Kofloc Model RK1250 Flow Meters and Controllers for Liquid

The Model RK1250 Series Flowmeter is a completely re-newed model of existing KOFLOC RK1200, designed as a flowmeter that can be integrated into the customer’s equip-ment. A combination of a grade high precision float type flowmeter with a needle valve capable of very accurate flow control provides a flowmeter ideal for measurement and control of trace 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.

Features

  • Capable of controlling ultra-minute flows
    Can respond to a wide range of flows from ultra-minute flows of 0.5-3 ML/MIN to flows of 3-30 L/MIN.
  • The incorporated precision needle valve allows a delicate con-trol of flows.
    The effective revolving speed of the needle valve can be maximized by specifying a maximum flow and normal supply pressure.
  • Wide variations
    Four total lengths of the flowmeter are available: 126, 156, 206, and 256 mm, for your selection according to your needs.
  • Two types of valve arrangement
    The needle valve can be laid out either at the top or at the bottom of the meter. Choose the type that best suits your needs.
  • Measurement and control of water flows also possible
    Measurement and control of water flows not exceeding 1 L/MIN are also possible.

Applications

  • For integration into your equipment panel
  • For gas devices to be used on the semiconductor manufac-turing site
  • For biotechnology industries
  • For vacuum line contro
