In 2-inch process pipelines, minor flow measurement drift quickly accumulates into tens of thousands of dollars in unmetered inventory. Volumetric meters rely on secondary pressure and temperature transmitters to calculate mass, introducing stacked tolerances whenever line conditions fluctuate.
The Micro Motion CMF200M directly measures mass flow by capturing the Coriolis force exerted by the fluid on its twin curved sensor tubes. Combined with a liquid density accuracy of ±0.0005 g/cm³ (upgradable to ±0.0002 g/cm³), this meter eliminates calculation errors caused by fluid expansion, bubbles, or temperature spikes in storage tanks and loading skids.
Removing a 2-inch Coriolis flow meter from a live line for calibration means halting production, draining pipes, and paying heavy labor costs.
With Emerson’s integrated Smart Meter Verification (SMV), maintenance teams run total structural and electronic integrity checks in less than 90 seconds while the fluid continues to flow. The transmitter evaluates tube stiffness, drive voltage, and zero stability without breaking pipe flanges or interrupting line operations. This allows plants to safely extend physical calibration intervals from annually to every 3 to 5 years without risking compliance audits.
| Selection Criteria | CMF200M 2-Inch Coriolis | 2-Inch Industrial Vortex Flowmeter | 2-Inch Electromagnetic Meter |
| Primary Measurement | Direct Mass Flow, Density, Temp | Volumetric Flow Rate | Volumetric Flow Rate |
| Fluid Capability | Liquids, Gases, Slurries, Viscous | Steam, Clean Gas, Low-viscosity Liquid | Conductive Liquids Only |
| Straight Pipe Run Requirement | 0 DN (No straight run needed) | 10–20 DN Upstream required | 5 DN Upstream required |
| Viscosity & Air Bubble Sensitivity | Immune (Measures pure mass) | High viscosity damps vortex signals | High solids/bubbles cause signal noise |
| Primary Engineering Value | Fiscal custody transfer, precise mass batching | Utility steam headers, simple gas flow | Water, wastewater, basic chemical dosing |
Smart Meter Verification tests the sensor tube's physical stiffness and drive electronics in-line without taking the meter off the pipe. This reduces unnecessary pulls for lab calibrations, saving hours of maintenance labor and process downtime.
316L Stainless Steel is ideal for standard industrial chemicals, water, steam, fuels, and food-grade processes. However, if your application involves wet chlorine, sour gas (H2S), or aggressive acids, consider specifying Hastelloy C-22 or Super-Duplex variants instead.
Yes. Unlike vortex meters that require low viscosity to form vortices, or turbine meters that get clogged, the CMF200M's curved dual-tube design measures mass flow independently of fluid viscosity, Reynolds number, or suspended solid content.
