Detection of presence or absence of flow of a liquid in a pipe under pressure.
The liquid must be free of magnetic particles.

The CDP operates a switch outside the liquid: The flow drives the paddle. A magnet on top of paddle actuates a Reed contact, located outside the fluid. The reverse movement of the paddle is generated by a leaf-spring.

These controllers offer a simple, reliable and inexpensive solution for flow monitoring in pipelines.

CDP controllers are mounted in-line, pipes up to ND 50 with a Tee, BSPF threads. For larger diameters, CDP must be mounted on-line, on an adaptor BSP ½'' female thread.

Accessories:
- The Reed contact has a low switching power: The use of a relay ES 2001 (doc. 250-02) will protect the Reed and allows a remote
loop signal with greater breaking capacity on a change-over relay output (500 VA/ 250 V A / 5A - 1A/ 125 V DC/ 40 W).
