The Yokogawa ROTAMASS Supreme series represents the absolute pinnacle of industrial Coriolis mass flow and density measurement technology. Engineered for high-end process loops and critical custody transfer applications, this premium flowmeter resolves the industry's most punishing telemetry challenges—including multi-phase flow fluctuations, entrained gas, and severe thermal shocks.
Featuring an advanced dual bent-tube design with optimized structural decoupling, the ROTAMASS Supreme delivers flawless mass balance computations and real-time inline concentration auditing. Backed by Yokogawa's proprietary Total Insight predictive diagnostics framework, it monitors internal sensor integrity 24/7, permanently eliminating unexpected drift and reducing total cost of ownership (TCO) across complex process networks.

To secure maximum low-flow metrological precision, Coriolis flowmeters require a proper field zero-point verification during initial startup or routine turnaround schedules. Follow this professional workflow:
Flush the meter with the target process medium until the transmitter housing and the dual internal measuring tubes reach full operational temperature and pressure. The fluid inside must be 100% free of ambient vapor pockets or gas cavities.
Close your downstream shut-off valve first, then close the upstream isolation valve. The Coriolis meter must remain completely full of fluid under pressure, but with absolutely zero moving velocity or hydraulic pulsation.
Access the transmitter interface or your control room software console. Navigate to the Maintenance Menu, select "Zero-Point Adjustment", and execute the automated routine. The transmitter will measure baseline phase shifts for roughly 30 to 60 seconds and flash a 'Calibration Successful' confirmation code.

Get a Commercial Quote in 2 HoursA: The ROTAMASS Supreme is specifically optimized for severe industrial conditions. It features unmatched digital signal processing for advanced aeration handling (gas entrainment), predictive Total Insight diagnostics, and structural decoupling that insulates the meter from external plant vibrations and extreme process piping stresses.
A: For liquid process media, the meter provides a high mass flow accuracy of up to ±0.1% of rate. For gaseous fluid streams, it maintains a precise accuracy profile of up to ±0.35% of rate, making it a reliable choice for commercial fiscal billing and custody transfer.
A: Yes. The ROTAMASS Supreme carries complete global explosion-proof and intrinsically safe approvals, including ATEX, IECEx, FM (USA/Canada), and INMETRO. Additionally, it features SIL 2 functional safety certifications (SIL 3 capable) right out of the box.
A: To withstand aggressive, highly acidic, or abrasive chemical process flows, wetted elements can be ordered in 316L Stainless Steel (1.4404), Alloy C-22 (2.4602) for high-grade corrosion protection, or standard 304 Stainless Steel depending on your application needs.
