Kofloc RK1700 Variable Area Flowmeter

The Kofloc Model RK1700 Variable Area Flowmeter is a compact, cost-effective solution for general industrial gas measurement. By utilizing a simplified block design and standardized components, Kofloc offers this model with exceptionally short lead times (often 1 week). It features a durable SUS316 Stainless Steel body and an integrated needle valve, making it a reliable “workhorse” for gas purging, simple mixing, and equipment embedding.

Description

The RK1700 Series centers on reducing complexity to provide a high-value industrial tool. Unlike higher-end models that use expensive non-rotating needle valves, the RK1700 employs a simplified bottom-mounted needle valve that provides functional, smooth adjustment for standard applications.

The wetted parts are made of SUS316 and Pyrex glass, ensuring that even at its “low-cost” positioning, it remains resistant to corrosion and suitable for professional environments. It is calibrated exclusively for common gases—Air, N_2, and O_2—which allows for standardized production and immediate delivery. While it has a slightly wider accuracy margin ($\pm$7% F.S.) than precision models, it provides the robust mechanical stability Kofloc is known for

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

  • Highly Economical: Designed to minimize capital expenditure for large-scale industrial projects.
  • Short Delivery Time: Standardized configurations allow for shipping within approximately one week.
  • SUS316 Construction: High-grade stainless steel body as standard for superior durability.
  • Compact Footprint: Miniature block design is perfect for installation in tight gas panels or OEM machinery.
