When to choose Emerson

When you need datasheet-grade Coriolis (Micro Motion Elite, F-Series, ELITE Plus) for custody transfer or high-accuracy mass flow, when standardising on Rosemount across a brownfield Emerson plant, or when ultrasonic custody transfer for crude / natural gas / NGL pipelines is on the table (Daniel 3410, 3415).

Emerson at a glance

Emerson Automation Solutions is the largest single flow-measurement brand by installed base in oil & gas, chemicals and pharma. Three brands sit under the parent umbrella and together cover essentially every primary flow technology:

  • Micro Motion — Coriolis mass flow and density (since 1977; the original commercial Coriolis manufacturer).
  • Rosemount — electromagnetic, vortex and differential pressure (orifice, Annubar, integrated DP).
  • Daniel — ultrasonic for custody transfer of liquid hydrocarbons and natural gas.

In practice this means a plant standardising on Emerson rarely needs a second flow vendor — the same DeltaV or AMS Device Manager environment configures every meter, and the corporate spec lists tend to be deep on Rosemount / Micro Motion part numbers.

Coriolis — Micro Motion

Micro Motion is the de facto reference for Coriolis. The current ranges to know:

  • Elite CMF / CMFS — the gold standard for custody transfer. Accuracy to ±0.05% of rate on liquid mass; OIML R117, MID and API 5.6 approvals. CMFS is the small-line variant for 1/8" to 1.5" and is the go-to for high-value dosing and chemical injection.
  • F-Series — same architecture in a more compact, drop-in form factor for general process duty. ±0.1% of rate.
  • ELITE Plus CMFHC — for HF acid, custody hydrocarbon mixtures and very high pressure (up to 414 bar) duty.

Pair any of these with the 5700 transmitter for advanced diagnostics (Known Density Verification, Smart Meter Verification, two-phase flow ID).

Electromagnetic — Rosemount

The Rosemount magmeter family covers everything from water utility (8750W, with no batteries / no shutdown) to demanding chemical service (8707 high-signal converter, NSF wetted material options). Highlights:

  • Rosemount 8700M / 8732EM — workhorse mag for industrial water, slurry, conductive process fluids. Accuracy ±0.25% of rate.
  • Rosemount 8750W — water-utility specific, NSF/ANSI 61 / 372 wetted, MID / OIML R49 custody for revenue water.
  • Rosemount 8782 — for slurry and abrasive duty with PFA or polyurethane liner choices.

Vortex — Rosemount 8800

The 8800D is the reference vortex meter for saturated and superheated steam. Reduced-bore (8800R) holds accuracy at lower flow rates where many vortex designs go non-linear. Pair with multivariable temperature/pressure compensation for mass-flow-equivalent steam metering.

Custody-transfer ultrasonic — Daniel

The Daniel 3410 (liquid) and 3415 (gas) ultrasonics are the dominant custody-transfer choice for crude, refined products, NGL pipelines and gas pipelines. They typically operate at ±0.15% of reading under metrological conditions and carry full API MPMS Chapter 5.8 / AGA-9 approvals.

When to choose Emerson on InstruSelect

The selector promotes Emerson when:

  • You are doing custody transfer of hydrocarbons (Daniel ultrasonic or Micro Motion Coriolis on small-line product transfer).
  • You want Coriolis-grade accuracy and density on chemical injection, additive blending, allocation or batching.
  • You are deploying or expanding a DeltaV / PlantWeb plant where AMS asset management is already in place — a Rosemount / Micro Motion stack drops in with no extra integration burden.

For pure water utility duty, Badger Meter or Krohne Waterflux may be more cost-effective; for compact CIP/SIP hygienic duty Endress+Hauser Promass is competitive — see the Coriolis comparison for the full trade-off.

Frequently Asked Questions

Is Micro Motion the same company as Emerson?

Yes. Micro Motion has been part of Emerson Automation Solutions since 1984. It operates as a product brand within Emerson, but commercial, support and quoting flow through Emerson channels.

What is the difference between Micro Motion Elite and F-Series?

Elite (CMF / CMFS) is the metrology-grade product line — quoted ±0.05% of rate on liquid mass and approved for OIML / MID custody transfer. F-Series is the same Coriolis architecture in a more compact installation envelope at a lower price point, quoted ±0.1% of rate. For non-custody process measurement, F-Series is the typical default.

Which Emerson meter is best for steam?

For saturated or superheated steam the Rosemount 8800D vortex with integrated MTA (multivariable temperature, absolute pressure) is the standard Emerson recommendation. For very low-flow steam where vortex goes non-linear, a Micro Motion Coriolis on the condensate return is the alternative.

Does Emerson make a clamp-on ultrasonic?

Yes — the Rosemount 3100 series, but Daniel ultrasonics (3410 / 3415) are inline, full-bore custody-grade. For retrofit clamp-on duty the typical InstruSelect recommendations are Siemens SITRANS FUH / Badger Dynasonics, see the clamp-on vs insertion guide.
