Vortex Flow Meters

The Vortex meter series VTX is equipped with a trapezoidal bluff body which induces a precise detachment of vortices with high repeatability. Liquids, gases and steam can be measured equally well. Due to the special design of the bluff body the frequency of the vortices is proportional to the flow velocity and independent from pressure, temperature, density and viscosity. The vortices, detaching reciprocally from the bluff body, engender local changes in velocity and pressure, which are detected by a sensor and converted to a signal (4-20mA or NAMUR pulses) by a transmitter, equipped with an auto-adaptive and microprocessor-driven signal processing.
