The Dwyer SERIES V7 Flotect® Flow Switch is an inexpensive range switch for use with compatible liquids to start or stop electronic operated equipment when flow or no-flow conditions occur. Design is standard weatherproof, meeting NEMA 4X.
- Proof of boiler flow
- Shuts down burner when airflow through heating coil fails
- Protects pumps, motors, and other equipment against low or no flow
- Stops liquid-cooled engines, machines, and processing when coolant flow is interrupted
