KOFLOC Multiple-Tube Precision Variable Area Flow Meter with Needle Valves MODEL RK140X SERIES
Quick Review
• 2 to 4 tubes in one unit
The KOFLOC Multiple-Tube Precision Variable Area Flow Meter with Needle Valves MODEL RK140X SERIES combines 2 to 4 RK1400 precision flow-tubes optimized for gas mixing applications.
• KOFLOC RK1400 SERIES High Precision Variable Area Flowmeter
The KOFLOC High Precision Variable Area Flow Meter MODEL RK1400 SERIES employs a flow-tube manufactured with a proprietary glass molding technique and super-precision spherical float. This is a premium variable area flow meter that counters the perception of rotameter as being only good for a rough estimate.
• Top/Bottom valve position
The KOFLOC Multiple-Tube Precision Variable Area Flow Meter with Needle Valves MODEL RK140X SERIES comes with either the top (outlet) valve or the bottom (inlet) valve. There are many issues to consider in choosing the right valve position. Contact Kofloc for more information.
• KOFLOC Dependability
KOFLOC has 60 years of experience in manufacturing precision flow instruments. KOFLOC products, both standard and off-catalog custom items are well received throughout Japan as the name that manifests confidence. KOFLOC, the fluid expert, is the name professionals trust in precision control of minute flow.
• Wide flow range coverage
The KOFLOC Multiple-Tube Precision Variable Area Flow Meter with Needle Valves MODEL RK140X SERIES covers small flow ranges from 0.5 ml/min to 3 l/min to medium range of 10 ml/min to 100 l/min.
• Steel/Brass fittings
The fittings are available in either SUS316 stainless steel or brass with respective O-rings of Viton® for SUS316 and NBR for brass fittings. The flow tube is made of Pyrex®.
• Tri-flat & rib-guide flow-tubes
KOFLOC leads the industry in tri-flat flow-tube (for flows between 5 ml/min to 500 ml/min) production with superior precision. The rib-guide flow-tubes are used for medium range flows between 1 l/min and 50 l/min.
The KOFLOC Multiple-Tube Precision Variable Area Flow Meter with Needle Valves MODEL RK140X SERIES can only be used for the following gases.
Medium (gases): Actual gas calibration is available for the gas listed
Air, Argon: Ar, Carbon dioxide: CO2, Helium: He, Hydrogen: H2, Nitrogen: N2, Oxygen: O2
N2 equivalent conversion factor (CF) is used for other gases. Contact KOFLOC for the availability of actual gas calibration.
Customization and Optional services
• Optional flow-tubes with ±1% accuracy
• Optional Kalrez®, Perfluoro® or fluorocarbon resin fittings
