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

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

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 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.

Flow transmitters provide electrical outputs that are proportional to flow inputs.

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.

Paddlewheel flow meters have a paddle wheel that is perpendicular to the flow path.
