Kofloc FM31 (TEFLON/PFA) Vortex Flow Meter for Liquids

The Kofloc FM31 (TEFLON/PFA) Vortex Flow Meter for Liquids is a high-performance flow measurement solution specifically designed for high-purity and highly corrosive fluid applications. By utilizing the Karman vortex principle, this meter provides accurate, reliable, and maintenance-free measurement without any moving parts.

Constructed with premium PFA/Teflon wetted parts, the Kofloc FM31 (TEFLON/PFA) Vortex Flow Meter for Liquids ensures maximum compatibility with aggressive chemicals and prevents contamination in ultrapure water systems, making it the industry standard for semiconductor and chemical processing.

Description

The Kofloc FM31 (TEFLON/PFA) Vortex Flow Meter for Liquids operates on the advanced principle of vortex shedding. As liquid flows past a shedder bar within the meter, it creates a series of vortices at a frequency proportional to the flow velocity. Because there are no mechanical rotors or bearings to wear out, the FM31 offers exceptional long-term stability and a significantly lower total cost of ownership compared to traditional mechanical meters.

The core strength of this instrument lies in its material integrity. Every component in contact with the fluid is made from PFA, a fluorocarbon resin known for its near-universal chemical resistance and smooth surface finish that prevents particle entrapment. The Kofloc FM31 (TEFLON/PFA) Vortex Flow Meter for Liquids is not only resistant to acids and alkalis but is also optimized for noise resistance, ensuring that your flow data remains accurate even in electronically noisy industrial environments.
