Description

The Model DFS 5.1 is a doppler flow switch from Greyline that regulates flow with a non-contacting ultrasonic sensor that is located on the outside of pipes. It is installed quickly and easily. It does not require pipe drilling to function and needs little to no maintenance.

It is housed with a NEMA4X that provides a water tight protection to the switch. The enclosure is integrated with a 5 ampere control relay, adjustable ON and OFF set point controls, adjustable time delay, flow rate bargraph, and LEDs.

Furthermore, this device is engineered for pump protection, proper valve control, and flow/no-flow alarms. It is suitable for use with waste water, slurries, caustics, acids, and other tough fluids.
