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
