Doppler Flow Switch
Control Flow from outside
a pipe. Recommended for "difficult liquids"
including wastewater, slurries, sludge, chemicals, viscous
liquids and abrasives. The Greyline DFS-II is ideal for pump
protection or to activate flow/no-flow alarms.
The non-intrusive DFS-II strap-on Sensor
mounts on any pipe over 1/2" diameter without cutting the
pipe or shutting down flow. It installs in minutes and
requires no maintenance. Includes one 5 amp DPDT control
relay with 0-60 second adjustable time delay. Bright LED
indicators show relay status and signal strength. Electronics
are housed in a watertight enclosure and Sensor cable is
shielded and can be extended up to 500 ft. (152 m).
