SUMOFLO® CPFM-8103 Low Flow

With extremely low flow rate achievable  to 0.002 kg/min. and accuracy of ±1.5% of reading, the SumoFlo® CPFM-8103-series Low Flow Single-Use Coriolis Mass Flow Meter is an advanced patented flow meter based on the Coriolis principle. Featuring flow ranges from 0.002 to 0.05 kg/min, SumoFlo® Low Flow Coriolis Flow Meter is specially designed for measuring liquids in high-purity bio-pharmaceutical and other applications that require all gamma-sterilizable wetted surfaces. Due to patented Coriolis technology, SumoFlo® Low Flow Meters offer ±1.5% accuracy of mass flow rate readings that is unaffected by flow regime or variations to the velocity profile, allowing for accurate measurements of bubbly or frothy fluids.

The SumoFlo® Low Flow Coriolis Flow Meter is the world's only gamma-sterilizable Coriolis mass flow meter, and is available in a disposable, drop-in form factor for single-use applications. The fluid contacting surfaces are made of unreinforced PEEK (Polyether ether ketone) that meet USP Class VI, USP 661, and USP 788 standards.

Optional Integral Display Transmitter now available option for use with SumoFlo® CPFM-8103-Series Low Flow Single-Use Coriolis Flow Meter. The display transmitter features an 144 x 144mm panel mounted four line display which can simultaneously display:

  • Flow Rate
  • Totalized Flow
  • Temperature

Additionally, the SumoFlo Integral Display Transmitter, offers re-zero and reset the totalizer capabilities form the front of the display panel. Available in either panel mounted or table-top version, the display transmitter is a durable component, that can be reused since it has no contact with fluids. The SumoFlo Integral Display Transmitter provides users with instantaneous process metrics, enabling operator to identify and respond to process variations and failures quicker with less wasted time and materials.

Designed and Assembled in California, USA, from American and imported materials. This product is protected by U.S. and International patents.

For high flow ranges up to 100 kg/min SumoFlo® is also available in seven other models.


  • Fluid measurement performance is independent of fluid properties; eliminating the need to calibrate on different fluids
  • Accuracy is unaffected by flow regime (e.g., laminar or turbulent flow) or variations in flow velocity profile
  • 1/8" barb connections
  • Supports fluid flow ranges from 2 g/min to 50 g/min.
  • Disposable drop-in sensor option for single use applications
  • CE Marking certified
  • Custom sensor mounting cradle available
  • Accuracy:  +/- 1.5% of mass flow rate reading or +/- 0.3 g/min, whichever is higher
  • Optional Integral Display Transmitter to display – flow rate, totalized flow, and temperature on 144 x 144mm display panel to provide users instantaneous process metrics


  • Liquids
  • 1/8"
