Flow Switch, Inline Body, Full Swing Paddle

The Delta Controls Model 624 Flow Switch is highly reliable full swing, inline body switch. The paddle body fits into and becomes an unobstructed part of the pipeline. Model 624 is equipped with a full swing paddle and has an open bore matching the pipeline’s. The 624 has a flat blade-type paddle that rotates 90 degrees in response to increased flow rate. The switch actuates at a pre-calibrated set point. The paddle moves until it is flush against the pipeline wall. The body bore is unobstructed, and the flow is unrestricted. The 624 has a negligible pressure drop at high velocities for 2 inch to 8 inch (50 to 200 millimeter) pipelines with flow velocities possible in excess of 50 feet per second (15 meters per second).

The paddle is magnetically connected to the output switch. A heavy-duty solid sealing tube separates the process fluid from the switch mechanism, eliminating failures due to seal, diaphragm, bellows corrosion and leaks.
