CDP-P series liquid flow switch is designed for managing flow changes, which is commonly used for chain reaction or “no flow” protection. A reactive force is induced in the paddle in proportion to the rate flow in the pipe, and the reaction in turn generates a proportional resistance in the control spring.
Thus, a variable force balance is maintained between the flow and the control spring until the flow exceeds a set flow rate. When the flow reaches the set point, the Reaction Plate activates the micro-switch to make or break the contacts.
The threshold ranges listed are for water at 20˚C with horizontal pipe. Mounting could be on a vertical pipe with ascending flow. Then, the threshold value will be greater than the one of table. The pipe slope of a flowing down piping must be less than 40%.
