Endress + Hauser’s Coriolis Mass Flowmeters

Simultaneous measurement of mass flow, density, and temperature opens up entirely new perspectives for process control, quality assurance, and plant safety. Additional important characteristic values can also be calculated from the primary variables measured:

  • Volume flow
  • Solids content in a fluid
  • Concentrations in multiple-phase fluids
  • Special density values such as reference density, °Brix, °Baumé, °API, °Balling, °Plato, etc

Coriolis flow measuring principle

Each Coriolis flowmeter has one or more measuring tubes which an exciter causes to oscillate artificially. As soon as the fluid starts to flow in the measuring tube, additional twisting
is imposed on this oscillation due to the fluid‘s inertia. Two sensors detect this change of the tube oscillation in time and space as the “phase difference.” This difference is a direct measure of the mass flow.

In addition, the fluid density can also be determined from the oscillation frequency of the measuring
tubes. The temperature of the measuring tube is also registered to compensate for thermal influences. The process temperature derived from this is available as an additional output signal.


  • Universal measuring principle for liquids and gases
  • Multivariable measurement – simultaneous measuring of mass flow, density, temperature, and viscosity
  • High measuring accuracy: typically ±0.1% o.r., optionally: ±0.05% o.r. (PremiumCal)
  • Measuring principle independent of the physical fluid properties and the flow profile
  • No inlet/outlet runs necessary

    Just thought I would comment and say neat theme, did you design it for yourself? Looks superb!

      Thanks You, I had designed it for my potential client for review.
