Product Description Product DescriptionIntelligent precession vortex flowmeter is a new type of gas flow meter developed by Aister Instrument. The flowmeter integrates the function of flow, temperature and pressure detection, and can automatically compensate the temperature, pressure and compression factor. It is an ideal instrument for gas measurement in petroleum, chemical industry, electric power, metallurgy and other industries.The flow profile of the flow sensor is similar to the profile of a venturi tube. A set of helical vane is arranged on the inlet side. When the gas flow enters the flow sensor, the vane forces the flow to produce a violent vortex flow. When the gas flow enters the diffusion section, the vortex flow begins to rotate twice under the action of backflow, forming a gyroscopic vortex precession phenomenon.The precession frequency is proportional to the flow rate and is not affected by the physical properties and density of the flow, and the detection element can measure the secondary rotational precession frequency of the fluid to obtain good linearity in a wide flow range. The signal is amplified, filtered, and transformed into a pulse signal proportional to the flow rate by the preamplifier, and then sent to the microprocessor for integration processing together with the temperature, pressure and other detection signals, and the measurement results are displayed on the LCD screen (instantaneous flow, cumulative flow, temperature and pressure data).The smart precession vortex flowmeter consists of the following seven basic components:1. Vortex generator2. Shell3. Intelligent flowmeter integrator4. Temperature sensor5. Pressure sensor6. Piezoelectric crystal sensor7.DisrotatorProduct ParametersPerformanceTechnical parameterDiameter(mm)2025325080100150200Flow range(M3/h)1.5~153~306~6010~15028~40080~900150~1800360~3600Accuracy1.0~1.5%RepeatabilityLess than 1/3 of the basic error limitWorking pressure(Mpa)1.6Mpa,2.5Mpa,4.0Mpa,6.3Mpa;Special pressure can consult customer serviceUse environmentAmbient temperature:-30oC~+65oCRelative humidity:5%~95%Medium temperature:-20oC~+80oCAtmospheric pressure:86Kpa~106KpaOperating voltage24VDC+3.6V battery powered, removable batteryOutput signal4-20mA,pulse output,RS485,alarm outputApplicable mediumAll gases (except those with corrosion and moisture)Explosion-proof markExiaIIT6GaDetailed PhotosProducts SizeCaliber (mm) Length(mm)PN1.6~4.0MPa H Dφ Kφ N L dφ HDφ Kφ NLdφ HDφKφNLdφ25200 305 115 85 4 14 65 32200 320 140 100 4 18 76 50230 330 165 125 4 18 99 80330 360 200 160 8 18 132 PN1.6MPa(Special requirements) PN2.5~4.0MPa 100410 376 220 180 8 18 156 390 235 190 822156 150570 430 285 240 8 22 211 450300250826 211 PN1.6MPa PN2.5MPa(Special requirements)PN4.0MPa200700 470 340 295 12 22 266 490 360 310 12 26 274 510 375 320 12 30 284Model Selection1.
