This switch package offers a complete solution for flow or no-flow switching in pipes
or ducting up to 0.3 m (12"). The compact relay controller reliably actuates valves,
pumps, or blowers rated up to 1/2 hp. Common applications include low-flow pump
or process protection. To complete the instrumentation package, simply select the
switch configuration in accordance with the liquid or gas used in your application.
