    Flowmeter With Precision Needle Valve (for Accurate Flow Control)
    MODEL RK1200 SERIES

    This is a grade high precision float type flowmeter com-bined with a needle valve capable of very accurate flow control. It is ideal for measurement and control of minute flows.

    Features
    - Capable of controlling ultra-minute flows

    - A needle valve incorporated to maximize precision control of flows

    - Two types of valve arrangement available:at the top or bottom of the meter at the user's choice

    - Wide variations

     Applications

    - For integration into your equipment panel

    - For gas devices to be used on the semiconductor manufacturing site

    - For biotechnology industries

    - For vacuum line control
