The compact rugged OG5 oval geared flow meter is designed to give high performance with a low cost of ownership.It has a standard flow range from 0.5 to 100 L/min on 30 cSt oil and 4 to 100 L/min on water like liquids. It can have totally non-metallic wetted components, PEEK™, ceramic and an elastomer which makes this the ideal choice for the metering of aggressive chemicals. The standard inlet and outlet are 1' female threads. For OEM use alternatives, including manifold mountings, are available. The standard model is 316 St St with Viton® 'O' ring seal. At the heart of the OG5 oval geared flow meter are a pair of toothed oval gears one of which contains chemically resistant magnets. Rotation is detected through the chamber wall by a Hall Effect detector or a reed switch giving approximately 78 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.
