Kofloc Mass Flow Controllers Model HFM-200W/LS SERIES

Description

The Kofloc Model HFM-200W/LS Series addresses the unique challenges of measuring high-volume gas streams where traditional meters would cause excessive pressure loss. By employing a laminar flow element (LFE) bypass system, the HFM-200W/LS diverts only a small fraction of the total flow through the high-precision thermal sensor, while the bulk of the gas passes through a low-resistance main channel. This allows for measurement capacities up to 15,000 SLM while maintaining the system’s energy efficiency and pressure integrity.

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.
