CPFM-8800
High Purity Coriolis Flow Meter
All-PFA* wetted Coriolis flow meter
designed for measuring liquids in
high-purity applications
Features
• Fluid measurement performance is inde
pendent of fluid properties; eliminating the
need to calibrate on different fluids
• Accuracy unaffected by flow regime (e.g.,
laminar or turbulant flow) or variations in
flow velocity profile
• Sensors operate and measure in two-phase
flow condetions with gas volumetric void
fractions in excess of 30%
Description
The CPFM Series 8800 is a family of advanced flow meters based on
the Coriolis principle fabricated exclusively from PFA* (Perfluoroalkoxy) polymeric material.
Series 8800 flow meters are comprised of two assemblies: one containing the sensor, the other containing the supporting electronics.
Series 8800 sensors are specially designed for measuring liquids in
high-purity semiconductor, bio-pharmaceutical and other applications
that require all PFA-wetted* surfaces and provide a Mass Flow Rate,
Total Mass and Temperature.
*Model 8808-1 and 8808-2 are also available in PEEK wetted parts.
Measurement Principle
Fluid flows into the sensor consisting of two flow sensitive elements
which are vibrated relative to one another - similar to the tines of a
tuning fork. Fluid interacts with the sensor dynamically in such a way
that the sensor’s response is immune to the fluid’s chemical and physical properties flow regime, or variations in flow velocity profile. Fluid
mass flow rate and fluid density are independently determined by
measuring the relative motion and frequency of the flow-sensitive elements.
Applications
•tHighly corrosive chemicals
• CMP slurries or solutions containing solid contents and/or bubbles
• Pure water or ultra high purity chemicals
• Fluids with varying density or viscosity
