Plant uptime is increased with the maintenance-free design The Annubar sensor is designed to prevent wear and blockage in the pipe. The electronics are the most stable in the industry and allows up to 10 year calibration cycles, providing significant maintenance savings. Energy savings gained through minimal permanent pressure loss The non-constricting design of the Annubar sensor creates minimal blockage in the pipe, which reduces permanent pressure loss. Permanent pressure loss can be converted directly into energy savings in the form of compressor cost for gas, electrical cost for pumping liquids, and fuel costs for generating steam. Industry leading integrated DP flowmeters By integrating pressure transmitter electronics with the Annubar, Rosemount provides the highest performing insertion DP flowmeter. This fully integrated flowmeter eliminates the need for instrument fittings, tubing, valves, adapters, manifolds, and mounting brackets, thereby reducing welding and installation time. Advanced PlantWeb® Functionality Rosemount Annubar flowmeters power PlantWeb through a scalable architecture, advanced diagnostics, and MultiVariable capabilities. This reduces operational and maintenance expenditures while improving throughput and utilities management. Rosemount DP Flow Solutions Annubar Flowmeter Series: Rosemount 3051SFA, 3095MFA, 485, and 285 The state-of-the-art, fifth generation Rosemount 485 Annubar combined with the 3051S or 3095MV MultiVariable transmitter creates an accurate, repeatable and dependable insertion-type flowmeter. The Rosemount 285 provides a commercial product offering for your general purpose applications. Compact Orifice Flowmeter Series: Rosemount 3051SFC, 3095MFC, and 405 Compact Orifice Flowmeters can be installed between existing flanges, up to a Class 600 (PN100) rating. In tight fit applications, Integral Orifice Flowmeter Series: Rosemount 3051SFP, 3095MFP, and 1195 These integral orifice flowmeters eliminate the inaccuracies that become more pronounced in small orifice line installations. The completely assembled, ready to install flowmeters reduce cost and simplify installation. Orifice Plate Primary Element Systems: Rosemount 1495 and 1595 Orifice Plates, 1496 Flange Unions and 1497 Meter Sections A comprehensive offering of orifice plates, flange unions and meter sections that is easy to specify and order. The 1595 Integral mount head allows close coupling to most Rosemount transmitters which provides flowmeter capabilities. 2 a conditioning orifice plate version is available, requiring only two diameters of straight run upstream. Conditioning Orifice provides superior performance in tight fit applications.
