high precise flow meter-EFTN flexible rod target flow transmitter is developed force induction target plate flow transmitter
high precise flow meter-EFTN serial flexible rod target flow transmitters are newly developed force induction target plate flow transmitters, being based upon the basic measuring principle of target plate transmitters, absorbing and adopting their optimum merits, integrating with new sensor technology and contemporary digital technology. Not only have they the character that there is no moving part such as traditional target plate flow transmitters, throttle devices and vortex flow transmitters, but also have perfect accuracy that can be compared with the precision of volumetric flow transmitters. Meanwhile, they have features of anti-interference, dirty resistance proof, simpleness with good reliability. They can be extensively used in petroleum, chemical, energy, food, environment protection and irrigation industries, etc. So, EFTN serial target plate flow transmitters have great adaptability.
• It is suitable for different diameters, DN15~DN600mm or larger
• It is suitable for mediums at high or low temperature: -196°C~450°C
• It is suitable for applications at high pressure: 0 MPa~42MPa(gauge pressure)
Technical features
• Can accurately measure flowrate of different kinds of liquid, gas and steam at normal, high and
low temperature, even sticky liquids
• Have great high sensitivity. Even can measure extremely slow flowrate, even 0.8m/s
• Be safe and reliable without moving parts
• Measure accurately with high precision. The accuracy is 0.2% (weighing calibration)
• Have large measuring range. Max .measuring range ratio can be up to 1:10
• Have excellent repeatability. The general repeatability is 0.1~0.08%
• Have small pressure loss. The pressure loss is only about half of one with throttle orifice plate
• The measuring range can be changed by changing size of target plate
• Display in field or through remote communication
• Easy installation and maintenance
