Flow Meters

The flow meter (area type flow meter) has a float inside a conical cylinder (tapered tube) with the upper end larger than the lower end. The float moves up and down according to the intensity of flow, and the reading taken when the float balances indicates the flow rate. KOFLOC provides flow meters with a valve that can perform both measurement and control of the flow rate, flow meters with an alarm function and many other products.

Flow Meter with Precision Needle Valve MODEL RK1200 SERIES.This is a grade high precision float type flowmeter combined with a needle valve capable of very accurate flow control. It is ideal for measurement and control of minute flows.

■Fluid：
Gas　N₂,Air,H₂,He,Ar,O₂,CO₂ etc.　
Liquid　H₂O
■Flow range：
Gas　5mL/min～100L/min
Liquid　5mL/min～2L/min
■Accuracy：±2%F.S.

High-Pressure Flow Meter MODEL RK1400 SERIES This top-grade high precision, float type area flowmeter is a fruit of KOFLOC's challenge to boost the general perception currently conceived by people of flowmeter of being a "mere yardstick" into a new conception that a flowmeter is a "precision instrument." This flowmeter particularly features its uniquely precision-formed glass tube and ultra-precision ball float that ensures accurate measurements of minute flows to medium flows.
