This movement triggers a switch that can be used for various applications such as controlling the flow of liquid or shutting down a system in case of a blockage. Neither A) pilot tube, B) Bourdon tube, nor C) bulb are typically used in flow switches. A flow switch typically contains a paddle or vane that is displaced when there is a flow of liquid or air. This displacement activates a switch or other mechanism to signal flow or no flow.
