TRIO-WIRL V flow meters are based on the principle of the Karman` Vortex street. The system has a freely configurable, two-line LC display for the actual flowrate and totalisation. Settings can be changed directly via 3 push buttons or via magnet sensors with closed housing.

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. TRIO-WIRL Vortex-meter are available as compact or remote design with 10m cable length.

  • Size range flange:
    DN 15 (1/2”) to DN 300 (12”),
    wafer: DN 15 (1/2”) to DN 150 (6”)
  • DSP converter with most modern digital filter technology for the safe detection of also weakest sensor signals
  • Very robust and simple primary
  • Optionally integrated PT100 e.g. for very economic massflow-measurement of saturated steam or for temperature monitoring/alarms
  • DIN-wafer instruments in dazzle-compatible installation length (65 mm) for easy replacement of standard orifices
