Dwyer Instruments V10 1/2 Inch Mini Brass Flotect Flow Sw

The Dwyer Instruments V10 1/2 Inch Mini Brass Flotect Flow Switch is a compact and dependable device that detects the presence or absence of flow in liquids or gases. Its 1/2 inch NPT male connection and compact brass body make installation in pipelines simple. An electrical signal is produced inside by a tiny paddle that travels with the flow to activate a magnetic reed switch. The V10 is perfect for many HVAC applications because of its straightforward yet efficient mechanism, which guards against dry running of pumps, regulates their sequential operation, and sounds an alert when there is little or no flow.
