Vortex flow measurement

SITRANS FX is your all-in-one vortex solution for volumetric and mass
flow measurement of steam, gases and liquids - and so much more. These
reliable all-rounders integrate flow, pressure and temperature
monitoring into one user-friendly, 2-wire device. You benefit from
enhanced energy and process efficiency, greater accuracy and significant
cost savings. From saturated and superheated steam to raw chemicals,
from compressed air to crude oil, measure it all with SITRANS FX. A
compelling combination of features puts Siemens vortex flowmeters in a
league of their own.

Specifications
Vortex meters measure flow by
detecting the frequency at which alternating vortices are shed from a
bluff body, which is hit by the medium. The vortices create a
differential force across a sensor wing, flexing it at a frequency
proportional to the flow rate measured by the meter. The movement of the
oscillating wing is transmitted to the SITRANS FX electronics by a dual
piezoelectric crystal sensor mounted in the wing.
