Kofloc Model RK1450 High Precision Flowmeter

The Kofloc Model RK1450 High Precision Flowmeter is a premium variable area flowmeter designed for users who demand the highest levels of accuracy and aesthetic quality.

Description

The Kofloc Model RK1450 High Precision Flowmeter represents the pinnacle of manual flow measurement technology. While standard flowmeters are often sufficient for general utility monitoring, the RK1450 is built for critical applications where minute variations in flow can impact the outcome of an experiment or a manufacturing process.

The heart of the RK1450 is its high-precision borosilicate glass tube. Each tube is manufactured to strict tolerances to ensure an accuracy of ±2% of Full Scale. This precision is complemented by a “non-rotary” needle valve design (in specific configurations) or a high-resolution needle valve that allows for exceptionally smooth and stable adjustment. The meter’s body is available in high-purity Stainless Steel (SUS316) or Brass, featuring a “grade-up” polished finish that is resistant to environmental degradation and perfectly suited for cleanroom or laboratory environments.

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.
