Flow Cytometers

(23 companies)
Flow cytometers use laser beams to characterize single cells as they pass by at high speed.
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.
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.

Liquid Flow Meters

(598 companies)
Liquid flow meters are used to measure the volumetric flow rate or amount of a moving liquid.
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.
Flow orifices and flow restrictors contain precision-machined holes and filters or screens to restrict flow and reduce pressure. They are available as stand-alone devices and in kits, assemblies, restrictors, and restrictor valves.
Open channel flow meters measure fluid flow through open channels.

Solids Flow Meters

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

Vortex Flow Meters

(128 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.

Mass Flow Switches

(37 companies)
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.

Ultrasonic Flow Meters

(232 companies)
Ultrasonic flow meters use sound waves to determine flow rates. They can be either Doppler Effect meters or Time-of-Flight meters.

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.

Turbine Flow Meters

(276 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.
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

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