Rotamass Total Insight (TI), Yokogawa’s Coriolis mass flowmeter, provides very high accuracy for measuring liquids and gases while adopting the Total Insight concept and totally supporting the product lifecycle.
From the direct mass flow, density, temperature measurements, with Rotamass TI you can calculate:
With additional measurement input Rotamass TI can calculate fluid viscosity for Newtonian liquids or energy-heating value for gas measurement.
Experience Meets Innovation
The Coriolis Mass Flow and Density Meters with superior performance under demanding conditions.
The successful Rotamass series has been progressively developed and is also newly equipped with the latest technology. This meter delivers unsurpassed performance for demanding and critical applications with superior aeration handling and advanced diagnostic functionality.
