Volumetric liquid flow switches measure the flow or quantity of a moving fluid in terms of a unit of volume per time, such as liters per minute. These flow sensing devices have a switch output.

Velocity Flow Switches

(78 companies)
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.
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.

Vortex Flow Meters

(121 companies)
Vortex flow meters are flow sensors that detect the frequency of vortices shed by a bluff body placed in a flow stream. The frequency of the vortices is proportional to the flow velocity.

Liquid Flow Meters

(601 companies)
Liquid flow meters are used to measure the volumetric flow rate or amount of a moving liquid.

Paddlewheel Flow Meters

(74 companies)
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.
Mass flow meters and controllers measure flow rate in units of mass or volume per units of time (e.g., pounds per minute). They are designed for use with gases, liquids, steams, or slurries.

Turbine Flow Meters

(275 companies)
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.

Solids Flow Meters

(31 companies)
Solids flow meters measure the flow rate of bulk solids, powders, grain, etc.

Sight Flow Indicators

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

Ultrasonic Flow Meters

(223 companies)
Ultrasonic flow meters use sound waves to determine flow rates. They can be either Doppler Effect meters or Time-of-Flight meters.
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.
Electromagnetic flow meters operate on Faraday's law of electromagnetic induction, which states that a voltage is induced when a conductor moves through a magnetic field.

Control Knobs

(112 companies)
Control knobs are used for the control or adjustment of electronic or electrical devices.

Control Panels

(757 companies)
Control panels are used to receive inputs, trigger outputs, and monitor systems and instrumentation. They are used in a variety of industrial, manufacturing and process control applications.
