Kofloc EX-250S Digital Mass Flow Controller

Digital mass flow device which is adopted the own developed both stable high speed thermal sensor and small proportional solenoid valve and is realized high accuracy and quick response with RS 485 communication in spite of compact.


In comparison with the conventional mechanical products, the mass flow measurement/control technology used in a mass flow meter and controller extracts electrical signals from the flow without significantly influencing the temperature or pressure, thus permitting sophisticated flow measurement and control.

The technology is widely used for manufacturing semiconductors, liquid crystal, optical fibers and other electronic devices, gas supply for fuel cells, and fuel gas control for burners, foods, biotechnology, as well as for experimental facilities and production/inspection systems in many other industries.




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.
