KOFLOC Variable Area Flow Meter with Integrated Pressure Regulator MODEL 2503F SERIES
Quick Review
• Constant flow
KOFLOC Variable Area Flow Meter with Integrated Pressure Regulator MODEL 2503F SERIES combines RK1400 precision rotameter with MODEL 2203 SERIES precision pressure regulator valve to maintain constant flow into the secondary system even under varying load pressure at the outlet.
• KOFLOC RK1400 SERIES High Precision Variable Area Flowmeter
KOFLOC RK1400 SERIES High Precision Variable Area Flow Meter 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.
• KOFLOC 2203 SERIES Pressure Regulator
KOFLOC 2203 SERIES Pressure Regulator is a flow control valve for minute flow to maintain constant flow and/or fine flow adjustments. The internal precision needle valve allows precision flow control under varying pressure load at the secondary sub-system, so long as the supply pressure remains constant.
• Wide range
KOFLOC Variable Area Flow Meter with Integrated Pressure Regulator MODEL 2503F SERIES is ideal from small to medium flow ranges, offering accurate reading and precise flow control even under varying pressure load
• 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.
• Flow control system
So long as the supply pressure remains constant, KOFLOC Variable Area Flow Meter with Integrated Pressure Regulator MODEL 2503F SERIES is freed from reading errors induced by pressure variance and can function as a part of a complete flow control system.
• 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.
• 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.
KOFLOC Variable Area Flow Meter with Integrated Pressure Regulator MODEL 2503F 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 2 scales for different gases.
• MODEL 2503FR SRIES for supply pressure variance (pressure deviations at the inlet)
