Kofloc Flow Meters with Photosensor Model RK1812/RK1814 SERIES

The Kofloc RK1812 Series (and its compact variant RK1814) represents the next generation of flow alarm technology.

Description

The Kofloc RK1812 Series (and its compact variant RK1814) represents the next generation of flow alarm technology. While magnetic reed switches are common, they can sometimes be affected by external magnetic fields or “sticking” over long periods. The RK1812/1814 utilizes a thru-beam photosensor that detects the physical interruption of light by the float. This results in an incredibly precise and repeatable alarm trigger that is immune to electromagnetic interference (EMI).

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.
