Gemini Differential Pressure Flow Meter Superior Performance. Rugged Design. Preso® Gemini The Preso Gemini Differential Pressure Flow Meter by Badger Meter has a cone-shaped element which shapes the flow profile ahead of the differential pressure (DP) measurement port without impacting the flow against a sharp surface, creating an extremely stable signal for measurement with minimal wear on the cone edge. How the Gemini Measures Differential Pressure The Gemini differential pressure meter utilizes the center element to straighten the flow and create an ideal dynamic which allows differential pressure technology to be used in a unique way providing extensive flexibility in a wide variety of applications. • Precise accuracy and repeatability • Cost effective • Wide variety of fluids • Little or no straight run piping requirements • No additional flow conditioning devices needed • Low maintenance and long life • No moving parts • Wide flow range • Low head loss Specifications 2 Applications Liquids, steam, air and industrial gases Pipe Sizes 1.0 inch (13 mm) and larger Repeatability ± 0.1% or better Flow Range 10:1 and greater Accuracy ± 0.5% of actual flow Standard Beta Ratio 0.40…0.80, special betas available Permanent Pressure Loss Varies with beta ratio and DP Installation Piping Requirements Typically 0…3 diameters upstream and 0…1 diameters downstream of the cone are required, depending on fittings or valves in the adjacent pipeline Construction Materials 316L stainless steel, carbon steel, other materials on request End Fittings Threaded (NPT), flange, wafer, socket, and butt weld Approvals CRN Gemini Software and Accessories Preso Calculation Software. PresoCalc, a free engineering calculator available from Badger Meter, can help customers properly size the Gemini meter for their system or help with sizing for any DP meter project. Our technical service group is available to assist customers in using this software. Differential Accessories Badger Meter offers a wide variety of technologies to best measure and track system parameters. Gemini can be partnered with an extensive range of DP transmitters including Foxboro, Azbil and Honeywell. Badger Meter also offers a complete flow metering solution by pairing the Gemini with our in-house flow computers and totalizers.
