OG7 - 500 L/MIN OVAL GEAR FLOW METER
|
The rugged OG7 oval gear flowmeter is designed to give high performance with a low cost of ownership. It has a standard flow range from 5.0 to 500 L/Min on 30 Cstk oil and 20 to 500 L/min on water like liquids. The standard inlet and outlet are 2” BSP female threads. For OEM use alternatives, including manifold and flange mountings, are available. The standard model is 316 St St with Viton™ ‘O’ ring seal. For hazardous areas either the Namur sensor or the reed switch (simple appa-ratus) may be used.

At the heart of the meter are a pair of toothed oval gears one of which contains chemically resistant magnets, the gears rotate freely on robust bearings. Rotation is detected through the chamber wall by a Hall effect detector, Na-mur sensor or a reed switch giving approxi-mately 15 pulses per litre passed. The output is an NPN pulse or a voltage free contact closure either of which is readily interfaced with most elec-tronic display or recording de-vices. This combination of mate-rials and technology ensures a long life product with reliable, ac-curate operation throughout.
