A particle velocity probe is a probe capable of measuring the acoustic particle velocity. Currently there are two commercially available particle velocity probes. The first one is produced by Microflown Technologies. The particle velocity transducer is called the Microflown. The second particle velocity transducer is manufactured by Weles ...
A sound velocity probe is a device that is used for measuring the speed of sound, specifically in the water column, for oceanographic and hydrographic research purposes.
A sound intensity probe is a probe capable of measuring sound intensity. The sound intensity is the product of sound pressure and particle velocity. Common probes measure the sound intensity using two microphones. Another type measures the sound intensity using a microphone and a particle velocity probe.
A pitot tube (/ ˈ p iː t oʊ / PEE-toh; also pitot probe) measures fluid flow velocity. It was invented by French engineer Henri Pitot and published in 1732, [ 1 ] and modified to its modern form in 1858 by Henry Darcy . [ 2 ]
Besides considering microphones that measure sound pressure, it is also possible to use a particle velocity probe to measure the acoustic particle velocity directly. The particle velocity is another quantity related to acoustic waves however, unlike sound pressure, particle velocity is a vector. By measuring particle velocity one obtains a ...
Other sensors include hydrophones for measuring sound in water, particle velocity probes for localizing acoustic leakage, sound intensity probes for quantifying acoustic emission and ranking, or accelerometers for measuring vibrations causing sound.
Acoustic Doppler velocimetry (ADV) is designed to record instantaneous velocity components at a single-point with a relatively high frequency. Measurements are performed by measuring the velocity of particles in a remote sampling volume based upon the Doppler shift effect.
Medical ultrasonic transducers (probes) come in a variety of different shapes and sizes for use in making cross-sectional images of various parts of the body. The transducer may be used in contact with the skin, as in fetal ultrasound imaging, or inserted into a body opening such as the rectum or vagina .
