Vortex Flow Meter List
Vortex Flow Meter
Vortex flow meters are designed so that an obstruction is placed in the path of the flow. By doing so it forces the gases or liquids to find a way around the object, once the flow moves around the object two vortexes are created on opposite sides of the object which alters the pressure of the flow.
Vortex flow meters are highly resistant to vibration, unlike other types of mass flow meters, and for this reason may be used in harsh processes and environmental conditions. The materials used vary depending on which substances will be used with the device. Stainless steel is the most common material; depending on which substances the flow meter will come into contact with, different grades of stainless steel are used with varying corrosion-resistant and strength properties. Vortex flow meters are used for in many industrial applications for flow measurements to help companies determine profit gain or loss as well as for efficiency purposes.
A vortex flow meter usually includes a bluff body, a vortex sensor and transmitter electronics which may be located in the assembly or mounted remotely. The majority of vortex flow meters use piezoelectric or capacitance sensors to detect the pressure changes around the bluff body. These flow meters may range in size from ½ inch to a foot in diameter. The bluff body is available in square, rectangular, T, and trapezoidal shapes; the best shape varies with each installation and application. It must be wide enough to accommodate the entire flow of the liquid or gas with protruding edges to correct any flow separation that occurs.
There are very many other kinds of flow meters aside from the vortex design including orifice, venture, positive displacement, turbine, electromagnetic, Doppler Effect, Coriolis, thermal mass, and more. Thermal mass flow meters take measurements by calculating how much heat loss occurs in the flowing liquid.Coriolis flow meters operate on the basis of the Coriolis Effect in which, an excitation force is applied to the flow meter tube, causing the fluid or gas to rotate because the acceleration acts in opposite directions on both sides of the applied force. Doppler Effect flow meters are ultrasonic and use sound to operate.
