Kofloc Model 2504FR Flow Meter with Flow Controller

Description

The Kofloc Model 2504FR is engineered for precision. In most gas delivery systems, as a supply cylinder empties or a compressor cycles, the flow rate will naturally drift. The 2504FR solves this mechanically. It features an internal differential pressure regulator that automatically compensates for changes in inlet pressure, keeping the pressure drop across the needle valve perfectly stable.

As a result, the float in the glass tube stays exactly where you set it. Because it is purely mechanical, the Kofloc Model 2504FR Flow Meter with Flow Controller requires no electrical power, making it intrinsically safe and incredibly reliable for long-term, continuous operation. The high-grade finish and robust SUS316 or Brass construction ensure it meets the aesthetic and functional standards of both high-end laboratories and rugged industrial gas panels.

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.
