Six Coriolis flowmeter suppliers active in 2026 cover nominal sizes from DN 1 to DN 200, with combined flow-rate reach from 0-40 kg/h micro-flow units [S4] to 2,200,000 kg/h bulk-line meters [S5], and process-temperature ceilings as high as 350°C / 662°F [S3].
Selection is no longer about whether a Coriolis exists for a given service line; it is about matching tube geometry, wetted material, and accuracy class to the duty. The supplier list below spans global majors, mid-tier specialists, and low-cost Asian OEMs, with sizes from DN 1 to DN 250 / 10" [S1][S3][S5].
Supplier-by-supplier size and flow coverage in 2026
ABB's CoriolisMaster FCB400 ships in DN 15 to DN 150 (1/2" to 6") with flow ranges of 0-8,000 kg/h up to 0-860,000 kg/h and ATEX zone 0/1/2 plus cFMus Div 1/2 hazardous-area approvals on a single build [S1]. Siemens' SITRANS FC family, distributed by ICS Schneider, spans FCS100 (DN 1 to DN 8, 21-950 kg/h) through FCS700 (DN 100 to DN 200, 250,000-900,000 kg/h), with wetted material options of stainless steel AISI 316L or Alloy 22 across the smaller FCS100/700 lines [S3].
Endress+Hauser's Promass catalogue, redistributed via the Intrepid Group, lists 39 current-generation models plus 10 legacy units. The flagship Promass F 100/300/500 hits ±0.10% standard, ±0.05% optional accuracy on flows up to 2,200,000 kg/h and process temperatures from -50°C to +350°C, while single-tube Promass A variants (A 100/200/300/500) handle 0-450 kg/h micro-flow at ±0.1% [S5]. Specialized Promass variants exist for CNG, LPG, LNG, and dosing duties within the same family [S5].
Low-cost and mid-tier Coriolis OEM options from China and Asia
Silver Automation Instruments sells micro-low-flow Coriolis units starting at 0-40 kg/h for custody transfer and pilot lines, advertising ±0.1% to ±0.2% mass-flow accuracy with simultaneous density, temperature, and pressure outputs [S4]. AFT Instruments positions its Coriolis mass flowmeter line for chemical, petroleum, and food batching/blending/custody transfer, emphasising mounting-effect minimisation and stable measurement under fluctuating process conditions [S6].
OVAL's VRmass (model CV006 to CV050) covers 10 mm to 50 mm (1/2" to 2") with 0.4-20 kg/min up to 32-1600 kg/min flow spans, SUS316L wetted parts, ±0.4% factory calibration plus zero-stability error, and process connections per JIS 10/20/30K, ANSI/JPI 150/300 RF, or ferrule joint [S2]. Maximum operating pressure on the VRmass line is 7.9 MPa at ambient temperature, with the integral transmitter rated -25°C to +125°C and the remote configuration rated -40°C to +125°C [S2].
Accuracy, temperature, and pressure comparison across the 2026 supplier set
The best-in-class accuracy tier is ±0.05% (optional) on Endress+Hauser Promass F 100/300/500, with mass flow, density, temperature, and (in many lines) viscosity measured simultaneously [S5]. Siemens' SITRANS FC620/FC640 pushes process-temperature capability to 350°C / 662°F and pressure to 700 bar / 10,153 psi relative, targeted at extreme industrial service rather than hygienic duty [S3]. ABB's FCB400 holds the broadest hazardous-area envelope of the surveyed set: ATEX zone 0/1/2 and cFMus Div 1/2 with zone 0/1/2 on the same meter build [S1].
For low-flow duties, the Siemens FCS100 (21-950 kg/h, DN 1-DN 8, Alloy 22 tubes) and Silver Automation's micro unit (0-40 kg/h minimum) lead the size envelope, while OVAL's VRmass sits between them at 0.4-20 kg/min (24-1,200 kg/h) with 316L wetted parts and a 7.9 MPa ceiling [S2][S3][S4]. For hygienic and food/beverage/pharma service, Siemens specifies AISI 316L tubes and dedicated hygienic process connections on the FCS500 / FC520 / FC540, with flow from 1,600 kg/h up to 170,000 kg/h across DN 10 to DN 80 [S3].
Selection gates: which supplier fits which duty
For custody-transfer and high-accuracy batching, the Endress+Hauser Promass F 300 / F 500 at ±0.05% to ±0.10% over 0-2,200,000 kg/h and -50°C to +350°C is the default spec, particularly when viscosity is required alongside mass flow and density [S5]. For extreme-temperature or high-pressure process lines (hot oil, chemical reactors, high-pressure injection), Siemens SITRANS FC620/640 at 350°C / 700 bar is the correct pick [S3]. For hazardous-area chemical and petroleum skids needing zone 0 mounting, ABB FCB400's combined ATEX 0/1/2 + cFMus Div 1/2 rating is the differentiator [S1].
For pilot plants, R&D, and high-value fluid additives below 1,000 kg/h, the Siemens FCS100 / FC120 / FC140 (DN 1-DN 8, Alloy 22) and Silver Automation's micro Coriolis (0-40 kg/h) are the engineered choices [S3][S4]. For cost-sensitive general-liquid, slurry, and food-duty lines in the 0.4-1,600 kg/min band, OVAL VRmass with 316L wetted parts and JIS/ANSI flange or ferrule connections is the budget option [S2]. For batching and blending with mounting-effect compensation in chemical, petroleum, and food plants, AFT Instruments' Coriolis mass flowmeter line targets that duty profile directly [S6].
Process-fluid and installation constraints buyers should price in
Coriolis meters measure mass flow, density, and temperature directly, and (on E+H Promass lines) viscosity as a fourth output, with no straight-pipe run required upstream or downstream [S5]. Two parallel flow tubes (a "rainbow" geometry) provide self-drainage and clean-in-place compatibility, which is why the OVAL VRmass and Siemens FCS500 / FC520 are explicitly built for hygienic service [S2][S3]. Single-tube designs (Endress+Hauser Promass A 100/200/300/500) shrink the wetted envelope for the lowest flow rates at 0-450 kg/h, useful when the process line is small and cleanability of the sensor is the priority [S5].
For slurry and viscous service, the rainbow-tube design's self-drainage and ability to handle particulates is the engineering reason suppliers keep that geometry in the food and chemical lines [S2]. Wetted-material selection (AISI 316L versus Alloy 22) is driven by chemical compatibility and process temperature: Alloy 22 extends corrosion resistance on the SITRANS FCS100 / FCS700 lines, while 316L is the standard for the FCS500 hygienic family [S3]. See coriolis flowmeter selection: tube, accuracy, and duty map for the decision flow that ties tube geometry to fluid class. Related flow-measurement comparison material, including the electromagnetic flowmeter selection: liner, electrode, and conductivity gates guide, helps separate when a mag meter is the better fit (conductive clean liquids) versus a Coriolis (mass-flow custody transfer, hydrocarbons, slurries). For buyers cross-referencing flow measurement against the broader flow meter category, the coriolis flowmeter reference page consolidates operating-principle detail across this same supplier set.
