The Micro Motion ELITE CMFS015M (DN3) is engineered for chemical process engineers and skid builders who need zero-drift metering in micro-flow dosing, catalyst injection, and pilot plant systems. It eliminates the revenue-draining issues common with traditional non-drainable micro-flow meters: fluid entrapment, expensive solvent flushing cycles, and batch-to-batch contamination.

In high-cost additive or catalyst injection lines, standard U-tube meters leave behind fluid in sensor low points. Cleaning them requires gallons of flushing solvent and hours of line purging. The CMFS015M features a single, continuous, self-draining S-Series curved tube design. Installed vertically, gravity completely evacuates residual process fluid between batches—saving thousands in raw material waste and preventing batch degradation during product transitions.
Standard differential pressure (DP) and thermal meters drift whenever line pressure or gas temperature fluctuates, requiring complex external compensation loops. The CMFS015M directly measures mass flow without extra pressure transmitters or temperature calculations. Operating at line pressures up to 1,812 psig (125 barg), it delivers stable $\pm 0.25\%$ gas mass flow accuracy for specialty gas blending and toxic gas injection.

Removing a meter from a running line for annual zero-check calibration halts production and risks joint leaks. Equipped with Smart Meter Verification (SMV), the CMFS015M lets maintenance technicians run a full structural health check of the drive circuit and sensor tubes in under 90 seconds—right from the control room or field transmitter—without stopping the pump or interrupting active flow.

Q: Why choose the CMFS015M over the legacy CMF010 model for chemical skids?
A: The CMFS015M uses a compact, self-draining S-Series geometry. Unlike the legacy CMF010 which traps fluid at the bottom of its U-tube bend, the CMFS015M empties completely when mounted vertically. This prevents fluid stagnation, reduces flushing solvent usage, and speeds up product changeovers.
Q: Is 316L Stainless Steel safe for my acid dosing process?
A: 316L Stainless Steel works well for general chemical additives, hydrocarbons, and solvents. If your process handles highly aggressive media like hydrochloric acid, wet chlorine, or ferric chloride, we supply the CMFS015M with Nickel Alloy C22 wetted parts to resist pitting and stress corrosion cracking.
Q: Does the CMFS015M require upstream or downstream straight pipe runs?
A: No. Micro Motion Coriolis meters are completely immune to flow profile disturbances. You can bolt the CMFS015M directly to an elbow, pump outlet, or control valve in tight skid environments without sacrificing accuracy.
