TECHNICAL PRODUCT DATA SHEET The compact rugged OG4 oval gear flowmeter 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, PTFE encapsulated magnets and elastomer seals which makes this the ideal choice for the metering of aggressive chemicals. The standard inlet and outlet are %” female threads. For OEMs, alternatives are available, including manifold mountings. The standard model is 316 St St with Viton™ ‘O’ ring seal. • Engine test High viscosity liquids OEM equipment Hazardous areas Batching 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 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. • Excellent chemical resistance • Rugged construction • Individual calibration • High viscosity options • No flow conditioning required • Compact meter assembly • Hall, reed switch or Namur sensor • Accuracy 1.0% reading water • Non-metallic option
