Flow switches are either mechanical or electronic devices that provide a signal to an operator or control system that the flow rate is exceeding or has fallen below a setpoint value. When the flow rate is above (high flow) or below (low flow) the setpoint, electronic flow switches trigger an output signal, typically a relay or transistor, to change state. The change in state can be applied as a warning, an alarm signal, to adjust a process control device, suspend or shut-down the process, etc
