Quick Answer: Emerson Micro Motion Elite Coriolis sensors deliver mass flow accuracy to 0.05 percent and liquid density accuracy to 0.0005 g/cc on many line sizes. Silver Automation Instruments supplies high accuracy Coriolis mass flow meters for DN15 to DN300 process lines with 4-20 mA HART output. Send your flow range in kg/h, pipe size DN, pressure in bar and temperature in °C for a budget price and delivery time.
Emerson Micro Motion Elite series is a reference point for custody transfer and batch control in chemical, oil and gas and food plants. The sensors use a bent or straight tube design with MVD digital processing. For mass flow the base accuracy is 0.05 percent of rate for liquids and 0.25 percent for gas on most line sizes. Repeatability can reach 0.025 percent of rate.
Density accuracy is 0.0005 g/cc for liquids. This performance matters for concentration measurement in caustic dilution, syrup blending and fuel density checks. Temperature output uses a PT100 sensor in the flow tube. Many Elite sensors are rated from -240 °C to 350 °C depending on wetted material and secondary containment. The flow reading does not depend on conductivity in µS/cm so the same meter can handle condensate and concentrated acid.
Elite sensors cover small lines such as DN15 and DN25 for paint dosing and catalyst injection. Mid sized DN50 and DN80 sensors handle reactor feed lines and truck loading. DN100 to DN300 sensors serve offloading skids and seawater desalination brine lines.
Common wetted materials are 316L stainless steel and Hastelloy C-22. High pressure versions can reach 100 bar or more on small line sizes. Process connections include flanges, hygienic tri-clamp and threaded fittings. The housing is stainless steel or aluminium for offshore and tropical sites.
The MVD transmitter allows direct mass flow, volume flow, density and temperature output in one unit. You can order 4-20 mA HART, Modbus RTU, Profibus DP or pulse output. Several units ship with ATEX Zone 1 or IECEx protection for gas group IIB and dust zone 21 if needed. A diesel terminal in Saudi Arabia or a solvent plant in Vietnam often needs that rating.
One issue on real sites is zero drift after vibration or sensor impact. Field calibration with process liquid at operating temperature solves most errors. Most engineers skip static zero checks after installation. In practice a dynamic zero with the line full and pumps running at normal temperature gives better results.
Oil and gas terminals use Elite series meters for crude oil transfer and bunker fuel measurement. Food and beverage plants use them for high viscosity molasses, chocolate and concentrated juice. Chemical firms install them on acid skids and polymer feed lines. Water and wastewater plants use them for flocculant dosing where mass flow is more reliable than volumetric flow.
A seawater flow meter for desalination plant discharge lines needs 316L wetted parts and a transmitter housing that survives salt air. We have supplied such units to sites in Oman and Southeast Asia. We have seen a paint manufacturer in Southeast Asia replace an old positive displacement meter with a DN25 Coriolis meter because the old meter needed frequent gear replacement from solvent attack.
Silver Automation Instruments offers high accuracy Coriolis mass flow meters for the same process ranges. Our units support DN15 to DN300 line sizes and mass flow accuracy of 0.1 to 0.2 percent depending on the model. For most industrial applications outside custody transfer this is enough. The price position is lower than Emerson Micro Motion Elite hardware but the material and output options are similar.
As a flow meter manufacturer and supplier we stock or build Coriolis meters with 316L stainless steel and Hastelloy C-22 tubes. Output cards include 4-20 mA HART, Modbus RTU and pulse. ATEX and IECEx approvals are available for Zone 1 gas and dust areas. If you need a direct supplier for a skid builder in Latin America or a distributor in Africa we can provide test reports and data sheets before shipment.
Here is the thing. A flow meter quote loses value if the process conditions are missing. We need the fluid name, mass flow range in kg/h, viscosity in cP, process temperature in °C and pressure in bar. Also note the pipe diameter DN and hazardous area requirement if any.

If you are comparing Emerson Micro Motion Elite hardware with a Silver Instruments Coriolis meter tell us the model number and we will prepare a line by line technical comparison at no charge.
For many process lines yes in terms of flange size, 4-20 mA HART output and accuracy class. Custody transfer approvals may still require the original Elite meter. Send us the existing model number and fluid data for a technical check.
Elite sensors often specify 0.05 percent of rate for liquids. Silver Instruments Coriolis meters specify 0.1 to 0.2 percent depending on line size and calibration. Many batching and dosing applications accept 0.1 percent.
We supply DN15 to DN300. Small DN15 and DN25 meters are common for chemical dosing. DN80 and DN100 meters fit truck loading and reactor feed. DN150 to DN300 units serve offloading and brine transfer.
