ATF2000 Series

ATF2000 Series ATF2000 Series thermal mass flow meter is designed on the basis of thermal dispersion. It adopts method of constant differential temperature to measuring gas flow. It has the advantages of small size, high digitization, easy installation and high accuracy. ATF2000 is a multi-functional thermal mass flow meter that measures mass flow and volume flow. With insertion type connection, the meter can achieve a hot-tapped installation and maintenance. FEATURES  Wide flow range: 0.1-120 m/s for gas    Turndown ratio of least 100:1    Temperature range up to 350 oC    Good vibration resistance and  long service life    Hot-tap installation. Easy to install & maintain    No moving parts, no wear, maintenance-free, low pressure loss    Multiple installation options: Flange, thread, wafer, clamp and insertion    Direct mass flow measurement of gases. No additional pressure and temperature compensation      SPECIFICATION Size: Unit: 10,15,20,25,32,40,50,65,80,100,125,150, Nm3/hr, kg/hr, NL/min, kg/min, SCFH, PPH,  200,250,300,350,400,450,500,¡­7000 mm SCFM, PPM Measuring Range: Temperature: 0.028 Nm3/hr-13854000 Nm3/hr -40~200 oC(Standard) 0.036 kg/hr-17872000 kg/hr -40~350 oC(Option) Turndown Ratio: Ambient Temperature: Over 100:1 -20~60 oC Accuracy: Pressure: +/-1.0% of reading +/-0.5% FS 63 kgf/cm2 (Max.)
