MODEL RK1250 SERIES
Model RK1250 Series Flowmeter is a completely renewed model of existing KOFLOC RK1200,designed as a flowmeter that can be integrated into the customer's equipment.A happy 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.
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 control 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 1l/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 control
