Vortex Flow Meter (HMT. VFM)

Digital vortex flow meterDigital Vortex Flow Meter, Pipe size is from 15mm to 500mm Accuracy is ± 0.5% or ± 1.0% Max pressure ≤ 4.0Mpa, Medium temperature 50- +350ºC, Explosion-proof is ExdIIBT4/ Exib IICT4, Output signal: 4-20mA; RS485; HART. Our Digital Vortex Flow Meter is widely used for Water Sewage seawater, Water distribution, Power Plants cooling water, Boiler feed water, Mining leaching and return flows, Liquid petroleum products, Pipeline leak detection, Energy management systems Process plant water and chemicals.

SummaryWith on-site display function, Can be built-in or integrate temperature, pressure sensor to realize compensation function, With "HART" protocol advanced features. Intelligent circuit according to the characteristics of vortex sensor, the detection and closely integrated totalizer. We use sophisticated low-power 128 x 64 full DOT matrix LCD display, local display instantaneous flow and total flow, and measuring the temperature and pressure compensation, display data-rich and intuitive. Common operating principle set the menu, and prompts the use of English letter, clear and intuitive, easy to operateFeatures1) Multi-point linear correction to achieve the full real-time linear compensation, to achieve a linear ability to compensate2) To convert working conditions flow rate into the mass flow or volume flow under standard conditions directly, measuring simple and precise3) 12 kinds of compensation algorithm to fit almost all working condition compensation calculation, rely on external data signal correction curveAnd the calibration of standards-based way, greatly improve the measurement accuracy.4) Through manual setting to do various amendments, parameters setting, functions setting thus that the instruments adapts to various pipeline andAll kinds of measure media.5) Signal Output: Three wire with a linear correction of the pulse output and three-linear correction current output, with RS485 communications,And battery-powered; The wire 4-20mA output can be multi-linear correction, and provides isolation of the original pulse output.6) HART communication can be configured and read the measurement data comply international standardsSpecificationPipe size: DN15 to DN500 (Other by negotiation )Accuracy: ± 1.0% repeat better than 0.33%; ± 0.5% repeat better than 0.15%Operate pressure: 16Bar; 25Bar; 40Bar; 63BarMedium temperature: (-50 +250)º C, (-50 +350)º CDisplay method: 128x 64 LCD displayProtection class: IP65, IP67, IP68Environment temperature: -30 +70º C(-20 +60º C for LCD display)Environment: -40 +55º C, RH: 5% 90% atmospheric pressure 86 106KPaExplosion-proof: ExdIIBT4/ ExibIICT4Three wire outputPower supply: 12~24VDC, or BatteryOutput method: Pulse signal output; Three wire 4~20mA with linear calibration; RS485 communication is optionalTwo wire outputPower supply: 15~24VDCOutput method: 4~20mA with linear calibration is optional; Optical isolation without amendment the original pulse output (Need an additional power supply)HART communicationApplication1) Universal gas and liquids include corrosive medium, caustic solutions, water, compressed air, ammonia, chlorine, other chemical gases hot water, saturated steam, super-heated steam, natural gas and so on2) Water Sewage seawater3) Water distribution4) Power Plants cooling water5) Boiler feed water6) Mining leaching and return flows7) Liquid petroleum products8) Chemicals9) Pipeline leak detection10) Energy management systems11) Process plant water and chemicals
