Doppler Flow Switch - DFS-II - Greyline Instruments - #4

The DFS-II flow sensor installs without cutting the pipe. It takes just a few minutes to mount on the outside of any pipe. The switch/electronics enclosure can be mounted 20 ft (6 m) away from the sensor (optional up to 500 ft /152 m) to simplify wiring to pumps, alarms, valves or other equipment.

Switch adjustments and electrical connections are fast and easy. The DFS-II relay time delay is adjustable from 0 to 60 seconds to prevent nuisance alarms and relay "chatter" in turbulent flow. Includes switch selectable "normal" and "failsafe" operating modes.

d No contact with the measured liquid

d No obstruction to flow - No pressure drop

d Sensor mounts easily on the outside of the pipe

d Can be installed while pipe line is in use

d Insensitive to pressure, specific gravity and conductivity

d Does not require pipe metering sections

d Does not require consideration of material compatibility with the liquid Repeatable, Reliable Flow Control

Use the DFS-II for pump protection, valve control and flow/no-flow alarms. It is ideal for "difficult" liquids like wastewater, slurries, abrasives and chemicals, or any liquid which contains gas bubbles or solids. The standard Sensor mounts on any pipe 1" (25 mm) diameter or larger.
