Kofloc Model RK120XM Flow Meter for Gas Mixing

Description

The Kofloc Model RK120XM Flow Meter for Gas Mixing streamlines the process of gas blending. Instead of relying on complex electronic mass flow controllers or disparate piping arrangements, this unit provides a mechanical, easy-to-read solution. It features two or three precision glass tube flow meters mounted side-by-side, feeding into a common mixing manifold.

Each gas line has its own dedicated control valve, allowing the operator to adjust the flow rate of individual gases to achieve the desired mixing ratio. The high-precision borosilicate glass tubes provide clear visual feedback, ensuring that the mixture remains consistent throughout the operation. By producing gas mixtures on demand, facilities can significantly reduce operational costs and increase process flexibility. The unit is robustly constructed to withstand industrial environments while maintaining laboratory-grade accuracy.

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.
