In this type of flow switch, as the name suggests, the fluid flow moves the vane or paddle, which in turn activates the switch. This operation can be seen in the figure below.<\/span><\/p>\n<p style=\"text-align: right;\"><span style=\"color: #000000;\">The flow switch uses the force of the fluid flow to move the paddle of the switch, which indicates the incoming flow or movement of the fluid in the pipe. When the fluid is moving, the paddle is displaced and, upon reaching the specified setpoint, sends a signal to trigger a predetermined response.<\/span><\/p>\n<p style=\"text-align: right;\"><span style=\"color: #000000;\">\u00a0This type of flow switch acts as a balancing arm between the flow rate and a control spring. When the process flow rate deviates below or above the set points, micro switches send on\/off commands. The flow switch with a float vane is designed for applications requiring long service life.<\/span><\/p>\n<p style=\"text-align: right;\"><span style=\"color: #000000;\"><img loading=\"lazy\"
