DFS2 Doppler Flow Switch

Quick Overview

The DFS2 Doppler Flow Switch continuously measures the velocity of fluid in pipelines using the non-intrusive Doppler principle. The DFS2 is quick and easy to install with no holes in the pipe, no sensor fouling, no maintenance and no downtime for sensor installation. The DFS2 includes a relay with adjustable high and low setpoint control and adjustable delay-on and delay-off timers. The DFS2 has two selectable flow ranges, 0 - 2m/s and 0 - 6 m/s, with the flow rate indicated on the 10 LED bar graph flow indicator.
