Fuel is the single largest operating cost for any vessel. The Yokogawa ROTAMASS TI Supreme is the core component of Insatech Marine’s performance systems, engineered to deliver precision in the most volatile engine room environments.
Ships are high-vibration environments. Standard Coriolis meters often struggle with "noise" and mechanical stress, leading to measurement drift. The ROTAMASS TI Supreme addresses this with its Patented Box-in-Box Design.
Vibration Immunity: The dual-case design isolates the measuring tubes from ship-born vibrations and piping stress.
Space-Saving Installation: Unlike volumetric or ultrasonic meters, the ROTAMASS requires zero straight pipe runs, allowing for easy retrofitting in cramped engine rooms.
DNV Certified: Fully Type Approved by DNV (formerly DNV-GL), ensuring the meter meets the rigorous safety and quality standards required for global maritime operations.
Traditional fuel measurement relies on volume, which fluctuates with temperature and density. By utilizing the Coriolis Principle, the ROTAMASS TI Supreme provides direct mass measurement:
No Compensation Needed: Eliminates the need for external temperature sensors or density manual entries, removing the risk of "human error" in fuel reporting.
High Turndown Ratio: Maintains precision from high-flow bunkering down to low-flow idling, outperforming traditional mechanical meters across the entire engine load range.
Total Health Check: Features built-in self-diagnostics that monitor the meter’s internal integrity, ensuring your data is "audit-ready" for MRV and IMO DCS compliance.

Traditional flow systems often require a "chain" of components - temperature sensors, pressure transmitters, and flow computers - to calculate mass flow. Every link in that chain is a potential point of failure or miscalculation.
Eliminate Calculation Drift: The Yokogawa ROTAMASS provides direct mass and density signals. By removing the need for external compensation, you eliminate the mathematical "offsets" that occur as fuel temperature or viscosity fluctuates.
Tamper-Proof Data: Direct signals from the meter to your monitoring system (like a Fuel Management System) reduce the risk of manual data manipulation, ensuring your MRV and IMO DCS reporting is audit-ready and accurate.
Advanced Diagnostics: Integrated self-monitoring provides real-time health checks, alerting the crew to sensor issues before they impact performance data.
While many Coriolis meters are sensitive to the physical stresses of a vessel - such as thermal expansion of piping, hull torque, and engine vibration - the ROTAMASS TI Supreme is purpose-built for these conditions.
The Box-in-Box Advantage: Our patented dual-case design acts as a mechanical "decoupler." The outer casing absorbs the external stresses of the engine room, allowing the inner measuring tubes to oscillate freely and accurately.
Reduced Installation Costs: Because the meter is immune to most piping stresses, it does not require the expensive, space-consuming "support frames" or specialized alignment often needed by inferior meters.
Mechanical (Positive Displacement) meters are prone to wear and clogging, especially when handling Heavy Fuel Oil (HFO) with high sulfur or catalytic fines. The ROTAMASS TI Supreme changes the maintenance paradigm:
No Moving Parts: With no rotors, gears, or bearings to wear out, the internal risk of breakdown is virtually zero.
Filter-Free Installation: Unlike volumetric meters that require fine-mesh strainers (which frequently clog and cause pressure drops), the ROTAMASS sensor is insensitive to particles in the fuel stream.
Crew Efficiency: By eliminating filter cleanings and periodic recalibrations, your crew can focus on mission-critical performance tasks rather than routine instrument maintenance.
In maritime instrumentation, the "cheapest" option often becomes the most expensive over a 5-year lifecycle. When evaluating the ROTAMASS TI Supreme, we encourage owners to look at the Total Cost of Ownership (TCO):

Conclusion: Cutting costs on the initial purchase often leads to higher fuel slippage, increased maintenance man-hours, and unreliable data. Selecting the ROTAMASS TI Supreme is an investment in long-term vessel efficiency and regulatory compliance.
Selecting a flow meter is a decision that impacts a vessel's operational expenses (OPEX) for a decade or more. At Insatech Marine, we guide owners to choose instruments that don't just meet today’s requirements but are scalable for future environmental regulations and digital transformation.
For most onboard engine room installations, Insatech Marine recommends a remote-mounted transmitter setup (where the converter is separated from the flow tube).
Vibration Decoupling: By separating the sensitive electronics (transmitter) from the fuel line (sensor), we significantly increase the lifespan of the instrument. This protects the converter from the constant high-frequency vibrations and thermal stress of the engine room piping.
Ease of Access: Remote mounting allows the display and controls to be placed at eye level for the crew, rather than tucked away in hard-to-reach piping runs.
Maintenance & Service: If the electronics ever require service, they can be accessed without disturbing the pressurized fuel line or the sensor itself.
