Yokogawa ROTAMASS Total Insight Coriolis Mass Flowmeter
Overview: Six Dedicated Product Lines, One Unified Concept
The Yokogawa ROTAMASS TI (Total Insight) is a Coriolis mass flow and density meter that directly measures mass flow rate using the Coriolis principle, providing very high accuracy for measuring liquids and gases while adopting the Total Insight concept to support the product across its full lifecycle. Rather than offering a single general-purpose sensor, Yokogawa organizes ROTAMASS TI into six dedicated product lines – Nano, Prime, Hygienic, Supreme, Intense, and Giga – each optimized for a specific combination of flow range, process condition, and application, paired with a choice of Essential or Ultimate transmitter for the right balance of functionality and cost.
As a trusted supplier of Yokogawa flow instrumentation, Seven Star LLC sources and supplies the ROTAMASS TI Coriolis flowmeter to petrochemical, chemical, and food and beverage facilities across Oman and the wider GCC. Because selecting the correct product line and transmitter combination materially affects measurement performance, Seven Star LLC helps engineering teams match the right ROTAMASS TI configuration to their specific process fluid and conditions.
Measurement Principle
A Coriolis flowmeter measures mass flow directly using the Coriolis force (F = 2mωv), generated as fluid moves through the oscillating sensor tubes: the phase shift this creates is directly proportional to mass flow rate, while the energy required to maintain tube oscillation reveals fluid density, together providing both mass and volumetric flow without any external compensation for temperature or pressure. This direct measurement principle is why ROTAMASS TI can simultaneously report mass flow, density, temperature, and calculated values such as volume flow, concentration, viscosity, or energy-heating value from a single sensor.
Yokogawa’s patented box-in-box sensor design optimally decouples the core measuring element from external influences, providing vibration immunity that is particularly valuable on ships, compressor skids, and other high-vibration installations. Dynamic Pressure Compensation keeps mass flow and gas volume measurement accurate and reliable even as line pressure fluctuates, and the Tube Health Check function detects stiffness changes in the measuring tubes caused by corrosion, abrasion, or clogging – changes that would otherwise silently affect mass flow accuracy.
Engineering Design of the ROTAMASS TI Family
Each product line targets a specific niche: Nano is the world’s smallest dual bent tube Coriolis meter for lowest-flow dosing and metering (DN15-DN40, -50 to +260°C, up to 285 bar); Prime is the versatile, cost-effective general-purpose line with superior turndown (DN15-DN125, -70 to +200°C); Hygienic is EHEDG- and 3-A-certified for food, beverage, and pharmaceutical service; Supreme handles aggressive liquids and gases with superior aeration handling; Intense is rated to 700 bar for high-pressure chemical injection, hydraulics, and hydrocarbons; and Giga delivers best-in-class accuracy at high flow rates (DN100-DN200) for bitumen, LNG, and loading applications.
Both the Essential and Ultimate transmitters share a common platform: the Essential provides a multi-lingual setup wizard, NAMUR NE107 event management, microSD data logging, Tube Health Check, and HART or Modbus communication, while the Ultimate adds in-line concentration measurement, API-compliant Net Oil Computing, Dynamic Pressure Compensation, batching, viscosity functions, and PROFIBUS PA, FOUNDATION Fieldbus, or PROFINET over Ethernet-APL communication with Features on Demand for post-installation function upgrades. SIL2 (SIL3 in redundant configuration) certification and hazardous-area approvals including ATEX, IECEx, FM, and NEPSI support safety-critical and classified-area installations.

Industrial Applications
ROTAMASS TI is deployed across petrochemical plants, chemical processing, food and beverage manufacturing, and marine bunkering applications, with typical uses including batching, blending, chemical injection, custody transfer, net oil computing, and concentration measurement. Its Nano, Intense, and Giga lines extend Coriolis measurement into low-flow dosing, high-pressure chemical injection, and large-diameter high-flow applications respectively, covering a far broader range than a single general-purpose Coriolis meter could address.
Seven Star LLC supports petrochemical plants, chemical processors, and food and beverage manufacturers across Oman, Muscat, Sohar, and the broader GCC region with sourcing of Yokogawa ROTAMASS TI Coriolis flowmeters, helping projects select the correct product line for their process.

Product Line Selection by Connection Size and Flow
Each ROTAMASS TI line covers a defined band of connection sizes and flow. Nano (meter sizes Nano 06 to Nano 20) uses DN15 to DN40 connections and reaches 1.5 t/h, with a flat accuracy specification starting at 2.5 kg/h. Prime (Prime 25 to Prime 1H) spans DN15 to DN125 and 255 t/h. Supreme (Supreme 34 to 39) covers DN15 to DN125 and 170 t/h. Intense (Intense 34 to 38) takes connections up to 2 in and 50 t/h. Hygienic (Hygienic 25 to 80) covers DN25 to DN80 and 76 t/h, and Giga (Giga 1F and 2H) covers DN100 to DN200 and 600 t/h.
Temperature and pressure narrow the choice further. Supreme is the only line specified from -196 °C for cryogenic fluids up to 350 °C, with factory-fitted or customer-fitted insulation and heat tracing for viscous or molten fluids. Intense is built for process pressures up to 700 barg (10000 psig) with Alloy C-22 wetted parts. Prime and Giga are rated to 100 bar. Hygienic is limited to 140 °C and is offered with DIN 11851, SMS 1145 and clamp connections. In every line the allowed pressure depends on the chosen process connection and the process temperature, so both must be stated in the enquiry.
Essential or Ultimate Transmitter
Position 1 of the ROTAMASS TI model code selects the transmitter: E for Essential, U for Ultimate, or N for a spare sensor without transmitter. Essential is the general-purpose version with HART or Modbus communication, Tube Health Check, Total Health Check and data backup on a microSD card, with liquid mass flow accuracy down to 0.15 or 0.2% depending on the line and density accuracy down to 4 g/l. It suits duties where mass flow and density are the only values needed and no application function has to run in the meter.
Ultimate brings liquid mass flow accuracy down to 0.1% and density accuracy down to 0.5 g/l, and adds PROFIBUS PA and FOUNDATION Fieldbus to HART and Modbus. It also carries the application functions: standard and advanced concentration measurement, Net Oil Computing following the API standard, viscosity function, batching function and heat quantity measurement, with further functions activated later through Features on Demand. Integral and remote designs are offered, except Nano, which is remote type only. For safety loops Yokogawa states an exida certificate to IEC 61508:2010 with SIL 2 at HFT 0 and SIL 3 at HFT 1.
