Advanced Coriolis Technology for Accurate Mass Flow Measurement
The Yokogawa ROTAMASS Total Insight (TI) is a high-performance Coriolis mass flow and density meter designed for accurate measurement of liquids, gases and challenging process media.
Unlike traditional volumetric flowmeters, ROTAMASS directly measures mass flow, making measurement less affected by changes in fluid density, viscosity or flow conditions. In addition to mass flow, the meter simultaneously measures density and temperature, allowing users to obtain additional process information such as volume flow, concentration and other calculated values.
ROTAMASS TI is designed around Yokogawaβs Total Insight concept, providing not only accurate measurement but also improved commissioning, diagnostics, maintenance and lifecycle management.
Direct Measurement of Mass Flow, Density and Temperature
The ROTAMASS TI uses the Coriolis measurement principle to provide direct mass flow measurement without requiring additional compensation for changing process conditions.
Depending on configuration, the meter can provide:
Mass flow measurement
Density measurement
Temperature measurement
Volume flow calculation
Reference density calculation
Concentration measurement of solutions, suspensions and emulsions
Viscosity calculation for Newtonian liquids
Energy/heating value calculation for gas applications
This makes ROTAMASS suitable for applications where accurate material balance, dosing control, product quality monitoring or custody transfer measurement is required.

Box-in-Box Sensor Design for Better Stability
A key advantage of ROTAMASS TI is Yokogawaβs Box-in-Box sensor structure.
This design helps isolate the measuring tubes from:
External vibration
Pipeline stress
Mechanical forces caused by installation conditions
The result is improved zero stability and reliable measurement accuracy, especially in demanding industrial environments.
No Straight Pipe Requirement for Easier Installation
