AVF7000 Series

Products // Vortex Flowmeter

AVF7000 Series AVF7000 is a Vortex Flowmeter based on Von Karman theory of vortices generated by a bluff body in the pipe. The number of vortices are linearly proportional to the volumetric flow in the pipe.The AVF7000 is versatile flowmeter widely used for Gases, Steam & Liquid applications. There are no moving parts and comes with either Flange or wafer connection. Standard configuration has local indication for flowrate and total flow as well as a 4-20mA output functions. The microprocessor design can filter out erroneous signals as well as interfence caused by pipe vibration. FEATURES  Simplified setup and self-diagnostic functions  Auto. Temperature & Pressure compensation  4-20 mA and pulse outputs, user selectable  A very wide selection of sizes  Wide temperature range up to 420 Deg. C  Non-volatile memory for setup and calibration   SPECIFICATION Size: Local Display: 15,20,25,32,40,50,65,80,100,125,150 4 lines LCD 200,250,300,350,400,450,500mm 8 digit flowrate Measuring Range: 8 digit Totalizer Steam - 1.6 to 540,000 Kg/Hr Current Output: Gas - 3 to 46,000 M3/Hr 4-20 mA (2 wire) Liquid - 0.3 to 4950 M3/Hr Load Material: 600 Stainless Steel 301 / 304 / 316 Pulse Output: Accuracy           Liquid: Scale Pulse (3 wire) +/-0.7% value of reading Rating Gas & Steam 3 to 30VDC, 20mA Max. +/-1.0% value of reading Communication: Unit: RS485(MODBUS Protocol) m3/h,km3/h,l/min,kg/h,t/h Data Storage: Repeatability: Operation parameter and totalizer +/-0.2% value of reading figures are stored by EEPROM for more Process Connection: than 10 years Flange / Wafer Housing Material: Flange type Aluminum Alloy JIS 10K / JIS 20K / JIS 40K Cable Entry: ANSI 150# / ANSI 300# / ANSI 600# Standard :M20 Option:1/2"NPTF DIN PN 10 / PN 16 / PN25 / PN 40 Power supply: Wafer type 12-36 VDC DN40~DN250 Ni-MH Battery (3 years working Hours) without Temperature / Pressure Sensor KeyPad: Temperature: 4 internal keys for programming -40 ~ +280 oC (Standard) and display control -40 ~ +420 oC (Optional) Option: Ambient Temperature: Pressure Sensor -20 ~ +60 oC Pressure compensation Pressure: Signal output 78 Kg/cm2 (Max.) 0-30 mV DC (20 uA Power supply) Protection Class: Temperature Sensor IP 65 Temperature compensation Explosion Proof, Exd IIC T6 Signal Output Intrinsically Safe, Eex ia IIC T4 PT100 (3 wires)
