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.

  • Fully welded bluff body
    No problems with pressure shocks

  • Sensor in the shadow of the bluff body

  • Extremely low mechanical stress on the pick up

  • No damage to the pick up due to passing solid contents

  • No possibility of deposits on the pick up

  • Only two sizes of sensor pickups for the entire range of VFM sizes

  • 2-wire instrument with integrated pressure- and temperature-
  • Fully welded st. steel construction with high corrosion-,
    pressure- and temperature resistance
  • Highest application reliability due to the Flodoc Intelligent Signal Processing

Stable measuring results

  • Maintenance free construction of the sensor
  • Possible to change the pressure sensor under process conditions.

  • Isolate the Pressure sensor for leakage and pressure tests
  • Self venting valve which can only be operated with a tool
