm, preset, flow direction, error message (freely configurable)Empty pipe detection: Separate electrodeLow velocity cut-off: 0-10%Case: Die-cast aluminumProtection: IP67Cable entry: 3 x M 20Operating temperature: -20 to +60°CHazardous area approvals: M3000: FM/CSA class I, div. 2 / zone 2; ATEX II 3 G Ex nA ia IIC T3 Ta = -20°C to +50°C, IP66 (complete flowmeter); ATEX II 3 G Ex nA [ia] IIC T3 Ta = -20°C to +50°C, IP66 (converter only).
