What is a vortex shedding flow meter?

?The VersaFlow Vortex Shedding flow meter detects the vortices that are created by a process medium going past a bluff body. The frequency of these vortices can be equated into flow velocity, which, in turn, is used to calculate volumetric flow rate.
A.

What is meant by Vortex Flow?

In fluid dynamics, a vortex (plural vortices/vortexes) is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved. A moving vortex carries with it some angular and linear momentum, energy, and mass.
  • How is a vortex formed in water?

    A drain's whirlpool, also known as a vortex, forms because of the downdraft that the drain creates in the body of water. The downward flow of the water into the drain begins to rotate, and as the rotation speeds up, a vortex forms.
  • What is meant by vortex shedding?

    In fluid dynamics, vortex shedding is an oscillating flow that takes place when a fluid such as air or water flows past a bluff (as opposed to streamlined) body at certain velocities, depending on the size and shape of the body. See Von Kármán vortex street.
  • What is Vortex in aviation?

    Wingtip vortices are circular patterns of rotating air left behind a wing as it generates lift. One wingtip vortex trails from the tip of each wing. Wingtip vortices are sometimes named trailing or lift-induced vortices because they also occur at points other than at the wing tips.
B.

How does a vortex flow meter work?

A vortex flow meter is a flow measurement device best suited for flow measurements where the introduction of moving parts presents problems. Vortex flow meters operate under the vortex shedding principle, where an oscillating vortexes occur when a fluid such as water flow past a bluff (as opposed to streamlined) body.
  • What does a Coriolis meter measure?

    A mass flow meter, also known as an inertial flow meter is a device that measures mass flow rate of a fluid traveling through a tube. The mass flow rate is the mass of the fluid traveling past a fixed point per unit time.
  • How do differential pressure flow meters work?

    Differential pressure flowmeters use Bernoulli's equation to measure the flow of fluid in a pipe. When the flow increases, more pressure drop is created. Impulse piping routes the upstream and downstream pressures of the flowmeter to the transmitter that measures the differential pressure to determine the fluid flow.

C.

What is vortex flow in a torque converter?

There are two types of fluid flow inside the torque converter. The rotary flow is the fluid flow which circulates with the converter body rotation. The fluid flow is stronger when the difference in speed between the impeller and turbine is great, eg when the vehicle is accelerating. This is called high vortex.
  • What is the stall on a torque converter?

    Torque converter stall speed is the maximum amount of engine RPM that can be achieved in an automatic transmission-equipped vehicle while the transmission is in a forward operating range without generating any driveshaft motion.
  • What is a stall speed test?

    Stall test consist of determining maximum engine speed obtained at full throttle in "D' and "R" positions. This test checks torque converter stator overrunning clutch operation, and holding ability of transaxle clutches and low-reverse brake.
  • Do all cars have a torque converter?

    The bell housing contains a torque converter for automatic transmission-equipped vehicles as opposed to a clutch on manual vehicles. The torque converter is a fluid coupling whose job it is to connect your engine to your transmission and thus to your driven wheels.
