A Rotameter with Flow Switch combines the variable area flow measurement of a rotameter with an integrated flow switch that provides an electrical output when the flow reaches a certain set point. This hybrid device allows for both visual flow monitoring and automatic flow detection or control.

• A Paddle Flow Switch is a mechanical device used to monitor the flow of liquids in pipelines. It detects flow by the movement or deflection of a paddle inserted into the fluid stream. When the flow reaches a certain set point, the paddle moves and activates an internal switch to send an electrical signal.
