Coriolis Flowmeters

History of Yokogawa’s Coriolis Mass Flow and Density Meters

Yokogawa's Coriolis Mass Flow and Density Meters was sold worldwide in 1993 as ROTAMASS.
The first ROTAMASS was a product that improved noise resistance by adopting a self-drain structure that reduces fluid accumulation, and a Box-in-Box structure that greatly reduces piping noise and flow noise.
In the last decade, the use of Coriolis Mass Flow and Density Meters has been changing from general purpose to supporting your needs in specific applications.
While the technological complexity increased, the demand for simple operation and handling is also a rising requirement.
Yokogawa answers these needs by offering six dedicated product lines with two specialized transmitters allowing the highest flexibility -the ROTAMASS Total Insight.

Product Introduction

Rotamass TI can provide very high accuracy for measuring liquids and gases under process conditions.

From the direct mass flow, density, temperature measurements, with Rotamass TI you can calculate:

• Volume flow at operating or reference conditions
• Density at reference conditions
• Concentration measurements of mixable or unmixable fluids

With additional measurement input Rotamass TI can calculate fluid viscosity for Newtonian liquids or energy-heating value for gas measurement.
