Yokogawa ROTAMASS Total Insight Coriolis Mass Flowmeter

Overview: Six Dedicated Product Lines, One Unified Concept

The Yokogawa ROTAMASS Total Insight (TI) 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 an authorized 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 460 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-DN250) 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.

Key Features

The Yokogawa ROTAMASS Total Insight Coriolis Flowmeter delivers direct, multi-variable process measurement. Key characteristics include:

• Direct mass flow, density, and temperature measurement via the Coriolis principle.
• Six dedicated product lines (Nano, Prime, Hygienic, Supreme, Intense, Giga) for application-specific optimization.
• Patented box-in-box sensor design for vibration immunity and decoupling from external influences.
• Tube Health Check and Total Health Check for in-line meter verification without process disruption.
• SIL2 (SIL3 redundant) certification; ATEX, IECEx, FM, NEPSI hazardous-area approvals.
• Ethernet-APL support with PROFINET Conformance Class B and PA Profile 4.0 function blocks.
• Essential or Ultimate transmitter options, with Features on Demand for post-installation upgrades.

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.
