Kofloc Low Pressure Drop Flow Meter Model RK230 SERIES

Description

The Kofloc RK230 Series is specifically designed to measure large flow rates—up to 1,000 L/min (Air)—while keeping the pressure loss across the meter to an absolute minimum. This is achieved through an expanded internal flow path and a high-transparency tapered tube that allows for a larger float with better aerodynamic stability. The RK230 stands out due to its precision non-rotary needle valve. Unlike standard valves where the stem rotates against the seat (causing wear and particulate generation), the RK230’s valve moves linearly. This ensures a much longer service life and exceptional setting repeatability. The meter is available in Brass or SUS316 Stainless Steel, making it suitable for both inert and corrosive gas service. With its long, 150mm scale, operators can achieve high-resolution readings, making it the definitive choice for main supply lines in factories, laboratories, and large-scale analytical setups.

Kofloc

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.
