Equflow Disposable PVDF Flowmeter

This Disposable Turbine flow meter has low flow capabilities in a wide range of flow processes and is mainly developed to perform a fast exchange of the flow tube in single-use applications (for hygienic reasons with regards to usage in Pharmaceutical- and Bio medical industries).

Despite the name 'Single-use' these devices are also suitable for long- term measurement.

  • Suitable for opaque liquids as well
  • Performs a fast exchange of the flow tubes
  • Flow Measuring through revolutionary Infra Red turbine rotor reflection
  • Highly chemical and corrosive resistant PVDF
  • PVDF meets all the requirements of the US Pharmacopeia Class VI
  • The flow tube can be sterilized up to 140º C.
  • Gamma radiation resistant up to 50 kGy
