Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas. Search by Specification | Learn More
Gas flow meters are used for measuring the flow or quantity of a moving gas in an enclosed pipe or passage. Search by Specification | Learn More
Ultrasonic flow meters use sound waves to determine flow rates. They can be either Doppler Effect meters or Time-of-Flight meters. Search by Specification | Learn More
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. Search by Specification | Learn More
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. Search by Specification | Learn More
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. Search by Specification | Learn More
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. Search by Specification | Learn More
Flow switches are devices that monitor flow and send a trip signal to other devices, like a pump, for protection. These switches can be used for the measurement of gases, liquids, and steam. Search by Specification | Learn More
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. Search by Specification | Learn More
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). Search by Specification | Learn More
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. Search by Specification | Learn More
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. Search by Specification | Learn More
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. Search by Specification | Learn More
