Kofloc Multiple Flow Meter with Needle Valve Model RK 120X Series

Multiple Flow Meter with Needle Valve (for Measurement and Control for Laboratory)

MODEL RK 120X SERIES

This multiple flow meter with a needle valve is made by combining several types of flow meter for controlling various flows in a laboratory. It is designed based on the RK1200, a flow meter with precision needle valve, and has been verified to have outstanding reliability.

Features

•Multiple control of two to four flow meters

Two to four flow meters can be attached to one unit to permit control

of various gases in various flow ranges.

•Various flow ranges

The flow meter can measure a variety of flows ranging from the very

small flow of full-scale 5 ML/MIN to 20 L/MIN.

•High-precision measurement and control

This flow meter is designed based on the precision flow meter RK1200 and permits control of very small flow and high-precision measurement (FS ±2%).

Applications

• Control of multiple components
• Multiple range control
• Flow control in laboratories
