KOFLOC Precision Variable Area Flow Meter for Gas Mixing MODEL RK120XM SERIES
Quick Review
• 2 to 4 tubes in one unit
The KOFLOC Precision Variable Area Flow Meter for Gas Mixing MODEL RK120XM SERIES combines 2 to 4 RK1200 precision flow-tubes that make it simpler to measure and control of multiple flow range or gases and avoid clutter.
• KOFLOC RK1200 SERIES High Precision Variable Area Flowmeter
KOFLOC RK1200 SERIES High Precision Variable Area Flow Meter is a high-grade rotameter especially suited for measurement and control of minute flow, with an industry reputation of being one of the best analog devices.
• KOFLOC 2412 SERIES Precision Needle Valve
KOFLOC 2412 SERIES Non-Rotating Precision Needle valve allows precise and easy flow control of minute amounts of gases and liquids. The internal mechanism converts rotating movement into stable linear movements with minimal vibrations. The needle and orifice has a thermal compensating structure (US P.A.F.) of 0.3%/?C (15?C to 35?C).
• Top/Bottom valve position
The KOFLOC Precision Variable Area Flow Meter for Gas Mixing MODEL RK120XM 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 Precision Variable Area Flow Meter for Gas Mixing MODEL RK120XM 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 VitonR for SUS316 and NBR for brass fittings. The flow tube is made of PyrexR.
• 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 Precision Variable Area Flow Meter for Gas Mixing MODEL RK120XM 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 KalrezR, PerfluoroR or fluorocarbon resin fittings
