A Thorpe tube flowmeter, a type of variable-area flowmeter, or a rotameter, is an instrument used to directly measure the flow rate of a gas in medical instruments. It consists of a connection to a gas source, a needle valve opened and closed by turning an attached dial for control of flow rate, a float resting in a clear tapered tube, and an ...
A rotameter is an example of a variable area meter, where a weighted "float" rises in a tapered tube as the flow rate increases; the float stops rising when area between float and tube is large enough that the weight of the float is balanced by the drag of fluid flow. A kind of rotameter used for medical gases is the Thorpe tube flowmeter ...
A rotameter is a device that measures the volumetric flow rate of fluid in a closed tube. [ 1 ] It belongs to a class of meters called variable-area flowmeters , which measure flow rate by allowing the cross-sectional area the fluid travels through to vary, causing a measurable effect.
C-50 (50% argon/50% CO 2) is used for short arc welding of pipes, C-40 (60% argon/40% CO 2) is used for some flux-cored arc welding cases. Better weld penetration than C-25. C-25 (75% argon/25% CO 2) is commonly used by hobbyists and in small-scale production. Limited to short circuit and globular transfer welding.
Diargon or the argon dimer is a molecule containing two argon atoms. Normally, this is only very weakly bound together by van der Waals forces (a van der Waals molecule ). However, in an excited state , or ionised state , the two atoms can be more tightly bound together, with significant spectral features.
The quality of a speaker's soundstage depends not only on the sound that travels in a direct path from the speaker to your ears, but also on the sound that reflects off your walls before you hear it.
Argon ST was created with the merger of SenSyTech, Inc. and Argon Engineering Associates on September 29, 2004. In August 2006, Argon ST acquired Innovative Research, Ideas & Services Corporation (IRIS), the authors of the sensor fusion software Transducer Markup Language (TML) .
Argonne has five areas of focus, as stated by the laboratory in 2022, including scientific discovery in physical and life sciences; energy and climate research; global security advances to protect society; operating research facilities that support thousands of scientists and engineers from around the world; and developing the scientific and technological workforce.
