Kofloc FM01 Vortex Flowmeter

Description

The Kofloc FM01 operates on the principle of the Karman Vortex street. When liquid flows past a columnar “bluff body” inside the meter, regular vortices are generated. The frequency of these vortices is directly proportional to the flow velocity. A specialized piezoelectric sensor detects these vibrations and converts them into a precise flow signal.

Because the FM01 has no moving parts, it is virtually maintenance-free and suffers from very low pressure loss. The use of PPS (Polyphenylene Sulfide) resin for the wetted parts makes the sensor acid and alkali-resistant, allowing it to be used for pure water, chemicals, and industrial wastewater. It is a popular choice for semiconductor manufacturing and LCD production lines where cleanliness and durability are critical.

Kofloc

The natural environment is preserved through the balance of solids, liquids and gases that exist on the earth. However, human civilization has caused pollution that has greatly damaged our environment. The task of the present generation is to restore our environment to its natural healthy state. And this is also the greatest challenge for 21st century science and technology.

KOFLOC's corporate motto is "A Scientific Approach for Fluids." In other words, we create products that scientifically measure and control the balance of liquids and gases. We trust that through our work we are making a contribution to the regeneration of the environment and to the establishment of a prosperous society.
