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.
