Kofloc Model RK1700 Low-cost Flowmeter

Description

The Kofloc Model RK1700 maintains the fundamental quality of a Japanese-made instrument. It features a tapered glass tube housed in a rigid frame. Unlike the high-end precision models that use non-rotating needles, the RK1700 utilizes a standardized needle valve at the bottom of the unit to keep costs low while still providing functional flow adjustment.

The body is available in either Stainless Steel (SUS316) for corrosive environments or Brass for general-purpose air and water lines. This flexibility allows engineers to specify exactly what they need without over-paying for unnecessary features. Its “block” style design ensures it remains stable when mounted and minimizes the risk of glass breakage in busy industrial settings.

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.
