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

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

Flow switches are devices that monitor flow and send a trip signal to other devices, like a pump, for protection.

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

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.

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.
