Kofloc Model 3760 Standaid Mass Flow Meter

Description

The Kofloc Model 3760 utilizes a sophisticated thermal mass flow sensor. The principle involves a capillary tube with a heating element; as gas passes through, heat is transferred in proportion to the mass of the gas molecules. This data is then converted into a highly linear analog signal.

The 3760 series is designed for users who require a robust, standardized sensor that can be integrated into a larger system. It does not feature a built-in display, making it more compact and vibration-resistant than digital models. Instead, it provides a 0–5V DC output that is easily read by PLCs, data loggers, or remote readout units. Its Stainless Steel (SUS316) construction ensures compatibility with a wide variety of non-corrosive gases, providing the “standard” of reliability that Kofloc is famous for worldwide.

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.
