Kofloc RK4400 Series Precision Flow Meter for Pressure Regulator has been designed especially for connection to precision pressure regulators and is widely used for cylinder regulators.
Descriptions of Kofloc MODEL RK4400
An area flow meter has a float in a conical cylinder (tapered tube) with a larger end in the upper section and a smaller end in the lower section. The float moves up and down according to the intensity of the flow, and the position at which the float balances indicates the flow rate. Not only simple flow meters that merely measure the flow rate but also flow meters with a valve for flow control, flow meters with a load pressure fluctuation type flow controller, flow meters with a supply pressure fluctuation type flow controller, and flow meters with an alarm switch are available.
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 absorption of constituent
- gas and minimize generation of other types of gas from the parts.
