Kobold DWN Paddle Bellows Flow Monitor

Description

Kobold DWN Paddle Bellows Flow Monitor DWN works according to the diaphragm plate principle. Baffle/paddle (1) is reflected in the flow direction against the force of the spring (2) by the flowing medium. A stainless steel bellow (3) seals off the system hermetically between the medium and measuring unit/indicator. The motion is transferred positively from the baffle

(1) to the measuring section. In the measuring section, a microswitch (6) and a pilot lamp (7) are operated as soon as the set switching point is exceeded or undershot. Thus the change in flow is signaled locally by the switching point pilot lamp (illuminates for undershooting). At the same time, switching operations are triggered by the microswitch, designed as a 3-pole changeover contact.

The displacement-deflection technique is one of the most secure systems available as motion is transferred positively from the baffle plate to the measuring section. With these flow monitors, if the T piece becomes clogged up with lime, foreign objects, or dirt, the system responds with “no flow”. It is practically impossible for the system to hang up in a position that indicates flow when there is no flow.
