Kofloc Model RK 1500 Flow Meters and Controllers for Liquid

The Kofloc Model RK1500 Flow Meter and Controller for Liquid is engineered for applications where reading precision is paramount. By utilizing an elongated 150mm glass tube, the RK1500 provides a significantly expanded scale compared to standard meters, allowing operators to monitor and control liquid flow rates with much finer increments.

Equipped with Kofloc’s signature precision needle valve and a rugged SUS316 body, the RK1500 is the ideal choice for high-end laboratory setups and industrial pilot plants that demand superior readability for water and chemical fluids.

Description

The Kofloc Model RK1500 is defined by its “High Resolution” capability. In flow measurement, the length of the scale directly impacts the user’s ability to detect small changes in flow. The RK1500’s longer profile allows for a more gradual taper in the Pyrex glass tube, which results in a highly linear and easy-to-read scale.

For liquid applications, the RK1500 is standardly calibrated for Water ($H_2O$). It incorporates a high-performance needle valve that can be positioned at either the inlet or outlet. This valve is a “non-rotating” type, meaning the needle moves strictly up and down without spinning against the valve seat. This prevents the mechanical wear and “shredding” often found in cheaper valves, ensuring that your liquid flow setting remains stable over months of continuous operation.

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.

Features

  • 150mm High-Resolution Scale: Longer glass tube for precise flow setting and superior readability.
