A Raman anemometer for component-selective velocity measurements of particles in a flow [PDF]

, 1981
An anemometer for the measurement of the velocity of particles of different components in a flow, separate and apart from that of the flow itself, is described. As a component-selective mechanism Raman scattering is used.

Measurement and control systems for an imaging electromagnetic flow meter [PDF]

, 2014
Electromagnetic flow metres based on the principles of Faraday's laws of induction have been used successfully in many industries. The conventional electromagnetic flow metre can measure the mean liquid velocity in axisymmetric single phase flows ...

Development of Measurement Method for Temperature and Velocity Field with Optical Fiber Sensor

Sensors, 2023
We have developed a new method for measuring temperature and velocity at a high spatial resolution (minimum 2.56 mm pitch along an optical fiber). The developed method uses the same principle as a hot wire anemometer, where the velocity perpendicular to ...

Velocity selector with a microwave magnetic dipole transition

, 2014
We proposed a method based on microwave magnetic dipole transitions to prepare samples of atoms with well defined position and velocity. Each microwave pulse corresponds to a position measurement for the atoms and two pulses separated by a given delay ...

Drift velocity of electrons in silicon at high electric fields from 4.2° to 300°K [PDF]

, 1969
The drift velocity of electrons in silicon at high electric fields is measured in the direction over the range of lattice temperatures from 4.2° to 300°K. It is established that in this range a limiting drift velocity exists.
