A velocity measurement has two parts ... speed and direction.
Things like a car's speedometer do NOT qualify, since they measure
only speed but not direction. I've been able to think of two devices
that monitor and indicate both of those components. I hope other
contributors will drop in and add to the list.

Average velocity is def.ined as the ratio of total displacement to total time taken.
The atmosphere has numerous measurable properties, including pressure, temperature, humidity, velocity. Each of these is measured by a different instrument. Pressure is measured by a barometer, temperature is measured by a thermometer, etc.That would be a barometer. I assume you are referring to atmospheric pressure.
An anemometer measures wind velocity.

When are air velocity measurement used
A stream gauge is the instrument which is commonly used for the measurement of velocity stream.
A pitot tube. It's a pressure measurement instrument used to measure fluid flow velocity.
wind velocity
Velocity A Vector is the measurement of velocity and direction.
In physics, velocity is the measurement of the rate and direction of change in the position of an object.

No. A vector is any measurement where a direction is relevant. Velocity is one such measure, but there are others, unrelated to velocity (for instance, force).
A measurement that has magnitude and direction. The magnitude is equal to the absolute value of the vector measurement. For example, Velocity is a vector measurement. A velocity of -20 miles per 1 second would suggest moving away from the origin point in a two-dimensional measurement at a rate of 20 miles per 1 second. The absolute value of this would be 20 miles per 1 second, which would also be the speed. Therefore, speed is the magnitude of Velocity. Subsequently, any measurement that has a magnitude, but no direction, is not a Vector measurement, but rather a scalar measurement. Some examples of vector measurements would be Displacement, Velocity, and Acceleration.
There are many instruments for measuring speed but I am not aware of any for measuring velocity.
Speed or velocity.
An anemometer.
