三.技术参数
测量原理 科氏力质量流量计产品标题 The flowmeter with minimized total cost of ownership and a compact, easily accessible transmitter. Accurate measurement of liquids and gases for a wide range of standard applications.传感器特点 Cost-effective – multi-purpose device; an alternative to conventional volumetric flowmeters. Fewer process measuring points – multivariable measurement (flow, density, temperature). Space-saving installation – no in/outlet run needs. Compact dual-tube sensor. Medium temperature up to +150 °C (+302 °F).变送器特点 Full access to process and diagnostic information – numerous, freely combinable I/Os and fieldbuses. Reduced complexity and variety – freely configurable I/O functionality. Integrated verification – Heartbeat Technology. Compact dual-compartment housing with up to 3 I/Os. Backlit display with touch control and WLAN access.公称口径范围 DN 8 to 80 (?6?2 to 3')接液部件材质 Measuring tube: 1.4539 (904L) Connection: 1.4404 (316/316L)测量变量 Mass flow, density, temperature, volume flow, corrected volume flow, reference density, concentration 测量误差 Mass flow (liquid): ±0.15 % (standard), ±0.10 % (option) Volume flow (liquid): ±0.15 % Mass flow (gas): ±0.75 % Density (liquid): ±0.0005 g/cm3测量范围 0 to 180 000 kg/h (0 to 6615 lb/min) 过程压力 PN 100, Class 600, 63K 介质温度范围 –40 to +150 °C (–40 to +302 °F)环境温度范围 Standard: –40 to +60 °C (–40 to +140 °F) Option: –50 to +60 °C (–58 to +140 °F) 传感器外壳材质 1.4301 (304), corrosion resistant变送器外壳材质 AlSi10Mg, coated; stainless steel for hygenic transmitter design 防护等级 Standard: IP66/67, Type 4X enclosure IP69显示/操作 4-line backlit display with touch control (operation from outside) Configuration via local display and operating tools possible Remote display available' 输出 3 outputs: 4-20 mA HART (active/passive) 4-20 mA WirelessHART 4-20 mA (active/passive) Pulse/frequency/switch output (active/passive) Double pulse output (active/passive) Relay output输入 Status input 4-20 mA input 数字式通信 HART, PROFIBUS PA, FOUNDATION Fieldbus, Modbus RS485, Profinet, Ethernet/IP, OPC-UA电源 DC 24 V AC 100 to 230 V AC 100 to 230 V / DC 24 V (non-hazardous area)
