Vortex Flow Meters

The construction of the meter is fairly simple: an obstruction is placed directly in the flow path, forcing liquids or gases to move around it. When the flow moves around this obstruction, or bluff body, two symmetrical vortices are created on the opposite side, changing the pressure of the flow. Read More...

Vortex Flow Meters Vortex flow meters measure the flow rate of liquids, gasses, and steam by measuring the differential pressure of vortexes created in a substance's flow.

Vortex Flow Meters List

A sensor is placed between two vortices created by an obstacle in the center of a flow stream, put there to measure changes in pressure, transmitting this data to an electronic signal conditioner outside the meter. Because the principle used in the vortex flow meter is naturally occurring and requires no moving parts, vortex flow meters can measure a wide range of viscosities and do not depend upon uniform density.

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.

Coriolis Flow Meters

Coriolis Flow Meters

A Coriolis flow meter measures mass by the inertia of a liquid or gas flowing through a vibrating tube that is equipped with a set of sensors at the inlets and outlets of the meter. The increased movement of the flow produces measurable oscillation that is proportional to the mass...

Magnetic Flow Meters

Magnetic Flow Meters

A magnetic flow meter is a volumetric flow meter that uses electrodes connected to the liquid flow to measure the velocity of fluids in a tube or pipe. The unique design of magnetic flow meters allows them to take their readings without the need for any moving parts...

Mass Flow Meters

Mass Flow Meters

A mass flow meter is a way of measuring the volume or mass of a gas or liquid passing through a system at a specific point in the flow system. They are used to measure linear, nonlinear, mass, and volumetric flow rates...

Rotameters

A rotameter is a device that measures the flow of fluid volume per unit time in a closed tube. There are diverse rotameters applications, including chemical injection/dosing and tank blanketing. A rotameter can be said...

Ultrasonic Flow Meters

Ultrasonic Flow Meters

An ultrasonic flow meter measures the flow of a liquid or gas by sending ultrasonic waves across a pipe, containing the flow in the direction of the flow and in the opposite direction of the flow. The ultrasonic waves and the velocity of...
