Precision Flow Meter for Pressure Regulator (for Cylinder Regulator)
MODEL RK4400 SERIES
The KOFLOC RK4400 Flowmeter Regulator
KOFLOC RK4400 flow gauge meter has been designed especially for connection to precision pressure regulators and is widely used for cylinder regulators.
Features
- The precision needle valve Model 2412 is used for easy, fine adjustment of flow.
- The flow meter tube made by high-precision molding ensures excellent stability and repeatability even if it is inclined.
- The material, cleaning method, and assembly are carefully designed for the use of high-purity, high-price standard gases so as to eliminate waste losses, reduce the absorption of constituent gas and minimize the generation of other types of gas from the parts.
- For cylinder regulators
- For line regulators
