Emerson Micro Motion ELITE CMF Series Coriolis Flow and Density Meter

Overview: Peak Performance Coriolis Measurement

The Emerson Micro Motion ELITE CMF Series is a peak performance Coriolis flow and density meter delivering unmatched measurement performance for liquid, gas, and slurry applications, combining industry-leading accuracy, auditable reliability, broad application coverage, and seamless system integration. Designed for demanding process conditions including entrained gas and multiphase flow, ELITE meters provide highly accurate mass flow, density, volume, and temperature measurement in a single device across an exceptionally broad operating envelope.

With fast quotation turnaround and technical support, Seven Star LLC sources and supplies the ELITE CMF Coriolis flowmeter to refineries, LNG facilities, and chemical plants across Oman and the wider GCC. Because ELITE meter configuration spans multiple sizes, materials, and transmitter options, Seven Star LLC helps engineering teams specify the correct sensor and transmitter combination for each custody transfer, process control, or specialty application.

Measurement Principle

Coriolis flow meters are multi-variable devices providing direct measurement of mass flow, density, and temperature for liquids, slurries, and gases, based on the principle that inertia created by fluid flow causes the meter tubes to twist proportional to mass flow rate. Because this measurement is direct rather than inferred, the ELITE CMF delivers accurate mass flow, volume flow, and density readings without needing separate temperature or pressure compensation instruments.

Smart Meter Verification allows real-time, in-process measurement integrity assurance without process interruption – checking meter health in fewer than 90 seconds and providing auditable confirmation of measurement accuracy for regulatory or custody transfer purposes. Real-time indication of multi-phase flow events and diagnostics for performance under entrained gas and batching from empty applications give operators direct visibility into process conditions that would otherwise silently degrade a conventional flowmeter’s accuracy.

Engineering Design of the ELITE CMF

The ELITE CMF300M achieves mass flow accuracy of ±0.10% of rate (standard, liquid) with an optional ±0.05%, density accuracy of ±0.0005 g/cm3 (standard) with an optional ±0.0002 g/cm3, and covers the widest process-measurement range in its class: -454°F to 800°F (-270°C to 426°C) and pressures up to 6,000 psig (414 barg). This range extends the ELITE platform across cryogenic LNG service, high-pressure chemical injection, and high-temperature process applications within a single meter family.

The ELITE platform pairs with a range of transmitters – from the single-variable 1700 field-mount unit through the multivariable 2700, 3500, and 5700 transmitters – offering integral or remote mounting, WirelessHART connectivity, up to 5 fully configurable I/O channels, and a data historian for capturing short- and long-term process event insight. Meter approvals span CSA, ATEX, NEPSI, IECEx, IP66/67, SIL2 and SIL3, marine, and custody transfer certifications, with material options including 316L and 304L stainless steel, C22 nickel alloy, and super duplex for compatibility with demanding process media.

Key Features

The Emerson Micro Motion ELITE CMF Series delivers industry-leading Coriolis flow and density measurement. Key characteristics include:

• Direct mass flow, density, volume, and temperature measurement in a single meter.
• Mass flow accuracy of ±0.10% of rate (standard); ±0.05% optional.
• Smart Meter Verification: real-time, in-process integrity checks in under 90 seconds.
• Operating range from -454°F to 800°F and pressures up to 6,000 psig.
• SIL2 and SIL3 certification with CSA, ATEX, NEPSI, IECEx, and custody transfer approvals.
• Multiple transmitter options with WirelessHART, up to 5 I/O channels, and data historian.
• Material options: 316L/304L stainless steel, C22 nickel alloy, super duplex.

Industrial Applications

The ELITE CMF is deployed across custody transfer stations, process control loops, batching and blending systems, loading and unloading terminals, cryogenic LNG service, hygienic applications, and high-pressure chemical injection. Its wide operating envelope allows a single meter platform to serve applications ranging from steam methane reforming and high-pressure hydrogen dispensing to LNG custody transfer, reducing the number of distinct flow measurement technologies a plant needs to standardize on.

Seven Star LLC supports refinery instrumentation teams, LNG facility operators, and chemical plant engineers across Oman, Muscat, Sohar, and the broader GCC region with sourcing of Emerson Micro Motion ELITE CMF Coriolis meters, helping projects achieve accurate, auditable multi-variable flow measurement.

Technical Specifications

The table below summarizes representative specifications of the Emerson Micro Motion ELITE CMF Series as supplied by Seven Star LLC.

Sensor Sizing and Process Connections

The Emerson Micro Motion ELITE CMF Series spans an unusually wide sizing range for a single sensor family, from the CMF010 at 0.1 in / DN2 with a nominal flow rate near 93.5 kg/h, through the CMF100 (DN25), CMF200 (DN50) and CMF300 (DN80), up to the CMF400 covering DN100–150. Above that, the high-capacity CMFHC variants extend the same platform to DN150–200, DN200–250 and DN250–300, with the largest reaching nominal flow rates in the region of 3,266,000 kg/h — enough for main-line loading and terminal duties that would previously have required a turbine or ultrasonic meter run. Process connection options include ASME B16.5 and EN 1092-1 weld-neck flanges, JIS B2220 raised-face flanges, O-ring face seal fittings and hygienic Tri-Clamp compatible connections.

Repeatability, Gas Performance and Secondary Containment

Alongside headline accuracy, the figure that governs control-loop and proving behaviour is repeatability. The ELITE CMF achieves ±0.025% of rate on liquid mass and volume flow in its premium specification and ±0.05% of rate as standard, with density repeatability of 0.1 kg/m³ and temperature repeatability of 0.2°C. On gas service the meter is specified at ±0.25% of rate as standard, improving to ±0.1% of reference once a piecewise linearisation adjustment has been applied from a gas calibration. Each sensor also carries a pressure-rated outer case acting as secondary containment, and where process pressure could exceed the case burst rating Emerson specifies a rupture disc. The Zero Verification tool allows technicians to confirm whether the stored zero remains valid before deciding to re-zero, avoiding unnecessary line shutdowns during commissioning and routine checks of the Emerson Micro Motion ELITE CMF Series.
