Flow Switches

Flow Switches

A flow switch is a tool used to start and stop an electric current in a circuit, just like all other switches. A flow switch is crucial for monitoring and managing the flow rate of process media, such as steam, liquids, and gases, in an industrial system. Flow switches activate actions in multiple machines throughout a system to offer on/off flow control of process media, helping to maintain safe and controlled rates of flow.
