Coriolis mass flow meters measure the mass flow of liquids, such as water, acids, caustic, chemicals, and gases/vapors. Because mass flow is measured, the measurement is not affected by fluid density changes.

 

  The mass flow meter does not measure the volume per unit time (e.g., cubic meters per second) passing through the device; it measures the mass per unit time (e.g., kilograms per second) flowing through the device. Volumetric flow rate is the mass flow rate divided by the fluid density. If the density is constant, then the relationship is simple. If the fluid has varying density, then the relationship is not simple. The density of the fluid may change with temperature, pressure, or composition, for example

 

  Rheonik Messgeräte GmbH has more than twenty years of experience in the field of Coriolis Mass Flow meter design and development. Beginning in 1984, Karl Küppers began the design of a mass flow meter based upon the Coriolis effect that later became the patented Omega tube Coriolis Mass Flow meter manufactured by Rheonik today. 

 

  All Rheonik coriolis mass flow meters are based on a patented Omega tube design with increased signal-to-noise ratio, for excellent performance and reliability. The combination of a patented torsion rod swinger with the Omega shape and support bars results in high accuracy measurement independent of pressure, even at very low flow velocities.

 RHM coriolis flow sensors offer direct mass flow rate for liquids, sludge, and gases, all with high accuracies. These sensors are extremely resistant to gas bubbles entrained in the process stream, and are unaffected by viscosity, density, extreme temperatures, and pressure changes.There’s a Rheonik RHM flowmeter for nearly any flow application range.
