OG1 Oval Gear Positive Displacement Flow Meters

OG1 Oval Gear Flowmeters

The compact OG1 oval gear liquid flowmeter gives high performance, excellent chemical resistance and has high viscosity options available for liquids above 1000cSt. This oval gear flow sensor has a standard flow range from 0.01 to 1.0 L/min on 30 cSt oil and 0.1 to 1.0 L/min on water-like liquids. With variable high pressure models up to 700 bar in standard 316 Stainless Steel with Viton™ ‘O’ ring seal and a standard ¼” process fitting size, options for non-metallic PEEK materials and sensors suitable for hazardous areas are available. For OEM applications other alternatives are available, including high pressure options and manifold mountings.
