Categorized by characteristics such as flow material, measurement type and design, flow switches are used in diverse industries including HVAC, industrial, pharmaceutical, food and chemical processing, water treatment and commercial.

There are many different types of flow switches, the most common of which include gas, liquid, volumetric and velocity flow switches. The first two types are characterized by the flowing material, whereas the last two are characterized by measurement type; thus, these types can intermingle such as a volumetric gas flow switch or a liquid velocity flow switch.

Flow switches at their most basic consist of a valve body, sensing devices and a switching unit that is connected to a pipeline. Gas flow switches include materials such as air and steam and are most often used in HVAC applications.

Liquid flow switches include a much longer list of materials, which includes water, lubricants, coolants, chemicals and slurries, and are vital to many industrial applications. Volumetric flow switches, on the other hand, can measure the flow of liquids or gases. The most important characteristic of a volumetric flow switch is that it measures the flow of the material based on volume per unit time, an example of which is cubic feet per minute.

Conversely, velocity flow switches measure the flow rate of a moving material in terms of velocity, of which an example would be feet per minute.
