Gas flow meters are used for measuring the flow or quantity of a moving gas in an enclosed pipe or passage

Volumetric gas flow switches are devices with a switch output used for measuring the flow or quantity of a moving gas in terms of a unit of volume per unit time, such as cubic feet per minute

Gas pressure regulators reduce the pressure of a gas, as it passes through a cylinder or process line, to another piece of equipment. Regulators are not flow control devices. They are used to control delivery pressure only

Gas flow switches and liquid flow switches, velocity, are used to measure the flow or quantity of a moving fluid in terms of velocity, such as feet per minute

Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas

Gas filtration elements are designed to remove particulates from a gaseous process stream. They are used in natural gas processing systems and gas extraction applications

Mass liquid flow switches and mass gas flow switches are devices used for measuring the flow or quantity of a moving liquid or gas in terms of a unit of mass per unit time, such as pounds per minute. These devices may be sensors with electrical output or may be stand-alone instruments with local displays and controls

Gas sensors interact with a gas to initiate the measurement of its concentration. The sensor then provides output to an instrument to display the measurements

Gas and air instruments detect, monitor or analyze gases present in an environment

Gas generators provide an onsite supply of gas, vapor or humidity (water vapor) eliminating the need for delivery in gas cylinders

Gas compressors and systems are used to circulate gas through a process, enhance conditions for chemical reactions, provide inert gas for safety or control systems, recover and recompress process gas, and maintain correct pressure levels by either adding and removing gas or vapors from a process system

Gas chromatographs separate organic chemical mixtures according to physical properties

Flow computers, totalizers, and rate indicators integrate the functions of flow and temperature measurement, computation, data acquisition, input / output (I/O) standardization, and closed loop control. They require external sensor inputs and may be used as local rate indicators

Process dryers are used to remove liquids or moisture from bulk solids, powders, parts, continuous sheets or other liquids by evaporation or sublimation.

Residual gas analyzers (Rags) identify the gases present in vacuum environments
