This top-grade high precision, float type area flowmeter is a fruit of KOFLOC’s challenge to boost the general perception currently conceived by people of flowmeter of being a “mere yardstick” into a new conception that a flowmeter is a “precision instrument.”
This top-grade high precision, float type area flowmeter is a fruit of KOFLOC’s challenge to boost the general perception currently conceived by people of flowmeter of being a “mere yardstick” into a new conception that a flowmeter is a “precision instrument.” This flowmeter particularly features its uniquely precision-formed glass tube and ultraprecision ball float that ensures accurate measurements of minute flows to medium flows.
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.
