Flow measurement — is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive displacement flow meters acumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow… … Wikipedia
Tracer — may refer to: *Histochemical tracer, a substance used for tracing purposes in histochemistry, the study of the composition of cells and tissues *Isotopic tracer, a substance with an isotope that has been enriched to a greater level than that… … Wikipedia
Flow tracer — A flow tracer is any fluid property used to track flow. The concentration of a chemical compound in the fluid can be used as a chemical tracer, and characteristics such as temperature are physical tracers. Tracers may be artificially introduced,… … Wikipedia
Tracer-gas leak testing method — As part of the recommended leak testing methods for nondestructive testing several tracer gas leak testing ones exist among which the methods of choice are: * Helium mass spectrometer or helium leak detection, providing the highest sensitivity *… … Wikipedia
Flow visualization — In fluid dynamics it is critically important to see the patterns produced by flowing fluids, in order to understand them. We can appreciate this on several levels: Most fluids (air, water, etc.) are transparent, thus their flow patterns are… … Wikipedia

tracer — 1. An element or compound containing atoms that can be distinguished from their normal counterparts by physical means ( e.g., radioactivity assay or mass spectrography) and can thus be used to follow (trace) the … Medical dictionary
Semiconductor curve tracer — The Type 575 Transistor Curve Tracer displays the dynamic characteristic curves of both NPN and PNP transistors on the screen of a 5 inch cathode ray tube. Several different transistor characteristic curves may be displayed, including the… … Wikipedia
Perfluorocarbon tracer — Perfluorocarbon tracers (PFTs) are a range of perfluorocarbons used in tracer applications. They are used by releasing the PFT at a certain point, and determining the concentration of that PFT at another set of points, allowing the flow from the… … Wikipedia
