Kofloc Model RK1450 High Precision Flowmeter

This top-grade high-precision 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.”

Description

This top-grade high-precision 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 ultra-precision ball float.

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

  • Capable of measuring ultra-minute flows
    Can measure a wide range of flows from ultra-minute flows of 0.5-3ML/MIN to flows of 3-30 L/MIN.
  • High precision measurement
    High precision measurement of flows is available up to ±2% of full scale (standard specification) or to ±1% of full scale (optional specification).
  • Wide variations
    A broad range of variations is available in total length, materials of construction, flow rate, pressure, scale, and so forth to meet diverse applications from a variety of fields.
  • Capable of measuring all kinds of gases
    Practically all kinds of gases can be measured, not to mention those standard (Air, N2, O2, H2, He, Ar and CO2).
  • Measurement of water flows also possible
    Measurement of full-scale water flows not exceeding 1 L/MIN is also possible. (Dimensions may vary depending upon the specified maximum flow rate.)

Applications

  • For integration into your equipment panel
  • For flow inspections at laboratory
  • For semiconductor manufacturing equipment
  • For biotechnology industries
