The compact rugged OG1 oval gear flowmeter is designed to give high performance with a low cost of ownership.
It has a standard flow range from 0.01 to 1 L/Min on 30 Cstk oil and 0.1 to 1.0 L/min on water like liquids.
It can have totally non-metallic wetted components, PEEK™, ceramic and an elas-tomer which makes this the ideal choice for the metering of aggressive chemicals.
The standard inlet and outlet are ¼” BSP female threads. For OEM use alternatives, including manifold 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 apparatus) 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 2050 pulses per litre passed. The output is an NPN pulse or a voltage free contact closure either of which is readily interfaced with most electronic display or recording devices. This combination of materials and technology ensures a long life product with reliable, accurate operation throughout.
