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

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

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

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

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

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

Sight flow indicators provide a quick, reliable and economical way to verify the flow of fluids through industrial process lines

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

Paddlewheel flow meters have a paddle wheel that is perpendicular to the flow path. The rotor axis is positioned to limit contact between the paddles and the flowing media

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

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

Metering pumps are precision pumps, which dispense an exact amount of material. They are used in a variety of chemical dosing and metering 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

Air velocity flow sensors measure air velocity or volume flow using insertion probes or capture hoods
