Optiswirl 4070

Vortex Flow Meter - Optiswirl 4070
The all-in-one solution

The OPTISWIRL 4070C is the only vortex flowmeter with integrated pressure & temperature compensation in 2-wire technology. The OPTISWIRL 4070C provides reliable measurement of operating, standard, volumetric and mass flow of conductive & non - conductive liquids, gases and vapours, even with fluctuating pressures and temperatures.


  •  2-wire device with integrated pressure and temperature compensation.
  •  Non -wearing, fully welded stainless steel construction with high corrosion, pressure and temperature resistance.
  •  Optimal process reliability thanks to Intelligent Signal Processing (ISP) - stable readings, free of external perturbations.
  •  Ready to use immediately thanks to plug & play.
  •  Maintenance free sensor design.
  •  PACTware available at no extra cost.
  •  Pressure & Temperature can be called up via HART.
