Volume flow meter EFTN series

for liquidsfor gasfor steam

EFTN target flow meter can be used for measuring flow of liquid，gas and steam, and convert it to analog output signal of 4-20mA. Not only have they the character of no moving part such as orifice plate and vortex street, but also have perfect accuracy that can be compared with the precision of volume meter. Meanwhile, they have features of anti-interference, dirty resistance proof, simpleness with good reliability. They can be widely used in petroleum, chemical, energy, food, environment protection and water conservancy, etc. Have great high sensitivity. can measure extremely slow flow rate, even 0.8m/s Measuring accurately, the accuracy is 0.5、1.0、1.5、2.5 class Nominal diameter: 15-1200mm Nominal pressure: ≤42.0MPa Operating temperature: -196℃ ~ +450℃ Measuring medium: liquid，gas，steam Have large measuring range, max. range is 1:10 Have excellent repeatability. The general repeatability is 0.1% Have small pressure loss. The pressure loss is only about half of one with throttle orifice plate. Compensation function: with temperature and pressure compensation You can use dry calibration method, that is hanging weight method. The measuring range can be changed by changing size of target plate according to actual requirement. Display in field and through remote communication Explosion-proof: intrinsically safe type (ExiaⅡCT2~T6) Explosion isolation type(ExdⅡCT2~T6) Protection class: IP 67
