Emerson Process Management has added the Micro Motion Elite CMFS sensor platform to its line of Coriolis flow meters to deliver precise measurement to smaller line sizes (pipelines less than 2 inches or DN50). The new sensor platform expands the Elite family of flow meters, whose functionality, line size breadth, accuracy, and flexibility make them suitable for a wide range of real-world applications.
With nine distinct sensor sizes in three compact footprints, from 1 mm to 50 mm in nominal diameter lines sizes (1/12" to 2"), this meter delivers ±0.05 percent liquid flow mass and volume accuracy, ±0.25 percent gas accuracy, and ±0.0002 g/cc density accuracy for flow rates of 0.04 lb/min to 1,980 lb/min (1kg/h to 54,000kg/h).
The new platform features a compact, light-weight and fully drainable design. The meter offers high rangeability with a turndown ratio up to 30:1. In addition, the meters provide a flow measurement platform for repeatable measurement in transient two-phase flow conditions.
The platform was designed to serve a wide range of applications, including chemical injection, production blending, process gas solutions and batching operations in a variety of industries. For corrosive and high pressure applications, the meters are available in stainless steel 316L and nickel alloy C22 construction and are rated to 6,000 psi (413 bar). For cryogenic and high-temperature applications, the meter handles process temperatures from -240 degrees C to 204 degrees C (-400 degrees F to +400 degrees F). Optional 316L polished exteriors makes the meters suitable for sanitary, hygienic and offshore installations. In addition, the new meters are 3A and European Hygienic Engineering & Design Group (EHEDG) approved with 15 and 32 Ra surface finish options.
