The flow of liquid drives the paddle which actuates a Reed contact via a magnet mounted on the top of the paddle. A second magnet in opposition, pushes back the paddle when flow is decreasing. This design allows the CDP 57 controller to be mounted in any position.
Mounting precautions: Mounting could be on a vertical pipe with ascending flow; Then, threshold value will be greater than the one of table. The pipe slope of a flowing down piping must be less than 40 %.
Note: An amplifier relay ES 2001 will protect the Reed contact and allows a switching power of up to 500 VA / 250 V AC / 5 A – 1 A / 125 V DC / 40 W).
