A mass flow controller is designed and calibrated to control a specific type of liquid or gas at a particular range of flow rates. The MFC can be given a setpoint from 0 to 100% of its full scale range but is typically operated in the 10 to 90% of full scale where the best accuracy is achieved.
The inlet pressure gauge will indicate this pressure. The gas then passes through the normally open pressure control valve orifice and the downstream pressure rises until the valve actuating diaphragm is deflected sufficiently to close the valve, preventing any more gas from entering the low pressure side until the pressure drops again.
Instrumentation controls the operation of process columns. Instrumentation is used to monitor and control the process plant in the oil, gas and petrochemical industries. . Instrumentation ensures that the plant operates within defined parameters to produce materials of consistent quality and within the required specifica
A gas meter is a specialized flow meter, used to measure the volume of fuel gases such as natural gas and liquefied petroleum gas. Gas meters are used at residential, commercial, and industrial buildings that consume fuel gas supplied by a gas utility. Gases are more difficult to measure than liquids, because measured volumes are highly ...
Regulators can be designed to control anything from gases or fluids, to light or electricity. Speed can be regulated by electronic, mechanical, or electro-mechanical means. Such instances include; Electronic regulators as used in modern railway sets where the voltage is raised or lowered to control the speed of the engine
Gas turbine engines are primarily controlled by the amount of fuel supplied to the combustion chambers.With this in mind we can say that, the very simplest fuel control for a turbine engine is a fuel valve operated by the pilot.
An industrial control system (ICS) is an electronic control system and associated instrumentation used for industrial process control.Control systems can range in size from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems (DCSs) with many thousands of field connections.
Today "gas flow computers" as such have become uncommon, since gas flow computing is a subfunction of a data acquisition and control program implemented with programmable logic controller (PLCs) and remote terminal unit (RTUs); with the rise of smart transmitters in the early 1980s, these functions have also been incorporated within the field ...
