The WKF-LWGY series turbine-type flow meter has a simple structure, high precision, good repeatability, sensitive response, easy installation, and maintenance. If matched with a display instrument with special functions, it can also carry out quantitative control, excessive alarm, etc. It is an ideal instrument for flow measurement and energy conservation.

 

Principle

When the measured fluid flows through the sensor, under the action of the fluid, the impeller is forced to rotate, and its rotating speed is proportional to the average flow rate of the pipe. The rotation of the impeller periodically changes the reluctance value of the magneto-electric converter, and the magnetic flux in the detection coil occurs accordingly. Periodic changes occur, producing an induced potential with the same frequency as the rotation, that is, an electrical pulse signal, which is amplified by the amplifier and sent to the display instrument for display.

  • Good repeatability, with short-term repeatability reaching 0.05%~ 0.2%;
  • It is precisely because of its good repeatability, such as frequent calibration or online calibration, that it can achieve extremely high accuracy.
  • It is a commonly used flowmeter in trade settlement; High-precision, generally available at 1% R and 0.5% R, and high-precision models at 0.2% R.
  • Output pulse frequency signal, no zero drift, strong anti-interference ability;
  • It can obtain very high frequency signals (3~4kHz) with strong signal resolution; The range is wide, with a medium and large aperture reaching 1:20 and a small aperture reaching 1:10;
  • Compact and light structure, convenient installation and maintenance, and large circulation capacity;
  • It is suitable for high-pressure measurement. It does not need to open holes in the instrument body, making it easy to make high-pressure instruments.
  • It can be made into a plug-in type, suitable for large-diameter measurement, has a small pressure loss, a low price, can be taken out continuously, and is convenient for installation and maintenance.
