In multi-product chemical plants, standard non-drainable sensors leave process fluid trapped in tube bends, leading to batch contamination and excessive solvent usage. The CMFS150M features a self-draining S-Series curved tube design. When installed vertically with downward flow, gravity completely clears process fluids between batches—saving thousands in solvent flushing cycles and stopping product cross-contamination.
Entrained gas bubbles cause conventional Coriolis meters to stall or report severe measurement drift. Equipped with MVD (Multi-Variable Digital) processing technology, the CMFS150M maintains continuous sensor vibration even during aeration events or fluid flashing. This delivers stable mass flow readings in blending skids, unloading docks, and volatile solvent lines.
Removing a 1.5-inch flowmeter for bench calibration halts plant throughput and creates flange leak risks. Smart Meter Verification (SMV) enables maintenance personnel to run a 90-second structural health audit on the sensor drive circuit and pick-off coils directly from the control room. It fulfills ISO 9001 compliance and SIL 2/3 safety requirements without interrupting fluid transport.
| Evaluation Metric | Micro Motion CMFS150M (1.5") | Legacy Standard U-Tube Meters | Differential Pressure / Turbine Meters |
|---|---|---|---|
| Sensor Footprint | Compact S-Series (Short face-to-face) | Large footprint (Requires pipeline rework) | Compact body, but requires 10-20 DN pipe runs |
| Drainability | 100% Gravity Drainable (Vertical) | Traps fluid in lower U-bend | Variable (Varies by impulse line setup) |

| Density Measurement | Direct (±0.0005 g/cm³) | Direct (±0.001 g/cm³) | External density transmitter required |
| In-Line Health Check | Smart Meter Verification (<90s) | Requires bench removal | Mechanical inspection or bench calibration |
| Upstream Straight Run | 0 DN | 0 DN | 10 to 20 DN upstream required |
Q: Why choose the CMFS150M over the CMFS150H model for process skids?
A: The CMFS150M uses 316L Stainless Steel wetted parts, making it the cost-effective, standard choice for general solvents, hydrocarbons, and non-corrosive chemicals. The CMFS150H uses Nickel Alloy C22 construction specifically for highly aggressive acids, wet chlorine, or corrosive chemical dosing.
Q: Is the CMFS150M certified for Fiscal Custody Transfer?
A: Yes. The CMFS150M holds international custody transfer approvals, including MID, OIML R117, and NTEP. Combined with its SIL 2/3 safety integrity rating, it is widely installed in terminal loading skids and high-value fluid transfer systems.
Q: Can the CMFS150M be installed directly after a pump or control valve?
A: Yes. Micro Motion Coriolis meters are completely immune to upstream flow profile disturbances and vibration. You can bolt the CMFS150M with 0 DN straight pipe runs directly after elbows, reducers, or pumps. Looking for other transmitter options or spare parts from the same brand?
