Flow controllers monitor and maintain flow-rate variables, typically in process applications.

Positive displacement flow meters measure the volume or flow rate of a moving fluid or gas by dividing the media into fixed, metered volumes. These devices consist of a chamber that obstructs the media flow and a rotating or reciprocating mechanism that allows the passage of fixed-volume amounts.

Ion lasers function by stimulating the emission of radiation between two levels of an ionized gas. They provide moderate to high continuous-wave output of typically 1 mW to 10 W.

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

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

Solids flow meters measure the flow rate of bulk solids, powders, grain, etc.

A mass flow meter is a device that consist of a mass flow sensor or transducer and signal processing electronics.  Fluid (liquid or gas) flow is measured in mass rate units (lbs/min).

Liquid flow meters are used for measuring the flow or quantity of a moving fluid.

Ultrasonic flow meters use sound frequencies to determine flow rates. They do not work well with liquids with suspended solids or air gaps.

Turbine flow meters measure the rate of flow in a pipe or process line via a rotor that spins as the media passes through its blades.

Rotameters are typically tapered glass tubes positioned vertically in the fluid flow. A float within the tube rides upward in relation to the amount of flow.

Industrial gases are pure elements, molecular compounds or mixtures that are gaseous or vaporous at room temperature and pressure.

Lasers are devices that produce intense beams of monochromatic, coherent radiation. The word "laser" is an acronym for Light Amplification by Stimulated Emission of Radiation.

Meter provers and flow proving components provide a known traceable volume to simulate actual operating conditions to test and verify the performance of flow meters and transfer meters.

Electronic and semiconductor gases are specialized for microelectronic manufacturing or semiconductor processing applications such as thin film deposition (CVD, PVD), etching, RTP, packaging or soldering.
