The
DFS 5.1 Clamp-On ultrasonic Flow Meter is 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.
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 an LED bar graph 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 plastic
pipes without cutting the pipe or shutting down flow. It works on any
pipe diameter 1/2″ (12.5 mm) or larger and installs in minutes. There
are no moving parts and no maintenance is required. The shielded sensor
cable length is 20 ft. (6 m) and can be extended up to 500 ft. (152 m)
with an optional Junction Box.
SPECIFICATIONS
- The flow switch shall operate with a clamp-on ultrasonic sensor mounted externally on any contiguous pipe material that conducts sound including carbon steel, stainless steel, ductile iron, copper, FRP, PVC, ABS, or cement lined pipe from 1/2″ to 180″ (12.5 mm to 4.5 m) diameter.
- Shall operate on liquids with entrained particles or gases of 100 microns or larger and minimum concentrations of 75 ppm.
- The control ON and OFF set-points shall be independently adjustable for flow rates between 0.25 ft/sec (0.076 m/sec) and 10 ft/sec (3 m/sec).
