Kofloc Model 3200 Mass Flow Controller

Description

The Kofloc Model 3200 is designed to provide “big performance in a small package.” By utilizing advanced micro-machining and miniaturized electronics, Kofloc has managed to shrink the footprint of a standard mass flow controller without sacrificing the stability of its thermal mass flow technology.

Because it measures mass directly, the Model 3200 is unaffected by fluctuations in ambient temperature or line pressure. The internal closed-loop circuitry compares the actual flow against the user’s set-point signal and adjusts the internal valve in real-time. This ensures that the gas flow remains exactly where it needs to be, providing superior process consistency. Its small form factor makes it particularly popular with OEM manufacturers who need to fit multiple gas lines into a single, high-density manifold or instrument chassis.

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.
