Krohne Vortex Flow Meter Optiswirl 4070

  • Vortex Flow Meter with integrated pressure and temperature compensation
  • Temperature compensation for saturated steam included as standard
  • Non-wearing, fully welded stainless steel construction with high corrosion, pressure and temperature resistance

Krohne’s Optiswirl 4070 vortex flow meter is a 2 wire device with integral pressure and temperature compensation for true mass flow rates.

The meter is ready to use from the box thanks to plug and play, and the design of the sensor ensures for maintenance free use.

The HART protocol is standard on the meter.

Maximum process temperatures are available up to 240 °c with process pressures available up to 100 bar.

Line sizes are available from DN15 up to DN300.

Measuring accuracy depends on media and state but can be up to ±0.75% of the measured value.

Atex versions are also available for intrinsically safe applications.


Common process applications and industrial uses include:

  • Vapour and saturated steam measurement
  • Steam boiler monitoring
  • Monitoring of compressor output
  • Measurement of consumption in compressed air systems
  • Measurement of consumption of industrial gases
  • SIP and CIP processes in the food, beverage and pharmaceutical industries
  • Measurement of conductive and non-conductive liquids
