Electromagnetic flow measurementApplicationsThe M3000 and M4000 flowmeters are specifically designed for flow measurement in the pharmaceutical and chemical industries, as well as for all water supply and treatment facilities classified as hazardous areas.AdvantagesFlanged connectionAccuracy: ±0.2% of measured flowFlow velocity range: 0.03 - 12 m/sIP67 protectionFor use in explosive zonesDN 6 - 600 (1/4"-56")Product DetailsThe converter is used for flow measurement in hazardous zones 1 and 2, with compact or remote installation. The electronics are mounted in a cast aluminum housing with IP67 protection. An internal partition provides physical separation from 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. Thanks to the adjustment of the coil excitation frequency, the M3000 and M4000 converters can be adapted for use in challenging conditions. The new electronics provide increased measurement accuracy, especially at low flow rates.Power supply85 - 265 V AC, 45-65 Hz less than 20 VA, 24 V DC optionalAccuracy±0.2% of measured flow rate, ≥0.5 m/s±1.25 mm/s of measured flow rate, <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, reverse, flow, 3 totalizers, and status indicatorProgramming3 buttons or with a magnetic penInterfaceRS232 for measurement values and programmingAnalog output0/4-20 mA ≤750 Ω, flow direction displayed on a separate logic outputPulsed 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 indication outputMin/max alarm signal, preset, flow direction, error message (freely configurable)Empty tube detectionSeparate electrodeLow speed 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 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 (converter only)Flanged mounting for hazardous area Type VAvailable diameters: DN 6 - 600 (M3000) or DN 6 - 300 (M4000)Nominal pressure: from PN 10 to PN 100TypeDiameterLiquid temperatureNeopreneDN 25 - 6000 to 80°CHard rubberDN 25 - 6000 to 80°CPFADN 6 - 10-40 to +150°CPTFEDN 15 - 200-40 to +150°CHalarDN 300 - 600-40 to +150°CTechnical SpecificationsPower supply: 85 - 265 V AC, 45-65 Hz, <20 VA, 24 V DC optionalAccuracy: ±0.2% of measured flow rate (≥0.5 m/s), ±1.25 mm/s (<0.5 m/s)Repeatability: <0.1% of full scaleRange: 0.03 - 12 m/sMinimum conductivity: 5 μS/cm (20 μS/cm for demineralized water)Bidirectional flow measurementLCD display, 4 lines / 16 charactersProgramming: 3 buttons or magnetic penRS232 interfaceAnalog output: 0/4-20 mA ≤750 ΩPulsed output: 2 open collectors, 2 relaysFrequency output: max. 10 kHzStatus output: min/max alarm, preset, flow direction, error messageEmpty tube detection: separate electrodeLow speed cut-off: 0-10%Housing: cast aluminumProtection: IP67Cable entry: 3 x M 20Operating temperature: -20 to +60°CHazardous area approvals: see aboveFlanged mounting for hazardous area Type VAvailable diameters: DN 6 - 600 (M3000), DN 6 - 300 (M4000)Nominal pressure: PN 10 to PN 100Liner types: Neoprene, Hard rubber, PFA, PTFE, Halar
