Advances in flow metering technology mean more options for a broad spectrum of processes and flows. One such specialized technology is the vortex flow meter, an innovative flow measurement device capable of handling liquids, gases, steam, and corrosive applications. A large variety of industries can benefit from vortex technology. It is well-suited for any application where clogging or leaks occur, steam measurement is needed, or where Safety Instrumented Systems (SIS) are used. These flow meters have exceptional capabilities and benefits worth exploring, reducing inefficiencies and increasing safety in industries across the board.| Quantity: | |

The Technological Edge of Vortex Flow Meters
Vortex flow meters are composed of three main parts: a body, a sensor, and a transmitter. As the process flow moves through the body of the meter, an obstruction called a shedder bar forces the flow around it, creating vortices. An oscillating sensor measures these areas of alternating differential pressure. The frequency of this movement allows for the use of the von Kármán effect to calculate the volumetric flow rate.
This distinctive arrangement means that there are no moving parts within the meter to maintain or repair. Emerson’s unique design utilizes vortex technology with a non-wetted sensor, making on-line maintenance possible. In the rare occasion that the vortex sensor needs to be replaced, sensor replacement can be performed without breaking the process seal.
Vortex flow meters are easy to install without impulse lines and can withstand high process pressures and temperatures. They are used in a broad spectrum of processes because they have a wide turndown range. Emerson’s special non-clogging and non-leaking vortex flow meters mean improved sensor accuracy and safety, especially in hazardous chemical applications. They are also a two-wire device with low power consumption making them excellent choices for use in remote areas. 002
