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

Linear velocity sensors measure the linear velocity of an object using either contact or non-contact techniques

Pressure sensors include all sensors, transducers and elements that produce an electrical signal proportional to pressure or changes in pressure

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

Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance

Linear position sensors and switches, ultrasonic, are used for position and displacement sensing, using ultrasonic technology

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

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.

Open channel flow sensors measure fluid flow through open channels

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

Test equipment and instrument repair services test and repair industrial equipment and instruments. They specialize in the test and repair of acoustic and vibration equipment, electrical and electronic test equipment, laboratory equipment and instruments, inspection instruments or non-destructive testing (NDT) equipment, or specialty testing equipment and instruments.

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

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

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

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
