SUMOFLO Single Use Coriolis Flow Meter

PSG BiotechThe extremely accurate SUMOFLO® CPFM-8103SumoFlo® CPFM-8103-series Single-Use Coriolis Flow Meter provides best in class accuracy of ±1% of reading. With flow ranges from 0.05 to 100 kg/min, SumoFlo® Coriolis Flow Meter come in seven models and 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® Flow Meters offer ±1% 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® 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.

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

SumoFlo® is also available in a low flow version with a flow rate range of 0.002 to 0.05 kg/min.
