Model 624 • Flow Switch, Directly Inserted, Full Swing Paddle Features Non-restricting full open bore Highly reliable magnetic coupling Compact size Description The Delta Controls Model 624 Flow Switch is highly reliable and the paddle body fits into and becomes part of the pipeline. Model 624 is equipped with a full swing paddle and has an open bore matching that of the pipeline. The 624 has a flat blade-type paddle that rotates 90 degrees in response to increasing flow rate. At a pre-calibrated set point, the switch actuates. The paddle moves until it is flush against the inside of the pipeline wall. The body bore is then unobstructed and flow is unrestricted. The 624 has a negligible pressure drop at high velocities for 2 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. Failures due to seal, diaphragm, bellows corrosion and leaks are eliminated.
