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
Variable air volume — (VAV) is a technique for controlling the capacity of a heating, ventilating, and/or air conditioning (HVAC) system. The simplest VAV system incorporates one supply duct that, when in cooling mode, distributes approximately convert|55|F supply air … Wikipedia
Variable valve timing — Variable valve timing, or VVT, is a generic term for an automobile piston engine technology. VVT allows the lift or duration or timing (some or all) of the intake or exhaust valves (or both) to be changed while the engine is in operation. Two… … Wikipedia

Variable valve actuation — Variable Valve Actuation, or VVA, is a generalised term used to describe any mechanism or method that can alter the shape or timing of a valve lift event within an internal combustion engine. There are many ways in which this can be achieved,… … Wikipedia
Variable Cam Timing — Variable Camshaft Timing (VCT) is an automobile variable valve timing technology developed by Ford. It utilizes electronically controlled hydraulic valves that direct engine oil into the camshaft phaser cavity. These oil control solenoids are… … Wikipedia
Flow Java — is a conservative extension to the Java programming language.It integrates single assignment variables and logic variables, to Java.Its development was influenced by Mozart/Oz.Conceptually, the extension is similar to adding immutable futures but … Wikipedia
Flow control valve — Globe control valve with the pneumatic actuator and smart positioner A flow control valve regulates the flow or pressure of a fluid. Control valves normally respond to signals generated by independent devices such as flow meters or temperature… … Wikipedia
Variable Cycle Engine — In a Variable Cycle Engine (VCE) the engine cycle is deliberately modified from that which would occur under normal circumstances.The next generation of Supersonic transport (SST) may require some form of VCE. SST engines require a high Specific… … Wikipedia
Variable force solenoid — A variable force solenoid (VFS) is an electro hydraulic device that controls pressure proportionally or inversely proportionally to a signal (voltage or current) obtained from the on board controller of a powertrain. A low flow VFS is used as a… … Wikipedia
