Flow Switches

Flow switches are designed to control the movement of gas, steam or liquid in a process, by triggering a predetermined action such as on or off. Flow switch sensors with an electrical contact output at a specific flow rate have different types of switches, such as paddle, thermal, piezo and shuttle/piston.
