Kofloc Resin Flow Meter with Reed Switch Model RK20T-RSW SERIES

Description

The Kofloc RK20T-RSW Series adds a layer of “intelligence” to standard manual flow monitoring. By incorporating a magnetic float and a vertically adjustable Reed Switch, the unit acts as both a visual flow meter and a flow switch. When the float reaches the position of the reed switch, it triggers a contact signal (Normally Open or Normally Closed), which can be used to activate an external alarm, shut down a pump, or alert a PLC system. Constructed from reinforced engineering resin, the RK20T-RSW is designed for durability in industrial environments while remaining much lighter and more affordable than stainless steel equivalents. It includes a built-in needle valve for manual flow adjustment, allowing users to dial in the exact flow rate and then set the alarm point accordingly. Whether you are monitoring cooling water for an induction furnace or verifying air flow for an environmental analyzer, the RK20T-RSW provides a reliable, “two-in-one” solution for measurement and process safety.

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.
