“The rotameter for use under supply pressure variance”
• Constant flow
KOFLOC Variable Area Flow Meter with Integrated Pressure Regulator MODEL 2504FR SERIES combines RK1400 precision rotameter with MODEL 2204 SERIES precision pressure regulator valve to maintain constant flow under supply pressure variance at the inlet.
• 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 2204 SERIES Pressure Regulator
KOFLOC 2204 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 downstream, under varying supply pressure upstream.
• Wide range
KOFLOC Variable Area Flow Meter with Integrated Pressure Regulator MODEL 2504FR SERIES is particularly suited for small to medium flow ranges, offering accurate reading and precise flow control even under varying supply pressure.
• 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 inprecision control of minute flow.
• Steel/Aluminum &Brass fittings
The fittings are available in either SUS316 stainless steel or aluminum-brass with respective O-rings of Viton® for SUS316 and NBR for aluminum-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.
