Kofloc HFM-301 SERIES Mass Flow Controllers

Description

The Kofloc Model HFM-301 Series is engineered for precision monitoring in dynamic gas environments. While standard mass flow meters often suffer from “lag” during flow transitions, the HFM-301 utilizes a newly refined bridge-type thermal mass flow sensor and digital signal processing to provide a stable reading in < $\leq 1$ second. This makes it an essential tool for detecting rapid fluctuations in gas lines that slower meters might miss.

A Mass Flow Controller (MFC) is a device used to precisely regulate and control gas mass flow in various industrial and laboratory processes. Unlike conventional flow meters, which only measure velocity or volume, an MFC can both measure and regulate gas flow based on mass, resulting in much more accurate results—especially in applications that require tight and consistent control, such as the semiconductor, pharmaceutical, chemical, and gas analysis 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.
