Difference between AC and DC

A flow switch is an essential electro-mechanical device designed to monitor the flow rate of a liquid or gas within a pipe or duct system. Its primary function is to detect whether the media flow is present or absent, or if it has fallen below or exceeded a pre-set level. When the flow reaches this specific set point, an internal mechanism (such as a paddle or piston) is actuated. This action triggers a built-in electrical switch, which can then send a signal to an alarm, a control panel, or aut
