Flow Meter with Precision Needle Valve
MODEL RK1250 SERIES
 
This is a flow meter for device incorporation with the KOFLOC RK1200 design renewed. It is a float type flow meter with a high-grade valve, having a combination of a high-precision float type flow meter and a needle valve capable of accurate flow control. It is a flow meter most suitable for minute-flow instrumentation control.

Features
Capable of ultra-minute flow control
Capable of response to a wide range from an ultra-minut flow of 0.5 ML/MIN to a flow of 30 L/MIN.
Using precision needle valve
By specifying a maximum flow and normal supply pressure, the effective rotation speed of the needle valve can be utilized up to maximum.
(Minute flow control is possible.)
Wide variations
The available total lengths of the flow meter are 126, 156, 206, and 256 mm, which can be selected according to its purpose.
Two types (upper and lower parts) of valve.
Available needle valves are the following two, lower and upper needle valves. Use these valves according to their purpose.
Usable for water
Flow Meters for water flow of 1 L/MIN or less are also manufactured.
