Flowmeter with Precision Needle Valve (for Accurate Flow Control)

Model RK1250 Series

The model RK1250 Series Flowmeter is a completely renewed model of existing KOFLOC RK1200, designed as a flwometer that can be integrated into the customer's equipment. 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.


  • Capable of controlling untra-minute flows
    Can respond to a wide range of flows from ultra-minute flows of 0.5-3 ML/MIN flows of 3-3 L/MIN

  • The incorporated precision needle valve allows a delicate control of flows
    The effective revolving speed of the needle valve can be maximized by specifying a maximum flow and normal supply pressure

  • 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


  • For integration into your equipment panel
  • For gas devices to be used on the semiconductor manufacturing site
  • For biotechnology industries
  • For vacuum line control
