Oval gear flow meter OG4

for liquidsDN20 - 3/4"in-line

The compact rugged OG4 oval gear flowmeter – a swept volume flow measurement device, is designed to give high performance with a low cost of ownership. It has a standard flow range from 0.25 to 50 L/min on 30 cSt oil and 2.5 to 50 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 ¾' 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 rugged OG4, swept volume oval gear flowmeter 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 or a reed switch giving approximately 115 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.
