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

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

Open channel flow sensors measure fluid flow through open channels

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

Weather instruments are designed to measure one or multiple components of weather including wind speed and direction, rain or snow fall, solar radiation, temperature, pressure and humidity.

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

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

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.

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.

Dry material (powders) level sensing devices are used to measure levels of solid, dry materials in either continuous or point values represented with various output options.

Laboratory fume hoods are partially enclosed workspaces that are exhausted to the outside.

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.

Non-destructive testing (NDT) conductivity meters and resistivity meters are devices for measuring electrical conductivity and/or resistivity of solid media to determine the characteristics of its constituent materials.

Regenerative blowers are low pressure, high volume blowers that generate centrifugal airflow.  They are used in compression, vacuum, and industrial blower applications

Imaging workstations are vision systems used for metrology or image analysis in laboratory and cleanroom settings.
