The Yokogawa ROTAMASS Total Insight (TI) platform represents the cutting edge of multi-variable Coriolis metrology under demanding field conditions. By integrating direct high-frequency mass flow, real-time density matrix, and synchronous temperature polling, the ROTAMASS series ensures unsurpassed calibration stability even during severe process aeration or multi-phase fluid transitions. From micro-dosing chemical injection loops to bulk marine loading arms, this portfolio optimizes the entire facility lifecycle by reducing maintenance dropouts and lowering Total Cost of Ownership (TCO).
ROTAMASS Nano: Tailored for micro-dosing loops, laboratory pilot plants, and ultra-low fluid chemical treatments. Supports high pressures up to 460 BAR with an accuracy threshold of ±0.1%.
ROTAMASS Prime: The general-purpose industrial workhorse for everyday process control, blending loops, solvent tracking, and mass balance systems.
ROTAMASS Hygienic: 3-A and EHEDG certified with mirror-polished 316L wetted surfaces for aseptic food, beverage, WFI, and biotechnology fermentation lines.
ROTAMASS Supreme: Engineered to withstand severe thermal shocks from deep cryogenic liquified gas fields up to high-heat furnace feeds (-196°C to +350°C).
ROTAMASS Intense: The ultimate high-pressure safety container rated up to 700 BAR (10,000 PSI) with integrated rupture disks for offshore downhole chemical injection.
ROTAMASS Giga: High-bore fiscal loading master spanning sizes from DN100 to DN250. Optimized for custody transfer billing in oil terminals and LNG lines.

In batching loops or tank de-bottoming runs, transient gas pockets (void fractions) create massive oscillation damping inside Coriolis sensor loops. While standard flow meters experience complete drive-gain failure during these phases, Yokogawa’s advanced electronics deploy real-time structural stabilization. Execute this engineering optimization to handle high aeration:
Step 1. Enable Dual-Frequency Tracking: Access the transmitter configuration menu via HART or Modbus. Toggle the multi-phase processing function to 'Active'. This instructs the pick-up coils to decouple gas bubble phase offsets from core liquid mass resonance.
Step 2. Set the Low-Flow Cut-off Profiles: Under multi-phase flow conditions, back-pressure fluctuations can distort data. Calibrate the low-flow cut-off threshold at exactly 0.5% of nominal capacity to keep spurious gas spikes from corrupting totalizer counts.
Step 3. Activate the Gas Void Fraction Alarm: Bind a programmable relay output to the Gas Void Fraction (GVF) variable. This provides continuous data tracking for automated valve compensation networks during two-phase fluid states.
We supply only 100% factory-original Yokogawa ROTAMASS assemblies with full manufacturer tracking tags intact. Every item is verified by hydrostatic validation test blocks prior to dispatch and ships in uncompromised Yokogawa industrial packing. Comprehensive documentation packs—including original system calibration certs, dynamic hydro-test sheets, and standard EN 10204 3.1 Material Test Certificates (MTC)—are bundled with every shipment to satisfy internal plant compliance protocols.

Request Full Sizing & RFQ Support (Responses within 2 Hours)A: Total Insight (TI) is an integrated firmware concept that runs advanced internal health diagnostics across the instrument's entire lifespan. It incorporates continuous Tube Health Verification, internal drive gain trend tracking, and custom data-logging via microSD. This allows maintenance teams to satisfy regulatory auditing schedules without shutting down process pipelines.
A: By combining precision density mapping with a high-resolution platinum temperature probe, the ROTAMASS transmitter computes the absolute mass balance ratio between two miscible or unmiscible fluids. It directly outputs continuous inline metrics for Net Oil Computing, Water-Cut monitoring, and custom sugar concentration (°Brix) setups without external data processors.
A: Yes. While standard configurations feature high-grade 316L Stainless Steel, severe chemical pipelines can upgrade wetted elements to premium Alloy C-22 (2.4602). This provides elite resistance against severe pitting, crevice erosion, and hydrogen sulfide stress cracking common in upstream refining loops.
