A drag-type flow meter is disclosed of the type having a drag plate disposed in the fluid flow stream, the velocity of which is to be measured. The drag plate is mounted on a cantilevered arm which is pivitally mounted externally of the fluid flow passage, with a tensioned wire counteracting the drag force tending to pivot the arm. The tensioned wire is disposed in a magentic field and an electrical current is passed through the wire to cause vibration of the wire, the frequency of which varies linearly with the drag force exerted on the drag plate due to the corresponding change in wire tension. Varying frequency of the current provides a digital electrical signal which varies linearly with fluid flow velocity. Embodiments are described enclosing the wire mounting components in a vacuum housing in order to minimize the air damping of the wire vibration, and a mounting arrangement minimizing the effects of temperature variation on the output signal.

What is the principle of micromotion flow meter?
it principle denpend on what kind of flow meter. example, magnetic flow meter, it use magnetic force to measuring or coriolis flow meter which is use vibrated capilary tube as sensor. or more info you might watch on youtube.
What is the definition of viscous drag in an oil lubricant?
If a fluid in laminar flow flows around an obstacle, it exerts a viscous drag on the obstacle. Frictional forces accelerate the fluid backward (against the direction of flow) and the obstacle forward (in the direction of flow). The viscous drag force increases linearly with the speed of the fluid.
What is the force air resistance?
Air resistance is a friction force, the flow of air over a surface will cause friction and produce drag. Thanks
What is the definition of viscous drag in a liquid?
It is the '''''resistance''''' to flow in a liquid.
The SI unit of the drag force?
If you consider drag as a force, that would be Newtons.If you consider drag as a force, that would be Newtons.If you consider drag as a force, that would be Newtons.If you consider drag as a force, that would be Newtons.
What is the symbol of Flow meter?
THE SYMBOL FOR Flow Meter is : FI as Flow Indicator
What is the resistance force?
Air resistance is a friction force, the flow of air over a surface will cause friction and produce drag. Thanks
What is frictional drag?
Friction drag is the drag acting on the surface of an object from a fluid flowing over it. When a fluid flows over an object it exerts a shear force on the object because of the fluid's viscosity which pulls the object in the direction of the flow.

How does a lorry deflector use drag?
A lorry deflector uses drag reduction by redirecting air flow over the top of the vehicle, reducing the drag force experienced by the lorry. This helps improve fuel efficiency and overall aerodynamics.
What is Symbol for flow meter?
The above is the symbol of flow meter.
How would one recalibrate a flow meter?
One can recalibrate a flow meter by having a company or owning a flow meter supplier or using a flow meter lab. No matter what type of flow meter they need to be checked to see if they need to be recalibrated regularly.
