Flow Switch With Non-Contacting Sensor

Control Flow from outside a pipe. Recommended for "difficult liquids" including wastewater, cooling water, slurries, sludge, chemicals, viscous liquids and abrasives. The Greyline DFS 5.1 is ideal for pump protection or to activate flow/no-flow alarms.

Easy to Calibrate

The DFS 5.1 control relay can be set to turn ON and OFF at any flow rate between 0.25 and 10 ft/sec (0.075 to 3 m/sec). Insert two links for separate ON/OFF set points or just one link for a Hi or Lo flow alarm. Set the relay actuation time delay from 0 to 80 seconds.

A bright LED indicator shows the relay state and a LED bargraph shows the flow rate. Electronics are housed in a watertight polycarbonate wall-mount enclosure.

The clamp-on ultrasonic sensor mounts on the outside of metal or platic pipes without cutting the pipe or shutting down flow. It works on any pipe diameter 1/2" or larger and installs in minutes. There are no moving parts and no maintenance is required. .
