Reducing Process Variablity by Using Faster Responding Flowmeters in Flow Control
نویسندگان
چکیده
The dynamic response characteristics of flowmeters are often not considered when selecting a flowmeter for use in flow control applications. It is generally assumed that slow controller sample rates make flowmeter response a moot issue. This assumption is shown to be incorrect. It is demonstrated that the use of faster responding flowmeters will always result in reduced process variability, regardless of the controller sample rate.

Thermal Simulation of Solidification Process in Continuous Casting
In this study, a mathematical model is introduced to simulate the coupled heat transfer equation and Stefan condition occurring in moving boundary problems such as the solidification process in the continuous casting machines. In the continuous casting process, there exists a two-phase Stefan problem with moving boundary. The control-volume finite difference approach together with the boundary ...
متن کاملThe Long Term Calibration Stability of Critical Flow Nozzles and Laminar Flowmeters
The National Institute of Standards and Technology (NIST) has performed calibrations of gas flowmeters using piston and bell provers for three decades. Most of the meters calibrated have been either critical flow nozzles or laminar flowmeters since these meter types are generally chosen as the working standards or transfer standards by other flow calibration laboratories. Often the same meters ...
متن کاملUpgrade of the Gas Flow Control System of the Resistive Current Leads of the LHC Inner Triplet Magnets: Simulation and Experimental Validation
The 600 A and 120 A circuits of the inner triplet magnets of the Large Hadron Collider are powered by resistive gas cooled current leads. The current solution for controlling the gas flow of these leads has shown severe operability limitations. In order to allow a more precise and more reliable control of the cooling gas flow, new flowmeters will be installed during the first long shutdown of t...