The maritime industry is shifting toward data-driven reporting (CII, EEXI, and EEOI). Choosing the ROTAMASS TI Supreme ensures your vessel is ready for these changes:
Software-Ready Upgrades: Through "Features on Demand," you can unlock advanced functions like Viscosity or Batching via a software key, without the need to replace physical hardware.
Avoid "Early-Stage" Obsolescence: While a low-cost, basic meter may work for simple flow indications today, it often lacks the digital output and diagnostic depth required for future performance monitoring systems, leading to expensive retrofitting costs later.
In a "low-cost" setup, the initial savings are often eclipsed by the cost of time spent on troubleshooting, frequent zero-point adjustments, or premature failure due to vibration fatigue. A future-proven instrument ensures:
Lower Retrofitting Costs: One installation that lasts the lifetime of the vessel.
High Data Integrity: Reliable data for fuel audits and bunkering claims.
Crew Confidence: Minimal interaction required with the device once commissioned.
The Coriolis effect is a universal physical phenomenon that occurs when a mass moves within a rotating or oscillating frame of reference. In the Yokogawa ROTAMASS, this principle is harnessed to provide the most accurate flow data available to the maritime industry.
Inside the meter, a set of dual U-shaped sensor pipes is vibrated by an electromagnetic drive coil at their natural resonant frequency.
At Zero Flow: When the fuel is stationary, the upstream and downstream sections of the pipes oscillate in perfect synchronization.
During Active Flow: As fuel moves through the vibrating tubes, the Coriolis force is generated. This force acts in opposite directions on the inlet and outlet legs of the tubes, causing them to "twist."
The Result: Highly sensitive pick-up coils detect a time delay—or Phase Shift—between the two ends of the pipe. This shift is directly proportional to the mass flow rate. Because it measures mass (inertia) rather than volume, the reading remains accurate regardless of changes in temperature, pressure, or viscosity.
Simultaneously, the meter monitors the frequency at which the tubes vibrate.
The mass of the tubes plus the mass of the fluid inside them determines the vibration frequency.
A heavier fluid (higher density) causes the tubes to vibrate more slowly, while a lighter fluid allows for a higher frequency.
By measuring this frequency, the ROTAMASS provides a continuous, high-precision density measurement in real-time.
The amount of energy (current) required to keep the tubes oscillating at their resonant frequency provides further insight into the process. Sudden increases in "Drive Gain" can indicate the presence of entrained air or gas (slug flow), allowing the ROTAMASS to alert the crew to aeration issues that would compromise standard volumetric meters.
As a universal solution for liquid and gas flow, the Yokogawa ROTAMASS TI Supreme is engineered to handle the full spectrum
of marine fluids, ranging from heated Heavy Fuel Oil (HFO) to cryogenic Liquid Natural Gas (LNG). This versatility makes it the cornerstone of comprehensive fuel management, providing high-precision measurement for bunkering, fuel transfer, and consumption monitoring across all fuel grades, while simultaneously offering the precise tracking required for lube oil monitoring and optimized vessel maintenance.
For vessels operating in volatile environments, the system ensures complete safety with ATEX, IECEx, and FM certifications for hazardous area compliance. The engineering of the ROTAMASS TI Supreme also prioritizes seamless retrofitting and installation; its compact footprint requires no straight piping runs (0 x D), allowing it to be integrated into the tightest engine room configurations. Operators benefit from flexible orientation options, supporting both horizontal and upwards-vertical flow to ensure the measuring tubes remain full, while advanced aeration handling allows the meter to maintain accuracy even in real-world conditions where air-free liquids cannot be guaranteed.
In 2011 Insatech Marine initiated a collaboration with Uni-Tankers as their advisor and component supplier. Uni-Tankers is known for their innovative approach to ship operations and their constant pursuit of optimizations, like using special paint on the hull and many other optimization projects – and the only way to get insights into the effect of these initiatives is to measure fuel consumption.
Since 2014 Insatech Marine has installed more than 1,500 mass flow meters and data collection on 200+ vessels for an international shipping line to give a more detailed insight into the vessels fuel consumption to save cost and reduce their CO2-emission.
The ROTAMASS TI Supreme features a unique, patented "Box-in-Box" design that sets it apart from standard Coriolis meters. In the volatile environment of a vessel's engine room, this construction is essential for maintaining metrological integrity.
How it protects your data:
Structural Isolation: The outer casing handles all process connections and absorbs external stresses from pipe misalignment, thermal expansion, and hull torque.
Mechanical Decoupling: The inner casing houses the sensitive measuring tubes, completely isolating them from the "noise" of the piping system.
Stable Zero-Point: By diverting external forces around the sensor piping, the meter maintains an exceptionally stable zero-point, significantly reducing the frequency of recalibrations compared to single-case meters.
At Insatech Marine, our expertise extends far beyond the hardware. We ensure that your instrumentation delivers maximum value through every stage of its operational life.
