Kofloc RK1250 Series Flow meter is a completely renewed model of the existing KOFLOC RK1200, designed as a flow meter 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.
Kofloc RK1250 Series 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 a 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 flow also possible
- Measurement and control of water flow not exceeding 1l/min are also possible.
Kofloc RK1250 Series 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
