What is Swirl Flow Meter?

Swirl flow meter provides all the advantages of the vortex flow meter by needing shortest upstream / downstream distances, typical 3 XDN/1XDN. As the vortex flow meter, the swirl flow meter is based on the principle of frequency measurement. The system has a freely configurable, LCD display for the actual flow rate and tantalization. Settings can be changed directly via 3 push buttons. Additional to the 4-20mA analog signal a freely configurable switching output is already available. This can be used universally as pulse output, high-low alarms or for system supervision. Swirl flow meter is available as compact for remote design with 10 m length cable.


Features of Swirl Flow Meter

  • Built-in pressure, temperature, flow sensors, security, high performance, compact structure, beautiful shape.
  • Using new signal-processing amplifier and unique filtering technology to effectively eliminate the pressure fluctuations and pipe vibrations generated by the interference signal, greatly enhanced the anti-jamming capability flowmeters, so that small flow with excellent stability.
  • No mechanical moving parts, the use of easy maintenance.
  • Pairs of straight pipe before and after the meter installation requirements low (former straight pipe ≥ 3D, after the straight pipe ≥ 1D).
  • Advanced computer technology and high-performance microcontroller, so that machine more powerful and better performance.
  • Intelligent design can be integrated dynamically detect medium temperature and pressure, and compression factor for automatic compensation and amendments to the standard instantaneous direct display of gas flow and the standard volume of the total volume.
  • Using RS485, RS232C, MODBUS protocol with dedicated MODEM supporting, through the telephone network to build automated meter reading management system, high degree of automation
